The world of electric bicycles is rapidly gaining momentum, captivating cycling enthusiasts worldwide. These innovative vehicles offer a plethora of advantages over conventional pedal bikes, revolutionizing the way we ride. However, amidst this growing trend, many riders find themselves grappling with questions about their e-bike's battery and its optimal charging routine.
One recurring query revolves around the frequency of charging an e-bike battery. Is it best to wait until the battery is completely drained or should you avoid it altogether? The answer lies in the electric bike's built-in battery indicator, which simplifies the charging process for riders. By heeding the indicator's suggestion, you can ensure optimal battery performance and longevity.
An e-bike battery is typically discharged when it reaches its maximum range, indicating the farthest distance it can cover on a single charge. This range varies depending on the e-bike model, with some offering only pedal-assist mode while others boast a throttle mode for effortless propulsion. Additionally, the level of assistance provided by the motor significantly affects the achievable range, even without utilizing the throttle mode.
Most electric bicycles offer a range of 22 to 50 miles, though certain models can surpass these limits. These estimates are based on relaxed pedaling. However, with consistent pedaling and a high-quality e-bike, you can extend the range to approximately 80 miles, unlocking a world of possibilities.
While the battery's capacity plays a crucial role in charging frequency, other factors also impact the range:
Battery Capacity: The battery's capacity determines the frequency of charging, with higher capacity batteries requiring less frequent charges.
Terrain Type: Uphill journeys necessitate increased motor assistance, drawing more current from the battery and reducing the range. Similarly, riding against strong headwinds mimics uphill terrains, albeit on a smaller scale.
Rider's Weight: Heavier riders demand more power from the motor, resulting in increased electric current consumption from the battery.
On the other hand, descending hills or utilizing minimal assistance on flat terrain can conserve battery power. But should you deplete the battery entirely during every ride?
To maximize battery life, it is advisable to avoid frequent full discharges. Instead, aim to charge the battery when it reaches around 30% capacity and alternate between charging at 30% and 60% remaining capacity. This alternating charging pattern helps preserve the longevity of lithium-ion batteries commonly found in e-bikes. However, a complete discharge once every 30 or 40 charges can be beneficial but is not necessary. Embracing the 30%-60% rule ensures regular charging, thereby extending the battery's lifespan and your riding pleasure.
When initially charging a new e-bike battery, a 12-hour charge is recommended to ensure all cells receive an ample supply of electric current. Subsequently, avoid fully charging the battery to prevent accelerated degradation. Instead, maintain a charge level between 40% and 70% for extended storage periods. Additionally, when charging, disconnect the charger once the battery reaches 90%-95% capacity to prevent overcharging.
To further enhance battery longevity, consider the following vital charging tips:
Storage Conditions: Avoid storing the battery in excessively hot or cold environments. Optimal storage temperatures range from 59 °F (15 °C) to 77 °F (25 °C) in a dry location.
Temperature Considerations: Refrain from charging the battery in temperatures below 32 °F (0 °C). Before charging during winter, ensure the battery reaches room temperature.
Safety Precautions: Place the battery and charger on a dry surface, away from flammable materials, humidity, and heat sources. Avoid covering the battery or charger during the charging process.
Manufacturer's Charger: Always utilize the charger provided by the manufacturer to prevent potential damage to the battery.
Monthly Charges: Even during extended periods of non-use, charge the battery at least once a month to maintain its health and performance.
In summary, a simple rule of thumb is to charge your battery after each ride, adhering to the 30%-60% alternating pattern. This ensures your e-bike is always ready to hit the road whenever you desire.
However, with high-capacity batteries like the Delfast 3.0, boasting an impressive range of 200 miles (321 km), less frequent charging may be necessary for short commutes or leisurely rides. The Delfast 3.0's control display provides accurate battery charge information, making it effortless to follow the 30%-60% rule and optimize your battery usage.
Embrace these charging tips and unlock the full potential of your e-bike battery. Ride with confidence, knowing you have extended the lifespan of your battery and embarked on countless electrifying adventure
When your electric bicycle needs a new battery, you have several options. It may take some time, but electric bicycle batteries do degrade over time. If your device is old and worn out, here are various choices to consider. Following the latest industry recommendations, which suggest replacing defective or scrap batteries with "authorized technically identical batteries," may not always be practical.
Batteries are the most expensive consumables on an electric bicycle, and replacing a battery typically costs several hundred pounds.The good news is that the quality of electric bicycle batteries is generally much better than in the early days of the industry. A two-year warranty is the minimum industry standard today, and the lifespan of high-quality electric bicycle batteries should be longer than that.
The bad news is that even with frequent use, electric bicycle batteries will eventually need to be replaced.
Option 1: Replace the battery within the warranty period
Electric bicycle batteries can fail in two main ways:
1. They may become unable to charge or provide power to the motor due to issues like faulty connections or a malfunctioning Battery Management System (BMS) chip.
2. Over time and repeated use, they may gradually lose capacity to the point where the range they provide becomes impractical. All lithium-ion batteries degrade with repeated use and charging. This, in itself, is not a fault, but it does mean that even the best electric bicycle batteries have a limited lifespan.
This is an important distinction because different battery warranties cover different battery faults. For example, ChamRider guarantees their own branded batteries to have at least 60% of the original charging capacity after 1,000 charge cycles . It is the dealer's job to determine the remaining battery capacity using diagnostic software. It widely quotes a guarantee of at least 60% of full charging capacity or 500 charge cycles within two years (whichever comes first) – although I was unable to find this information on their website.
However, many other companies may simply stipulate a two-year warranty. If your battery completely fails within two years, this should provide a clear solution, but if the available capacity drops significantly within that period, it may trigger various semantic debates.
Considering all the above factors, it is best to obtain as detailed a written battery warranty as possible from the retailer at the time of purchase. It must be said that finding a clear and detailed battery warranty on the websites of electric bicycle companies is a rather challenging task.
When does a battery degrade to the point of needing replacement?
By using an inline energy meter (such as this one), you can get a very approximate understanding of the capacity of your electric bicycle battery.
First, make sure your electric bicycle battery is completely depleted by using it until the battery is empty. You should know its rated capacity in watt-hours (Wh) – for more detailed information, refer to our battery article.
Now, charge it back up to full but use the inline power meter to measure the watt-hours consumed from start to finish (i.e., after the battery is fully charged).
Not all the electricity consumed by the meter goes into the battery. For example, the transformer that reduces the voltage from 240V to the voltage required by the electric bicycle battery is inefficient and loses some electricity.
Transformers vary, but a very rough working assumption is that 80% of the power from the socket ends up in the battery.
It's best to repeat this exercise a few times to get an average reading. Clearly, this method has its limitations, but it should at least indicate any very significant shortcomings in the battery's capacity and allow you to monitor it over time. If you notice a decrease in the battery's range, it can be used to help quantify the suspected performance decline.
Option 2: Purchase a like-for-like replacement
If your battery is out of warranty, the next logical step is to purchase a like-for-like replacement. Even for electric bicycles that are a decade or more old, it is often still possible, particularly for models equipped with high-quality motor systems from brands like Bosch, Shimano, Yamaha, and Brose.
The industry advice is to only replace with a battery from the same manufacturer and with identical specifications. There are good reasons for this – the battery, controller, and motor are all designed to work together safely, and using a "non-original" replacement pack may introduce uncontrolled risks.
That being said, you can choose to upgrade to a larger capacity battery offered by the same manufacturer. Some Bosch and Shimano batteries of different capacities are explicitly interchangeable.
If your battery is out of warranty, the next logical step is to purchase a like-for-like replacement. Unfortunately, this is not always an option. Electric bicycle technology is constantly evolving, and older batteries may no longer be in production.
Option 3: Refurbishment
If your product is out of warranty and direct replacement is not possible, the next obvious step is repair or "rejuvenation" (replacing the internal cells of the battery with new ones). Rejuvenation undoubtedly carries risks, especially if you use a non-professional company, so choosing the right place for rejuvenation is crucial.
As we reported in February, the industry view expressed by CONEBI is that only original OEM-certified batteries should be used as replacements for electric bicycles. This is certainly the ideal choice for obtaining high-quality replacements, but it is often simply not possible for older electric bicycles.
Hannes De Jong runs Heskon, a leading electric bicycle recycling and repair service in Europe. He acknowledges the concerns raised by CONEBI but believes that with the maturity of the industry, refurbishment may be the way forward.
"While there are safety risks with using a small, inexperienced company for recycling or repair, I believe certification can address many of the concerns raised by CONEBI," he told us. "Most importantly, the new EU legislation that is currently being formulated should make repair/reuse the first choice."
Similarly, ChamRider notes that there are currently no clear rules specifying that repair and refurbishment services work with original manufacturers or even require them to recertify the batteries. This is precisely why De Jong wants to introduce certification standards so that professional companies like Heskon can provide reliable and sustainable services while strengthening legal standards.
Mid-drive motors of high quality have been around for decades, and there are now a large number of electric bicycles no longer in production with proprietary electronics in their original batteries. Of course, in many cases, the original suppliers and/or manufacturers of the electric bicycles cannot be traced or have ceased operations. This is where things get tricky.
Whether it is repairing completely failed batteries or, more commonly, performing a full recharge due to the decreased capacity from years of use, there are companies in the industry with a long history and good reputation. We interviewed two of them to delve into what can be done and what cannot be done.
Conclusion
Although electric bicycle battery refurbishment is a hot topic in the industry and not without risks, it has significant sustainable potential and should be organized and certified to provide cost-effective and safe options for old electric bicycles, especially when original battery replacements from the manufacturer are not available.
Recently, a reader contacted us and, after having problematic batteries refurbished at Ebike Batteries in London, they are back on the road. Another option implied by advice given by original manufacturers to customers is that the bike cannot be used as an electric bicycle anymore. This essentially means discarding a perfectly functional electric bicycle.
As a final note on battery safety, it is worth emphasizing that even with high-quality batteries, other equally important measures need to be taken.
Unsupervised charging should be avoided, especially overnight. Similarly, whenever possible, you should always use the charger provided by the original manufacturer.
The one that comes with the battery should be well-matched and not cause overcharging. Using a different charger may result in malfunctions during the charging process.
Using replacement batteries from non-original manufacturers (whether or not involving dealers) may also void the warranty for your electric bicycle or kit. Consult your electric bicycle or kit company to understand their policies regarding the use of aftermarket replacement batteries.
It may not be crucial if it allows you to continue using an old electric bicycle that would otherwise be scrapped, but as you can see from the information above, you may have other options to consider before going down that path.

Ebike battery problems can be quite frustrating. Unfortunately, they’re not uncommon at all. In fact, ebike batteries are notorious for failing after a short amount of time, which can leave you stranded or without your electric bike. Here are some tips on how to fix ebike battery problems and get back on the road.
What are the major Ebike Battery Problems?
The battery is the heart of the ebike. Without a good battery, it’s just a regular bike. So it’s important for you to learn the battery problems and how to fix them. Let’s check out the problems of ebike.
1.Swelling Of The Battery Pack
2.The battery Isn’t Charging
3.Battery Losing Its Efficiency
4.Ebike Not Speeding Up
5.Ebike Not Turning On
6.Takes Longer Time To Charge
1. Swelling Of The Battery Pack
Problem:
Lithium-ion batteries provide power through a chemical reaction. As the battery cell gets old, this reaction mechanism no longer entirely completes, which might cause gas to be released and cause the battery to swell.
Solution:
When batteries get swollen, they are no longer functional and you must replace them. Old, worn-out, or defective batteries may be to blame for the battery failure.
As a result of a considerable amount of the electrolyte inside the batteries evaporating, they may have overheated if they were old or had undergone numerous discharge and recharge cycles.
When the electrolyte is depleted, the batteries can overheat. The electrolytes help to keep the battery packs cool during recharging. The batteries may possibly contain an internal short circuit as a result of an earlier accident or rough handling, which has led them to overheat while receiving a recharge.
It’s less likely, but still conceivable, that the charger has a problem and is producing an excessive amount of voltage. You can test the battery charger’s output voltage to see if it meets standards. For each battery it charges, the charger’s output voltage should be close to 13.8 Volts.
Batteries shouldn’t overheat if the charger’s float cycle malfunctions and it continued to run on charge mode after the batteries had fully charged since this voltage of the battery pack and the charger’s output voltage would equalize and both would stay at a safe level.
2. Battery Isn’t Charging
Problem:
If the battery in your e-bike isn’t charging, there may be a number of possible causes, including a switch on the charger, a bad charger or charging port, or a problem with the battery itself. While many problems may be fixed, some could cost you buying a new charger or battery.
Solution:
If your ebike battery isn’t charging, you should look for the issues below.
Check if the electrical outlet is providing electricity
Check all the switches
Check the charging port
Check the charger
If you’re still unable to solve the issue then it’s possible that the battery’s BMS has problems or your battery is fully discharged.
If the battery is fully discharged then it will take some to start charging. If the problem still occurs then there is a high chance that the battery is fully damaged.
3. Battery Losing Its Efficiency
Problem:
The typical lifespan of lithium-ion batteries is 700-1000 charge cycles. Over this threshold, they typically start to lose their original charge capacity.
Solution:
If your battery is discharging quickly, there may be a short circuit somewhere, or you may be working with a battery that is defective. Both of these scenarios are possible.
You can determine what the problem is with the electric bike by removing the batteries and charging them on a bench before reattaching them to the bike.
If the battery is able to keep a charge, the issue is with your electric bike, and the likely culprit is faulty wiring or a short in the motor. If the battery is unable to maintain its charge, either one of the lithium-ion cells within is defective or there is a short circuit.
4. Ebike Not Speeding Up
Problem:
There might be other reasons which lead ebike to not speed up as usual. However, the battery is the prime reason for not getting the proper speed up.
Solution:
If your electric bike won’t start, check the main switch and the fuses. If the main switches and the fuses are fine then check the speed controller. Water dropping might damage your bike’s speed controller.
Also, check all the cables to your battery especially if you ride an electric bike on mountains and dirt roads. Because these types of bumpy roads might damage the connections.
5. Ebike Not Turning On
Problem:
When you push the power button, your bike might not turn on due to a low charge or a loose battery connection.
Solution:
If you’re facing such issues then you must check your battery and connectors by removing it. You may follow radpower’s technique to check the battery and connectors.
6. Takes Longer Time To Charge
Problem:
Either you’re using a less amp charger or your charger has lose efficiency that’s why it’s taking much more time to be fully charged.
Solution:
Before using any charger you should check if it’s provided by your manufacturer. You shouldn’t use any other charger than your provider.
If you’re using a manufacturer-provided charger and suddenly you’re facing such an issue then it’s possible that your charger is getting damaged and you need a new one.
Why Is The ChamRider Battery Not Charging?
If the charger malfunctions, a ChamRider e-bike battery may stop charging. Additionally, it occurs when a battery’s charging is stopped by a battery management system (BMS) due to security concerns. On top of that, it may happen if the battery runs out of power.
How Do You Check A ChamRider Battery?
A ChamRider ebike can be checked like all other ebikes. The most reliable way to check the battery’s health is to use a multimeter.
Conclusion
Maintaining your battery should be your first job as an ebike enthusiast. Now that you know the problems of e-bike batteries, surely now you will be able to better care for your battery. Besides, now you can easily troubleshoot battery problems without help from a professional.

Battery Management System (BMS) is a technology specifically designed to monitor battery packs, which are organized electrically in an x-by-y matrix configuration to achieve desired voltage and current ranges for expected load scenarios.
The supervision provided by BMS typically includes:
1. Monitoring the batteries
2. Providing battery protection
3. Estimating the operational state of the batteries
4. Continuously optimizing battery performance
5. Reporting operational status to external devices
The overall goal of BMS is to optimize battery performance through intelligent management and protection, thereby extending battery life.
Types of Battery Management Systems
There are different types of battery management systems, each with its unique features and applications.
Some common types of battery management systems include:
1. Centralized BMS Architecture
2. Modular BMS Topology
3. Master/Slave BMS
4. Distributed BMS Architecture
Centralized BMS Architecture
A centralized BMS is a system where all battery management functions are handled by a single computer. Such systems are typically used in large-scale commercial applications where reliability and accuracy are primary considerations.
Modular BMS Topology
Modular BMS topology is a BMS that utilizes modules connected to the batteries. These modules can be placed at any location on the battery pack, allowing for easy addition or removal of functionalities as needed. Modular design also facilitates easy upgrades or replacement of components without impacting the overall operation of the system.
This topology is particularly suitable for applications that require a high level of flexibility and scalability.
Primary/Subordinate BMS
Primary/Subordinate BMS is a configuration where one master unit controls and communicates with multiple slave units. The master unit coordinates the overall operation of the system, while the slave units handle specific tasks or monitor individual battery modules. This configuration allows for distributed control and monitoring while maintaining centralized coordination.
Distributed BMS Architecture
Distributed BMS architecture is a system where each battery module has its own local BMS, and these local BMS units communicate with each other to collectively manage the battery pack. This architecture allows for a decentralized approach to battery management, providing redundancy and fault tolerance.
This topology is particularly well-suited for applications that require high levels of flexibility and scalability.
The importance of Battery Management Systems
One of the most critical features of any electronic device is its battery. Without a reliable and robust battery, your device is essentially of little value—it might not even turn on!
While electronic devices continue to become more powerful and efficient, batteries have not necessarily become smaller or stronger. In fact, a study found that smartphone batteries have actually been getting larger in recent years!
Hence, the popularity of Battery Management Systems (BMS) among electronic manufacturers should come as no surprise. BMS plays a crucial role in ensuring that the batteries in electronic devices have the longest possible lifespan and reliable performance.
Functional safety
Lifespan and reliability
Performance and range
Troubleshooting and maintenance
Reliability
Cost and warranty reduction
Functional Safety:
A battery management system (BMS) can help to ensure that batteries in electronic devices last as long and perform as reliably as possible. This is important because it reduces the chances of accidents – not just with the device itself, but also with related equipment.
Life Span and Reliability:

Overall, using a BMS can result in cost savings for device manufacturers as well as end users. This is because it can help to reduce the number of battery packs that need to be manufactured (and/or purchased), as well as the associated expense. Additionally, a BMS can also provide additional warranty protection for devices.
The Battery Management System (BMS) serves several different functions. The Electrical Protection Management of the BMS helps protect the battery pack from overcharging, incorrect charging, and over-discharging. Capacity management assists in optimizing the battery pack's discharge voltage and capacity by monitoring charging/discharging cycles and adjusting battery parameters accordingly. The Thermal Management System (TMS) prevents thermal runaway of the battery by monitoring battery voltage, current, temperature, and fan speed.
Electrical Protection Management - Current:
BMS helps protect the battery pack from overcharging, incorrect charging, and over-discharging. Essentially, these management system functionalities help optimize battery performance by monitoring charging/discharging cycles.
Electrical Protection Management - Voltage:
One of the key functions of the BMS is voltage management. By monitoring the battery pack voltage levels and adjusting battery parameters (e.g., battery voltage) accordingly, the BMS helps prevent over-discharging or undercharging of the battery. This helps maintain optimal pack health and performance.
Thermal Management:
Thermal management is another important function of the BMS. By monitoring battery voltage, current, temperature, and fan speed, the BMS helps prevent thermal runaway of the battery. The thermal management system functionality also helps optimize battery pack performance by ensuring that the battery stays within safe operating limits.
Capacity Management:
BMS also assists in managing the capacity of the battery pack by monitoring charging/discharging cycles and adjusting battery parameters accordingly. This helps optimize battery performance while keeping the battery pack within a safe operating range.
Components of Battery Management System:
The Battery Management System (BMS) is a specialized hardware and/or software device that helps optimize the performance and lifespan of battery packs in electronic devices.
A typical BMS monitors the health (and condition) of individual batteries as well as the entire battery pack. It also provides accurate information on State of Charge (SOC), state of health, energy usage, and temperature of the battery. This makes it an essential tool for device manufacturers who want to ensure that their devices operate reliably even under harsh conditions.
In addition to improving device operation, the BMS also simplifies maintenance procedures. This is because it helps identify and diagnose issues early, minimizing the time and effort required to rectify problems.
Battery Management System (BMS) Operations and Maintenance
The Battery Management System (BMS) is a computer system that monitors, manages, and maintains battery charging, discharging, and status. The BMS can also predict when a battery may need replacement or repair.
BMS should be installed in any facility that uses or stores batteries, such as factories, power plants, hospitals, and schools. Having a BMS is crucial because batteries are critical components of many devices, from electric vehicles to mobile phones, and improper management can pose safety risks.
The primary goal of the BMS is to maintain battery health and safety by monitoring the battery's charge level, temperature, and other performance indicators. It also provides warnings to users when the battery starts to lose capacity or approaches its maximum limits. Additionally, if the battery requires maintenance or replacement, it can initiate preventive maintenance procedures.

Types of Battery Management Systems
There are different types of battery management systems, each with its unique features and applications.
Some common types of battery management systems include:
1. Centralized BMS Architecture
2. Modular BMS Topology
3. Master/Slave BMS
4. Distributed BMS Architecture
Centralized BMS Architecture
A centralized BMS is a system where all battery management functions are handled by a single computer. Such systems are typically used in large-scale commercial applications where reliability and accuracy are primary considerations.
Modular BMS Topology
Modular BMS topology is a BMS that utilizes modules connected to the batteries. These modules can be placed at any location on the battery pack, allowing for easy addition or removal of functionalities as needed. Modular design also facilitates easy upgrades or replacement of components without impacting the overall operation of the system.
This topology is particularly suitable for applications that require a high level of flexibility and scalability.
Primary/Subordinate BMS
Primary/Subordinate BMS is a configuration where one master unit controls and communicates with multiple slave units. The master unit coordinates the overall operation of the system, while the slave units handle specific tasks or monitor individual battery modules. This configuration allows for distributed control and monitoring while maintaining centralized coordination.
Distributed BMS Architecture
Distributed BMS architecture is a system where each battery module has its own local BMS, and these local BMS units communicate with each other to collectively manage the battery pack. This architecture allows for a decentralized approach to battery management, providing redundancy and fault tolerance.
This topology is particularly well-suited for applications that require high levels of flexibility and scalability.
The importance of Battery Management Systems
One of the most critical features of any electronic device is its battery. Without a reliable and robust battery, your device is essentially of little value—it might not even turn on!
While electronic devices continue to become more powerful and efficient, batteries have not necessarily become smaller or stronger. In fact, a study found that smartphone batteries have actually been getting larger in recent years!
Hence, the popularity of Battery Management Systems (BMS) among electronic manufacturers should come as no surprise. BMS plays a crucial role in ensuring that the batteries in electronic devices have the longest possible lifespan and reliable performance.

It is important to understand that not all electric bicycles are the same, and you should inspect the battery before use.If you are interested in purchasing a used electric bicycle, you may also want to check the health of the electric bicycle battery.
This article will guide you on how to quickly inspect an electric bicycle battery in the shortest possible time.
Want to know how to check an electric bicycle battery?
There are five steps you need to complete to thoroughly inspect your electric bicycle battery:
Step 1: Charge the battery and remove it from the bicycle for preparation.
First, you must fully charge the battery. Afterward, remove the battery from the bicycle.
Step 2: Perform a battery load test using a multimeter.
To check the battery voltage, set the multimeter to the DC mode.
Step 3: Check the multimeter for accurate voltage.
If a negative reading appears during the measurement, the polarity of the probes is reversed.
Step 4: Test the current.
Compare the current reading generated by the multimeter with the battery's user manual. This will give you an idea of how the battery capacity should compare to its current capacity.
Step 5: Perform a resistance test.
Finally, use the multimeter to measure the resistance of the battery. Resistance is the attempt to impede the flow of current through the battery. If the resistance is too high, the battery may overheat.
What tools do you need to test an electric bicycle battery?
The only tool you need is a multimeter to test your electric bicycle battery. A multimeter is a versatile and readily available tool for electrical measurements. They come in digital and analog variants, and can be obtained online or at any hardware store.
But what does a multimeter actually measure? It measures electrical quantities such as current, voltage, and resistance, among others, for batteries and other electrical components. More advanced multimeters may also test other types of values.
However, performing a simple battery test on your electric bicycle doesn't require those additional capabilities.
Typically, analog or digital multimeters are handheld devices with two probes. You should place the black probe on the battery terminal that corresponds to the negative end, and the red probe on the positive end when using the electric bicycle battery.
What are the signs of a bad battery?
With indicators, you can assess whether the battery in an electric bicycle is in good condition and whether a specific electric bicycle battery purchase is worth it.
What parameters of the electric bicycle battery are you testing?
Whenever we talk about testing an electric bicycle battery, we mean testing the battery's voltage, current, and resistance.
What voltage should I look for on the multimeter?
For a battery with a rated voltage of 36 volts, the ideal range displayed on the meter is 28 to 36 volts. You can adjust this factor to fit the specific voltage of your electric bicycle. In general, if your reading is 10 volts or lower than the value specified in the manual, the voltage is too low and not recommended.
For a 52V battery pack, the measured voltage typically ranges between 58VDC and 42VDC. A 48V battery pack will produce voltages between 54VDC and 40VDC. However, measuring is just an estimate as evaluating any battery model requires considering many factors.
