3S 100A LiFePO4 Lithium Battery Protection

Dedicated 3-Series (3S) LiFePO4 Protection: Tailored specifically for 3-cell lithium iron phosphate (LiFePO4) battery packs operating at nominal 9.6V and peak 10.8V - 10.95V charging voltage.

100A Continuous High-Current Output: Delivers up to 100A continuous discharge current with high thermal stability, engineered for high-demand energy storage systems and heavy DC loads.

Integrated Passive Cell Balancing: Features built-in voltage equalization circuitry during charge cycles to keep all three LiFePO4 cells strictly balanced, extending total battery lifecycle.

Multi-Layer Automated Safeguards: Provides hardware-level cutoffs against overcharging, over-discharging, overcurrent, and short circuits to ensure safe battery operation.

Heavy-Duty Heat Dissipation Design: Built on a thick copper trace PCB layout equipped with low internal resistance power MOSFETs for cooler operation under high discharge rates.

Board Material: High-grade FR-4 glass-reinforced epoxy PCB with high-power SMT MOSFETs and passive balance resistors.

Technical Specifications:

Series Configuration: 3S LiFePO4 (3 Cells in series).

Nominal / Charge Voltage: 9.6V nominal / 10.8V - 10.95V max charge voltage.
