BMS for 10S/36V ebike Dorado battery with mini size 65x35x9mm/with ON/OFF switch

Availability: In Stock


Brand: GBK


Quick Overview

BMS for 36V Li-ion ebike battery with countinuous discharge current being 20A. This BMS is small in dimension(L*W*H: 65*35*9mm) which you can install it into many different battery cases. If you want to make a 5V output for charging your mobile or ipad, you can add a 5V1A USB PCB when ordering the PCM.

The battery BMS has a ON/OFF switch, if you don't have swtich for your battery, you can just solder the two switch wires together.

The battery BMS also has a high temperature protection sensor; if the battery is too high in temperature, the BMS will cut off power to protect the battery.



PCM for ebike lithium ion 36V battery with continous discharge current being 20A. The pulse discharging current is 40A. The BMS has ON/OFF switch, if you don't need ON/OFF switch for your battery, you can short circuit the on/off switch. If you want to make a 5V USB output from the battery, you can add a 5V1A USB output PCB when ordering the BMS.
