Product description

The HBJ 17S-24S 40A Smart BMS is a high-voltage battery management system for lithium-ion and LiFePO₄ packs from 17 to 24 cells in series, covering 60V and 72V systems, housed in a robust metal enclosure. It is the higher-power 72V option. 40A continuous discharge - about 3,000W on a 20S Li-ion pack - suits 72V electric motorcycles, high-power scooters, electric rickshaws and light EVs running controllers up to 40A, where a 30A board would be the limiting factor. The metal enclosure protects the electronics from knocks, dust and vibration, which matters on vehicles that see daily road use. The board supports 20S Li-ion (74V nominal) and 24S LiFePO₄ (76.8V) - the two standard 72V configurations - as well as 17S Li-ion for 60V packs, with chemistry and cell count set in the app. The Bluetooth app shows each cell's voltage, pack voltage, current and protection status live, so a weak cell in a long 20S or 24S string can be found before it strands the vehicle. The common-port design uses one pair of high-current terminals for both charging and discharging, keeping vehicle wiring simple where the charger and controller share a connection. Protection covers overcharge, over-discharge, overcurrent and short circuit, with cell-level monitoring. For lighter 72V e-bikes with controllers up to 30A, the HBJ 17S-24S 30A smart BMS is the more economical choice.
