- Maximum Charge Voltage: 12.6 V
- Continuous Discharge Current: 25 A
- Charge Current: Up to 12–15 A (typical)
- Cell Type: Li-ion / Li-polymer
- Balancing Method: Passive cell balancing
- Protection Functions: Over-charge, over-discharge, over-current, short-circuit
- Operating Temperature: −20 °C to +60 °C
Features:
- High current handling up to 25 A
- Integrated cell balancing for improved battery lifespan
- Multiple MOSFETs for stable and efficient power control
- Compact and lightweight PCB design
- Clear pad labeling for easy wiring
- Reliable protection against common battery faults
