The BMS NMC 13S 40A (ZP16S011) (548b) is a high-performance battery management system specifically designed for 13-series lithium-ion/NMC batteries (13S). With a nominal voltage of approximately 48.1V and a maximum fully charged voltage of 54.6V, this BMS ensures safe and efficient battery operation under a wide range of conditions. Rated for continuous charge and discharge currents of 40A, it is suitable for medium- to high-power applications such as electric scooters and electric bicycles.

This BMS offers comprehensive protection for each cell and for the overall battery pack. Its safety features include:

• Overvoltage protection to prevent exceeding safe charging limits.
• Undervoltage (overdischarge) protection to prevent damage from deep discharge.
• Overcurrent and short-circuit protection.
• Temperature monitoring to protect cells from overheating.

The board also integrates passive cell balancing, ensuring that each cell maintains optimal voltage, preventing premature capacity loss and enhancing the overall battery lifespan.

The compact and lightweight design makes it easy to integrate into DIY battery packs and small electric vehicles, with simplified wiring that reduces installation complexity.
