52V 14S Li-ion Battery Pack for E-Bike, Electric Scooter & Cargo Conversions – 13.5Ah / 15Ah with Bluetooth BMS
Power a compatible e-bike, electric scooter or cargo conversion with this 52V-class 14S Li-ion battery pack, available in 13.5Ah (13,500mAh) and 15Ah (15,000mAh) capacities. Both options use a 14S3P configuration with a 51.8V nominal voltage, a Bluetooth smart BMS and a 40A continuous discharge rating.
Check your battery's remaining capacity, current and individual cell-group voltages through Bluetooth monitoring before setting out, or follow the balancing process while maintaining your pack.
Capacity options
- 13.5Ah / 13,500mAh
- 15Ah / 15,000mAh
Both capacities share the same configuration, dimensions, weight, BMS and connections. Actual riding range depends on the conversion system, load, terrain, speed, assistance level and operating conditions; no fixed mileage is promised.
Compatibility and fit
Designed for suitable 52V-class e-bike, electric scooter and cargo conversion systems. The battery's nominal voltage is 51.8V and its fully charged voltage is 58.8V. Confirm that your controller and other electrical components support this voltage range and that their current requirements are within the battery's ratings.
This is not a universal fit or a confirmed replacement for every e-bike or electric scooter battery. Check the available mounting space, connector type and polarity before ordering. Allow space for the cables, connectors and a secure mounting arrangement.
