Description
The JBD (Jiabaida) 10–17S 40A Semi-Smart BMS is a programmable protection board for lithium battery packs from 10 to 17 cells in series. One board covers 36V, 48V, 52V and 60V packs, and can be set for NMC/Li-Ion or LiFePO4 chemistry. It protects against overcharge, over-discharge, overcurrent, short circuit and over-temperature, balances cells during charging, and connects to an app or PC via its UART port for monitoring and parameter setup.
Key Features
- 10S–17S in One Board – Covers 36V to 60V packs; reduces SKU count for pack builders
- NMC & LiFePO4 Compatible – Chemistry and protection thresholds set via software
- 40A Continuous Current – Rated 40A continuous charge and discharge
- Common Port Design – Charge and discharge through the same terminals
- UART Communication – Connect a JBD Bluetooth module or PC adapter for live monitoring
- App Monitoring – View cell voltages, current, temperature and SOC via the Xiaoxiang app (with BT module)
- Adjustable Parameters – Set OV/UV, current limits and temperature cut-offs to suit your pack
- Cell Balancing – Equalises cell voltages during charging
- Complete Protection – Overcharge, over-discharge, overcurrent, short circuit and over-temperature
