The 36V 29Ah battery is ready to be installed in the rear rack of any bike. It included rear position light and some space to keep things inside!!

🔋this battery has a raw maximum discharge current of 100A continuously (3kW) and 200A peaks (6kW) although for its use (a 600W electric bike) it is just paired enough with a 30A continuous limit BMS🔋
