BMS Module 13S 48V 35A – Protection and Balancing for 18650 Li-Ion Batteries
This BMS (Battery Management System) module is designed for 13S 48V Li-Ion batteries, making it ideal for electric scooters, electric bicycles, and electric motorcycles. It ensures complete protection and active cell balancing for maximum efficiency and extended lifespan.
The module manages each cell individually, equalizing the voltages during charging and discharging. If a cell’s voltage differs by more than 0.1V from the others, it is automatically discharged to maintain balance across the entire pack.
