5S 100A LiFePO4 Lithium Battery Protection

Dedicated 5-Series (5S) LiFePO4 Protection: Tailored specifically for 5-cell lithium iron phosphate (LiFePO4) battery pack configurations operating at nominal 16V and peak 18V max charging voltage.

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

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

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 Layout: Built on a heavy-duty PCB equipped with dual rows of low internal resistance surface-mount MOSFETs and an aluminum heat distribution plate 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: 5S LiFePO4 (5 Cells in series).

Nominal / Charge Voltage: 16V nominal / 18V max charge voltage.

Continuous Discharge Current: Up to 100A.

Balance Function: Yes (Integrated passive cell balancing).
