48V 20Ah Downtube E-Bike Battery – 960Wh High Capacity Lithium Pack

The 48V 20Ah Downtube E-Bike Battery is a high-energy lithium pack built for powerful e-bike systems that require strong output and extended riding range. Delivering 960Wh of stored energy, this battery is ideal for long-distance riding, cargo builds, and higher-performance electric bike setups.

Constructed using high-density 21700 lithium cells, the pack provides stable voltage and consistent discharge performance. A built-in smart BMS (Battery Management System) protects against over-charge, over-discharge, over-current, short circuit, and temperature issues, ensuring safe and reliable operation.

The downtube mounting design keeps weight centred within the frame for improved balance and handling compared to rear rack batteries. The integrated housing gives a clean, factory-style look while remaining removable for convenient charging.

With a cycle life of up to 1000 charge cycles, this battery is designed for regular use and long service life.
