Jiabaida Smart BMS 7–20S Li-Ion – 150A temperature sensor JBD
Jiabaida Smart BMS 7–20S Li-Ion 150A with Temperature Sensor – JBD
The Jiabaida Smart BMS (JBD) 7–20S 150A is an advanced battery management system designed for Li-Ion battery packs. It ensures full cell protection, stable battery operation, and real-time monitoring of pack parameters.
The BMS supports battery packs from 7 to 20 cells in series (7S–20S) and is an ideal solution for batteries used in electric bikes, scooters, energy storage systems, electric vehicles, and DIY projects.
Thanks to the Smart BMS functionality, it is possible to read battery parameters via an app (Bluetooth / UART – depending on the communication module version).


Key Features
✔ supports 7S–20S Li-Ion battery packs
✔ maximum discharge current: 150A
✔ active temperature sensor protecting the battery pack
✔ intelligent battery management (Smart BMS – JBD)
✔ cell balancing for longer battery lifespan
✔ overcharge and over-discharge protection
✔ short-circuit and overcurrent protection
✔ monitoring of each cell’s voltage
Protection Functions
The BMS protects the battery pack against:
- cell overcharging
- excessive discharge
- overcurrent
- short circuit
- overheating
- uneven voltage between cells
This significantly increases both the safety and lifespan of the battery.
Smart BMS Application
The QR code located on the BMS leads directly to the Smart BMS app, which allows real-time monitoring of battery parameters. Using the app, you can check, among other things, the voltage of individual cells, temperature, state of charge, and other diagnostic data of the battery pack.
