4S 100A LiFePO4 BMS Protection Board – 12V / 14.4V High Current Battery Management System in Pakistan

Overview 

The 4S 100A LiFePO4 BMS is a professional-grade protection circuit designed specifically for 3.2V Lithium Iron Phosphate cells. In a 4-series (4S) configuration, it creates a 12.8V (nominal) / 14.4V (peak) battery pack—the perfect replacement for heavy lead-acid batteries. With a massive 100A discharge capacity, this board features a thick aluminum heat sink to dissipate heat, ensuring your DIY battery remains stable under heavy loads like inverters, motors, or solar charging systems.

Key Features 

• High Current Handling: Supports up to 100A continuous discharge, making it suitable for high-wattage DC appliances.

• Integrated Balancing: Features an “Equalization” circuit that ensures all 4 cells stay at the same voltage, significantly extending battery life.

• Multi-Layer Protection: Full safety suite including Over-charge, Over-discharge, Over-current, and Short-circuit protection.

• Robust Heat Dissipation: Equipped with a heavy-duty aluminum plate to keep the MOSFETs cool during high-current operation.

• Split Port / Common Port Design: (Note: Check specific stock, but usually supports common port for easy wiring).
