Description  

A smart battery management system designed for LiFePO₄, Li-ion, and LTO packs. Supports 3–8 cells, with 200A continuous current and 1A active balancing for longer battery life. Features Bluetooth monitoring, RS485/CAN support, and full protection against overcharge, over discharge, overcurrent, and temperature. Compact, efficient, and ideal for solar, EV, and energy storage applications.
Key Features & Benefits

  • Supports 3S to 8S configurations (for Li-ion); 4S to 8S for LiFePO₄; 6S–8S for LTO. 

  • Continuous Current: 200 A, with peak discharge up to ~350 A (2 min max)

  • Active Balancing, 1 A rate (energy transfer type) for superior cell equalization, reduced capacity drift, and extended battery life 

  • High accuracy voltage detection: 0–5 V single cell range, typical error < 5 mV, full range error < 10 mV 

  • Multi-mode protection suite: overcharge, overdischarge, overcurrent (adjustable between 10–200 A), short circuit, overtemperature, etc.

  • Thermal & environmental resilience: operating −40 °C to +85 °C, storage −40 °C to +95 °C

  • Low power consumption: < 5 mA (without communication), standby < 2 mA

  • Smart connectivity & monitoring: built-in Bluetooth (Android/iOS app) + support for RS485 / CAN / heating / optional LCD / GPS interfaces

  • Compact & robust form factor: ~153 × 136 × 18 mm footprint (thickness ~17–18 mm)

  • Common port wiring (shared negative) for ease of integration
