4S 100A BMS Protection and Balancing Board for Lithium Iron Phosphate (LiFePO4) Batteries

A powerful 4S protection and balancing board (BMS) designed specifically for lithium iron phosphate (LiFePO4) batteries with a working current of up to 100A. The controller continuously monitors the state of each cell, protecting the pack against overcharging, critical voltage drop, overcurrent and short circuit. The integrated balancing function equalizes the charge level between cells, preventing imbalance and significantly extending the service life of the entire battery. Features: Product type: protection and balancing board / BMS controller (BMS Board / Battery Management System) Specifications: 4S configuration (for 4 cells of LiFePO4 connected in series), rated/maximum working current 100A, built-in cell balancing function, powerful power MOSFET transistors Purpose: comprehensive protection of battery packs against overcharging, deep discharge and short circuit, and voltage equalization across cells
