Condition: New – Open box
The BMS-1106 / 311077 Battery Protection Board is a dedicated management circuit built for 3S and 4S Li-ion and LiFePO₄ battery packs, delivering reliable protection against overcharging and overdischarging. This BMS module monitors cell voltage levels across the pack and steps in to prevent conditions that would otherwise degrade cell health or create unsafe operating states, making it a practical choice for anyone assembling or maintaining a custom battery pack.
For builders working on electric bicycle battery packs, solar energy storage systems, or other portable power setups, this 3S/4S BMS module addresses a common pain point: keeping individual cells balanced and safe without manual oversight. By actively guarding against overcharge and overdischarge conditions, the board helps extend overall battery lifespan and reduces the risk of premature cell failure. Its compatibility with both Li-ion and LiFePO₄ chemistries gives users flexibility when designing packs for different voltage and capacity requirements, whether for a DIY power bank, an e-bike conversion, or a small-scale solar storage bank.
This lithium battery protection board is best suited for hobbyists, technicians, and small-scale system integrators who need dependable cell protection circuitry for 3S or 4S configurations. Anyone searching for a BMS protection board to pair with Li-ion or LiFePO₄ cells will find the BMS-1106 / 311077 a straightforward component for adding safety and longevity to a custom battery build.
