Product Overview:

  • 3S Battery Configuration: This BMS is specifically designed for a 3S lithium-ion battery pack, which includes 3 cells connected in series to achieve a nominal voltage of 11.1V and a fully charged voltage of 12.6V. It ensures optimal performance and longevity for your 18650 battery pack.
  • Maximum Current: The module can support continuous discharge currents up to 10A, making it suitable for powering devices or projects that require moderate to high current.
  • Battery Protection: The BMS provides crucial protection functions to prevent damage to the batteries and ensure safe usage:
    • Overcharge Protection: Prevents the battery from being charged beyond its safe voltage, which could otherwise lead to overheating or cell damage.
    • Overdischarge Protection: Prevents the battery from being discharged below its safe voltage, which could cause capacity loss or permanent damage to the cells.
    • Overcurrent Protection: Protects the battery pack from excessive current that could damage the cells or cause heat buildup.
    • Short-circuit Protection: Cuts off the power supply in case of a short circuit, preventing potential hazards.
  • Voltage Monitoring: The BMS monitors the voltage of each individual cell in the pack, ensuring balanced charging and preventing voltage imbalances that could shorten battery life.
  • Compact Design: The module is small and lightweight, making it easy to integrate into various DIY electronics projects, such as building battery packs for electric bikes, drones, or solar storage systems.
  • Heat Dissipation: The BMS is designed to dissipate heat efficiently, ensuring safe and reliable performance even under high loads.
