Description
BMS LFP 19S 40A JBD (ZP20S007) (3112q)
BMS LFP 19S 40A JBD (ZP20S007) is a Battery Management System made by Jiabaida (JBD) for LiFePO4 battery packs. It manages and protects a 19-series (19S) lithium iron phosphate battery, typically used in ~60 V systems.
⚡ Protection Features
This BMS protects the battery from common faults:
- Over-charge protection (~3.75 V per cell)
- Over-discharge protection (~2.2 V per cell)
- Over-current protection
- Short-circuit protection
- Temperature monitoring (NTC sensors)
- Passive cell balancing to equalize cell voltage
🔌 Communication / Monitoring
Some versions support:
- UART
- RS485
- Bluetooth module (optional)
This allows monitoring on PC or mobile apps (cell voltage, temperature, faults, charge/discharge data).
