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).

📦 Physical Details

• Size: about 120–140 mm × 65–70 mm × 14 mm
• Weight: about 140 g
• Port type: Common port (same terminals for charge & discharge)

🛠 Typical Applications

• Electric scooters / e-rickshaws
• Solar energy storage batteries
• UPS / inverter backup systems
• DIY LiFePO4 battery packs (~60 V)
