BMS LFP 4S 80A JBD (ZP04S014) (7jjs)

BMS LFP 4S 80A JBD (ZP04S014) is a hardware battery management system designed for 4S LiFePO4 (12.8V) battery packs. It supports 80A continuous discharge, built-in cell balancing, and advanced safety protections including over-charge, over-discharge, over-current, short circuit, and temperature protection. Suitable for solar batteries, e-bikes, UPS, inverters, and energy storage systems.

The BMS LFP 4S 80A JBD (ZP04S014) is a reliable hardware battery protection board developed for 4-series LiFePO4 battery packs (12.8V nominal). It monitors the voltage, current, and temperature of each cell to maintain battery safety and extend battery lifespan.

This BMS provides 80A continuous discharge current capability and supports high current loads used in electric vehicles, solar energy storage systems, portable power stations, and backup power solutions. The board uses a common port design, meaning charging and discharging share the same port, making wiring easier and reducing installation complexity.

It includes passive cell balancing (approximately 150–250mA) to keep all battery cells at equal voltage levels, improving battery performance and preventing cell imbalance during charging cycles.
