BMS NMC 17S 40A JBD (ZP20S007) (55a5)

The JBD NMC 17S 40A BMS (model ZP20S007 / 55A5) is a smart and efficient battery management system designed for 63V lithium-ion (NMC) battery packs. It supports 17 series (17S) configurations, making it suitable for high-voltage applications such as electric vehicles, solar storage systems, and industrial lithium battery packs.

This BMS is equipped with advanced battery monitoring and protection technology, ensuring safe and stable operation. It continuously monitors individual cell voltages, pack current, and temperature, protecting the battery from overcharge, over-discharge, overcurrent, short circuits, and overheating.

The system features automatic passive balancing, which equalizes voltage differences between cells during charging. This helps improve battery efficiency, prevents imbalance, and extends the overall lifespan of the battery pack.

With a 40A continuous current rating, this BMS is ideal for medium-load applications like electric scooters, e-bikes, solar energy storage, UPS systems, and DIY lithium battery projects.

JBD smart BMS models support UART communication, RS485, and optional Bluetooth connectivity, allowing users to monitor real-time battery parameters such as voltage, current, temperature, and SOC (State of Charge) via mobile apps or PC software. Parameters can also be configured for customized performance.

Built using high-quality MOSFETs, low internal resistance circuitry, and durable PCB materials, the BMS ensures reliable operation and efficient heat dissipation.
