52v 20ah

50V 20Ah Lithium E-Bike Battery — 30A BMS | 3A Fast Charger | Up to 1500W

Unlock more power, range, and reliability. The 50V 20Ah Lithium Battery is a high-output, plug-and-play upgrade designed for riders who demand consistent performance and extended runtime from their e-bike or scooter setup. Perfect for mid-drive and hub-motor systems up to 1500W, this battery delivers stable power with the efficiency and safety serious riders expect.

Each pack is built with premium 21700 lithium cells, selected for their high energy density and low internal resistance. The integrated 30A Battery Management System (BMS) actively balances and protects each cell, providing real-time safeguards against over-current, over-charge, over-discharge, and temperature spikes.

The result: cleaner power delivery, longer cycle life, and stronger acceleration across the entire charge curve.

Every battery includes a 3A smart fast charger that reduces charge time without sacrificing battery health. The rugged hard-shell case features a lock-and-key mount, LED power indicator, and slide-rail base for easy installation and removal. Whether you’re upgrading your stock system or building a custom e-bike, this 50V powerhouse gives you the confidence to push further.
