3S 4S 5S 100A 12V LiFePO4 BMS Protection Board

The 3S 4S 5S 100A 12V LiFePO4 Battery Protection Board is an industrial-grade battery management system (BMS) engineered for high-drain 3.2V Lithium Iron Phosphate battery packs. Equipped with high-power N-channel MOSFET switches and onboard precision balance circuitry, this BMS delivers up to 100A continuous discharge current while actively safeguarding your cells against overcharge, over-discharge, short-circuit, and high-current overload conditions. Its robust aluminum heat sink design provides effective thermal dissipation, preventing thermal runaway during peak discharge periods in demanding energy storage applications.

Ideal for DIY high-power battery packs, solar power storage systems, inverter setups, electric vehicles (EV), and high-output DC motor assemblies, this protection board offers versatile configuration jumper pads to operate cleanly across 3S, 4S, or 5S cell arrangements. It serves as an essential drop-in safety and cell-balancing module for 18650, 26650, 32650, and prismatic LiFePO4 chemistry builds, ensuring balanced cell voltages and extended pack cycle life.

Features:

• High Current Handling: Rated for up to 100A continuous discharge current with low-resistance MOSFET architecture.
• Multi-Cell Selectable Design: Configurable solder jumper pads for 3S, 4S, or 5S LiFePO4 cell arrangements.
• Integrated Active Balancing: Built-in individual cell balance circuitry maintains uniform cell voltages during the charging cycle.
• Complete Pack Protection: Reliable multi-stage protection covering overcharge, over-discharge, short-circuit, and overcurrent conditions.
• Enhanced Thermal Dissipation: Integrated aluminum backing heat sink ensures stable thermal dissipation under continuous load.
• Heavy-Duty Solder Terminals: Large contact pads for high-gauge wiring to minimize contact resistance and voltage drop.
