Magnum ME BMK Battery Monitoring Kit with Shunt

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-ARC or ME-RC remotes. With accurate SOC readings, you can avoid unnecessary battery recharging, saving on fuel and long-term maintenance costs.

If you already have a Magnum Inverter/Charger and Remote (ME-ARC or ME-RC) (requires remote rev 2.0 or higher), 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.
