The TDT NMC 7S 40A Hardware BMS

(Battery Management System) is designed for 7-series (7S) lithium-ion / NMC battery packs, ensuring safe, stable, and efficient battery operation. This hardware-based BMS supports up to 40A continuous discharge current, making it ideal for e-scooters, e-bikes, portable power packs, and small EV or energy storage applications.

Equipped with advanced protection circuits, the TDT 7S 40A BMS safeguards the battery against over-charging, over-discharging, over-current, short circuit, and cell voltage imbalance, helping extend battery life and improve overall system reliability. Its hardware-based design ensures fast response, high accuracy, and long-term durability.

This BMS is compatible with NMC lithium-ion cells and is widely used in custom battery pack manufacturing, OEM assemblies, and replacement battery systems.
