Magnum ME-BMK Battery Monitor State Of Charge With Shunt

Magnum Energy


Monitoring your battery bank is easy with the Battery Monitor Kit (ME-BMK)* from Magnum Energy. Acting as a ?fuel gauge? for your batteries, the ME-BMK monitors their state of charge (SOC) and then provides this information in an easy-to-understand display via the ME-RC remote. With accurate SOC readings, you can avoid unneccessary battery recharging, saving on fuel and long-term maintenance costs.

If you already have a Magnum Inverter/Charger and Magnum Remote*, the ME-BMK is an easy retrofit. Simply install the kit according to the installation manual and begin monitoring your battery bank via the ?Meter? button on your ME-RC.
