4S 100A BMS Battery Protection Board with Balance 12.8V 14.8V

The HX-4S-F100A is a high-power 4S 100A BMS (Battery Management System) designed to monitor, balance, and protect your 4-cell lithium battery packs. Whether you are building a 12.8V Lithium Iron Phosphate (LiFePO4) pack or a 14.8V Lithium-Ion (Li-ion) pack, this heavy-duty protection board ensures optimal performance and safety. It handles an impressive continuous discharge current of up to 100A, making it the ultimate choice for high-demand DIY projects, electric vehicles, and power storage systems.

Equipped with an integrated active equalization circuit, this BMS balances individual cell voltages during charging to maximize the overall capacity and lifespan of your battery pack. It features robust safety mechanisms, including overcharge, over-discharge, overcurrent, and short-circuit protection. The onboard aluminum plate heatsink provides excellent thermal dissipation, ensuring stable operation even under continuous heavy loads in solar energy storage systems, E-bikes, and custom power walls.

Features:

• High Current Capacity: Supports up to 100A continuous discharge current, ideal for high-power motor drives and inverters.
• Integrated Cell Balancing: Onboard equalization circuit delivers 50mA to 60mA of balancing current to keep cells healthy and evenly charged.
• Dual Chemistry Compatibility: Highly versatile board suitable for both 3.2V LiFePO4 (12.8V nominal) and 3.7V Li-ion (14.8V nominal) battery configurations.
• Robust Thermal Management: Features a thick aluminum plate heatsink to prevent overheating during high-current operations.
• Comprehensive Protection: Built-in safeguards against overcharging, over-discharging, overcurrent, and short circuits.
• Easy Wiring: Comes with a high-quality 5-pin JST connector cable for straightforward voltage monitoring and balance wiring.
