BMPRO BatteryPlus35-II-HA Battery Management System - Lithium Compatible

The BMPRO BatteryPlus35-II-HA Battery Management System is designed for caravan use, managing your house battery and 12V appliances. It integrates a power supply, distribution board, smart charger, solar regulator, and battery protection features into one unit.

This system supports lithium (LiFePO4) and lead acid batteries. It includes a 35A output for 12V loads, a 30A multistage 240V charger, and an MPPT 30A solar regulator for solar power integration. The unit connects via CAN bus for monitoring with Trek battery monitors or Odyssey screens using OdysseyLink.

Prewired with a permanent mains power cable and plug for 240V, it also includes a 40A uncontrolled battery output for devices that require continuous power without isolation.
