48V 18.2Ah Rear Rack E-Bike Battery – 840Wh High Capacity Lithium Pack

The Varstrom 48V 18.2Ah Rear Rack Battery is a high-energy lithium battery built for powerful e-bike systems that require strong output and extended range. Delivering 840Wh of stored energy, this pack is ideal for long-distance riders, cargo builds, and higher-performance electric bike setups.

Constructed using quality 18650 2600mAh cells in a 13S7P configuration (91 cells), the battery provides stable voltage and consistent discharge performance. A built-in 30A BMS (Battery Management System) protects against over-charge, over-discharge, over-current, and short circuits for reliable, safe operation.

The rear rack design keeps the bike’s frame triangle free while maintaining balanced weight over the rear wheel. A secure locking system holds the battery firmly in place, while the LED indicator allows quick checks of charge level at a glance.

The pack charges using a 54.6V 3A or 4A charger and offers a cycle life of up to 1000 charge cycles, making it suitable for regular daily use.
