E-bike Range Extender 36V 360Wh 10Ah new, Samsung 50E 5000mAh cells tested before and after construction. BMS electrically protected and with Bluetooth connection. Charger, wiring diagram, installation kit, and instructions are also provided. I have more than one available; there may be small differences, but the power and dimensions are always the same. Compatible with Shimano, Yamaha, Brose, Bafang, Oli, etc. systems. For Bosch and Fazua, a small modification to the battery is required. I can perform the installation and battery modification upon agreement.
