Monitoring your battery bank is easy with the Battery Monitor Kit. 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 Energy InverterCharger and 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.. Item Weight – 3 lbs.
