MAXKGO VESC BMS smart BMS 12S 70A protection board for Ebike/Esk8/EScooter.ETC

MAXKGO-SS BMS is based on the modular BMS of LTC6811 and STM32 MCU. It is a full-featured battery protection board for electrical motorbike，light electric vehicles and electric skateboards. It is a smart mini BMS that integrates charging protection, discharge protection, temperature protection, passive balance.（The factory default setting is 24S. If you need to change it, please modify it yourself.）

Expertly designed, the MAXKGO smart BMS 12S 60V 70A protection board is compatible with both VESC and FSESC® systems. This smart BMS provides superior protection and efficiency for Ebikes, Esk8s, Escooters, and more. With advanced features including VESC compatibility, this BMS ensures maximum performance for all your electric transportation needs.

Firmware & software repositories are available on our- Github page.
