3S 12.6V 60A Li-Ion Cell BMS Charging Protection Module

Overview: 3S 12.6V 60A Li-Ion Cell BMS Charging Protection Module

The 3S 12.6V 60A Li-Ion Cell BMS Charging Protection Module is a high-power Battery Management System engineered for 3-cell Li-ion and LiPo battery packs. With a full-charge voltage of 12.6V and a 60A continuous discharge rating, this BMS protects and optimizes high-drain battery packs used in e-bikes, scooters, drones, robotics, portable power stations, and solar storage systems.

Key Protections and How They Work

• Overcharge Protection: Stops charging when any cell exceeds approximately 4.25V to prevent cell damage and thermal risks.
• Over-discharge Protection: Cuts output when any cell drops below about 2.7V to avoid deep discharge and irreversible capacity loss.
• Overcurrent Protection: Shuts down output if continuous discharge exceeds 60A; typical peak cutoff near 80A.
• Short-Circuit Protection: Immediate cutoff to protect the battery and connected load from catastrophic failure.
• Cell Balancing: Passive balancing keeps all three cells at similar voltages for improved efficiency and longer pack life.
• Automatic Recovery: The module will restore normal operation automatically once fault conditions clear, eliminating the need for manual resets in most cases.

Installation and Wiring Tips

• Follow proper cell order when connecting B-, B1, B2, B3 and pack positive terminals to avoid damage.
• Use appropriately rated wires and secure solder joints or connectors to handle continuous 60A current safely.
• Ensure a reliable connection to balance leads so the cell balancing function stays effective.
• Keep the BMS mounted on a flat, non-conductive surface with good ventilation to maintain operating temperature.
• Test under controlled conditions after installation to confirm protection thresholds and correct wiring.

Safety Notes and Compatibility

• Designed for Li-Ion and LiPo chemistries using CC/CV charging profiles. Do not use with NiMH or lead-acid batteries.
• Images are for illustration purposes only; check physical pinout and dimensions before final installation.
• Observe standard battery handling and charging safety practices to minimize risk of fire or injury.
