Bmpro Bc300 + Commlink for Lead Acid and Lithium Batteries
Item as described. Fast shipping even over Chrismas period.
We bought this shunt so we could hook it up to our battery management system. As we installed a diesel heater and an external MPPT solar controller, we needed to make sure our battery management system knew about the external draw on the battery. It worked a treat
