LiFePO4 2S 10A Balanced BMS Battery Charging Protection Module for 6.4V Lithium Iron Phosphate Packs

The LiFePO4 2S 10A Balanced BMS Battery Charging Protection Module is an essential power management component for lithium iron phosphate (LiFePO4) battery packs. It ensures safe charging, discharging, and balancing for 2-cell (6.4V) battery configurations. This module is perfect for DIY energy storage systems, solar power banks, portable devices, and e-bike battery packs requiring stability and protection.

Built with advanced MOSFET control circuitry, this BMS (Battery Management System) protects batteries from common electrical faults such as overcharge, over-discharge, overcurrent, and short-circuits. It helps extend the life of LiFePO4 cells by maintaining balanced voltage levels between cells, preventing uneven wear and enhancing performance.

Working Principle of LiFePO4 2S BMS

The LiFePO4 2S 10A BMS module operates by monitoring the voltage and current of each individual cell in a 2S pack.

• When the charging voltage exceeds 3.65V per cell, it cuts off charging to prevent overcharging.

• When the discharge voltage drops below 2.0V per cell, it stops the load to prevent deep discharge.

• During charging, it balances the cells by diverting current from higher-voltage cells until all reach an equal voltage level.

This ensures each cell remains healthy and evenly charged, maintaining long-term battery efficiency and lifespan.
