BMS NMC 17S 60A JBD (HP24SA) (66t6)

BMS NMC 17S 60A JBD (HP24SA) (66t6)

The JBD NMC 17S 60A BMS (model HP24SA / 66T6) is a robust smart battery management system engineered for ~63V lithium‑ion (NMC) battery packs. With support for 17 cells in series (17S), this BMS is ideal for medium‑to‑high power applications such as electric vehicles, solar energy storage systems, and UPS/backup battery installations.

Designed with advanced circuitry and safety features, the BMS continuously monitors individual cell voltages, overall pack current, and temperature to ensure safe and stable operation. It provides multi‑layer protection against critical faults including overcharge, deep discharge, overcurrent, short circuits, and temperature extremes, safeguarding both the battery and connected electronics.

Built‑in automatic passive balancing helps equalize the voltage of each cell during charging, thereby enhancing battery performance, efficiency, and lifespan. The 60A continuous current capability makes this BMS suitable for applications requiring moderate to heavy current draw, such as e‑scooters, electric bikes, solar battery banks, UPS systems, and custom lithium battery solutions.

JBD smart BMS models generally support UART communication and often offer optional Bluetooth or CAN connectivity for real‑time monitoring and configuration through apps or software. Users can view key metrics like cell voltages, total voltage, current, temperature, and SOC (State of Charge), as well as tune safety limits and other parameters.

The construction uses high‑quality MOSFETs, durable PCB materials, and low resistance design, ensuring efficient heat distribution and reliable long‑term performance under variable load conditions.
