    Description

    A 6S 18650 Lithium Battery BMS (Battery Management System) Protection Board is a circuit board used to safely manage a battery pack made from six 18650-sized lithium-ion cells connected in series. The “6S” specifies the series cell count, which results in a nominal voltage of 22.2V and a full charge voltage of 25.2V for standard lithium-ion cells.

    Features:

    • Protection functions: A primary function of a BMS is to protect the lithium cells, which are sensitive to improper charging and discharging.
      • Overcharge protection: Prevents cells from being charged to an unsafe voltage level, which can damage the battery and pose a fire risk.
      • Over-discharge protection: Stops the battery from discharging below a minimum safe voltage, which can cause permanent damage to the cells.
      • Overcurrent protection: Guards against excessively high discharge current, which can overheat the battery.
      • Short-circuit protection: Shuts off the battery immediately if a short circuit is detected.
    • Cell balancing: Some BMS boards include a balancing feature that ensures all six cells in the pack are charged to the same voltage. This helps maximize the battery’s lifespan and performance.
    • Application compatibility: 6S BMS boards are used in various applications, including DIY battery packs for power tools, electric bikes, and solar lighting systems. The specific BMS you need depends on the current draw of your application.

    Important considerations:
    • Safe handling: When working with 18650 batteries and BMS boards, it is crucial to have professional operating knowledge due to the risk of fire or damage from improper use.
    • Wiring accuracy: Incorrect wiring is a common issue. Before connecting the BMS, you should always check the voltage detection wire order.
    • Initial activation: After the first connection, some BMS boards require a suitable charger to be connected for a few seconds to activate the output. 

    Applications:

    • Battery pack
    • Power supply
    • Power bank and charger
