The 52V platform delivers more power and range than 48V for the same amp-hour rating, and the VISET LI 52V 20Ah is a high-capacity option in the 52V class. Its 1040Wh rating combined with a 40A BMS make it a versatile and reliable option for riders looking for either a casual commute or a high-power conversion build. It has a mounting bracket and includes a key lock, an LED battery status light and a USB charging port for convenience.
VISET LI is a manufacturer of ebike batteries, offering multiple configurations in terms of voltage and capacity. The VISET LI 52V 20Ah battery is intended for riders seeking more than a typical 48V system, and is marketed as a battery for both ebikes and scooters. The 52V nominal voltage of this battery results in approximately 8 percent more power compared to a 48V battery of equal capacity, and thus may produce faster top speeds and improved hill climbing performance dependent upon the configuration of the rider's controller and motor.
Specs and Value
The 52V nominal and 20Ah specs of the battery provide a total of 1040Wh of energy storage. The 40A BMS provides overcharge protection, over-discharge protection, short circuit protection and overcurrent protection. VISET LI recommends this battery for use with motors ranging in size from 200W to 2000W, providing a broad range of motor compatibility that is not typically found in a battery offered at such a low cost.
Physical specs
The physical dimensions of the battery are 14.5 x 3.54 x 5.01 inches, which is a common downtube design for ebike batteries. The battery includes a bracket that attaches to water bottle screw holes in the bike frame, and thus can be installed on nearly all types of bikes. The included charger is a 58.8V 2A charger that will require approximately 10 to 12 hours to completely charge the battery from an empty state. While this is a relatively slow rate of charging, it is sufficient to allow for overnight charging between rides.
There are several features that distinguish the VISET LI 52V 20Ah from other battery products. The battery includes a USB port, allowing riders to charge their phone or other devices while riding, which is a feature that many riders consider to be quite useful. Additionally, the on/off switch can help reduce power consumption when the battery is not in use, and the LED battery indicator provides a simple method to quickly determine the battery's remaining charge without having to turn on the bike display.
BMS and motor range
The 40A BMS that is used in this 52V battery system theoretically provides for a maximum output of approximately 2080 watts, which should provide more than sufficient power for the recommended motor size range of 200W to 2000W. VISET LI describes their cells as automotive grade and states that the cell-to-cell connections are made of pure nickel sheets. These characteristics suggest a focus on quality construction and potentially an extended lifespan for the battery. The manufacturer indicates that the battery will retain 80 percent or more of its original capacity after 800 charge and discharge cycles, which corresponds to more than two years of riding based on a single charge per day.
The battery includes a shock-absorbing battery holder to protect the cells during rough riding conditions, which is a valuable feature that not all battery manufacturers include. Less vibration and shock applied to the cell-to-cell connections may contribute to extending the lifespan of the pack.
Form Factor and Compatibility
The battery is designed with a mounting bracket that attaches to the water bottle screw holes in most bike frames. The bracket securely holds the battery in place and includes a key lock to prevent theft. This is one of the most widely-compatible mounting solutions available for aftermarket ebike batteries.
Before purchasing, confirm that your ebike controller is capable of handling a 52V input. Some 48V controllers are only capable of handling voltages up to 48V, and connecting a 52V battery to a 48V-only controller may cause damage to the controller. If your controller is rated for 48V to 52V compatibility (often labeled as 48V/52V compatible), then this battery will function properly. However, if your controller is strictly 48V, it would be wise to choose a different battery.
The motor compatibility of this battery spans from 200W to 2000W, and it is therefore suitable for use with virtually any type of hub motor, as well as for conversion builds that utilize mid-drive motors like the Bafang BBSHD.
Real-World Range
Based on the total capacity of 1040Wh, this battery has one of the highest capacities available in a non-dual battery configuration. Assuming a 750W motor with moderate pedal assistance and riding on flat terrain, the expected range is approximately 40 to 55 miles per charge. Using a 1000W or 1500W motor and applying heavy throttle on mixed terrain, expect the range to be approximately 25 to 40 miles per charge. Although the 1040Wh capacity may not support a full ride with a 2000W motor, it will certainly support meaningful rides.
Daily commuters that travel 15 to 30 miles each way will likely be able to complete their full work week on a couple of charges. Due to the higher voltage of this system, the rider can achieve slightly more efficient use of their motor and receive a few extra miles of range per charge.

Who Should Buy This
The VISET LI 52V 20Ah is a solid recommendation for riders that desire the increased power and range of a 52V system and a 1040Wh capacity battery. The 40A BMS will support motors up to 2000W, the USB port provides an added layer of functionality, and the water bottle mount is compatible with a vast majority of bike frames. The key lock and LED indicator provide added convenience. The 1-year warranty and 7-day return policy provide added security for riders considering this battery.
This is not the right battery for riders that need a 48V or 36V battery, nor is it suitable for riders whose controller is not compatible with 52V input. If you need fast charging capabilities, the included 2A charger is a relatively slow charger for a 20Ah battery.
However, for riders that are searching for a well-protected 52V battery with desirable features at a competitive price per watt-hour, the VISET LI 52V 20Ah is an excellent option. Compare it to other options on our battery comparison table.
