Overview: 3S 12.6V 60A Li-Ion Cell BMS Charging Protection ModuleThe 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.Product Visual: 3S 12.6V 60A BMS Module – PhotoKey Protections and How They WorkOvercharge 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 SpecificationsDesigned for 3S (12.6V) Li-Ion / Li-Po battery packsContinuous discharge current: up to 60APeak cutoff current: around 80A (typical)Overcharge cutoff voltage: ~4.25 ±0.05V per cellOver-discharge cutoff voltage: ~2.7 ±0.1V per cellSupports cell balancing for stable pack performanceOperating temperature range: -20°C to 60°CSturdy PCB design suitable for high-load useCompatible with CC/CV Li-Ion chargersApplicationsHigh-power DIY battery packs and battery assembliesElectric bikes, scooters, hoverboards, and personal mobility devicesSolar energy storage and off-grid power systemsDrones, robotics, automation, and high-drain IoT projectsPortable power stations, inverters, and backup systemsInstallation and Wiring TipsFollow 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 CompatibilityDesigned 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.If you need wiring diagrams, BMS pinouts, or help choosing a compatible charger or fuse, contact our support team with your battery pack details and expected load profile.
