MAXKGO Smart BMS Board 24S 70A Lithium Battery Charging Protection Board For E-scooter / E-car / E-bike-/ E-skateboard

MAXKGO BMS (Battery Management System) is designed specifically for electric skateboards, onewheels, and other electric vehicles utilizing VESC (Vector Electronic Speed Controller) technology. This smart BMS ensures optimal performance and safety by monitoring critical parameters such as voltage levels, current flow, and temperature of each individual cell within the battery pack.
