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.

Key Features and Specifications

Applications

  • High-power DIY battery packs and battery assemblies
  • Electric bikes, scooters, hoverboards, and personal mobility devices
  • Solar energy storage and off-grid power systems
  • Drones, robotics, automation, and high-drain IoT projects
  • Portable power stations, inverters, and backup systems

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.
