4S 12V 10A LiFePO4 BMS with NTC Sensors – Smart Battery Management System with 120A Protection & Cell Balancing

Stop worrying about battery failures — the 4S 12V LiFePO4 BMS is your all-in-one guardian that protects, balances, and extends the life of your LiFePO4 battery pack with intelligent, real-time management.

This Battery Management System is purpose-built for 4-cell (4S) LiFePO4 configurations with a 12.8V nominal voltage and up to 14.7V maximum charging voltage. It delivers 10A continuous charge/discharge current with a massive 120A peak overcurrent protection that kicks in within just 150ms — fast enough to shield your pack from sudden load spikes before any damage occurs. The ultra-low 30mΩ internal resistance ensures minimal energy loss, while the 40µA standby consumption means your battery won't self-drain during long storage periods.

What sets this BMS apart is its dual NTC thermal sensor system — automatically cutting off charging at 50°C (±5°C) and discharge at 70°C (±5°C), with self-recovery once temperatures normalise. Built-in passive cell balancing keeps all 4 cells in sync, preventing capacity drift and maximising overall pack lifespan. Whether you're building a solar storage system, e-bike battery, UPS backup, or portable power station, this BMS delivers the protection and reliability your application demands.
