Description:
The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection, balanced protection etc.
The PCB use high anti-corrosion, dustproof and dampproof coating, protect stable performance, prevent short circuit, oxidation and corrosion. The consumption of the whole device is less than 50mA.
Note:
This version is compatible with battery pack of 7S to 20 strings.
BMS compatible with battery pack: 7S 8S 10S 12S 13S 14S 15S 16S 17S 18S 19S 20S
Please note: The appearance of this product has been upgraded, the size of the old version is 165*115*76mm, and the size of the new version is 200*115*52mm. Other functions remain unchanged. We will update the pictures as soon as possible. thank you for understanding.
