BMPRO BC300 + Commlink for Lead Acid and Lithium Batteries

Enhance your battery management system with the BMPRO BC300 External Shunt and Commlink. This solution is designed for accurate capacity monitoring, especially in lithium battery systems fitted with Diesel Heaters, which must be direct-wired to the battery rather than through the battery manager.

Monitors All Connections Direct to Battery

The BC300 External Shunt and Commlink integrates with your BatteryPlus35 and J35 battery management systems to support high current loads and external charge sources connected directly to the battery. It also offers temperature monitoring for added battery protection.
