The ME-BMK-NS (Battery Monitor Kit - No Shunt)* from Magnum Energy gives you a "fuel gauge" type of meter for your battery bank. It monitors the battery bank and reports the percentage state of charge, real time amps, voltage, amp-hours in/out, and the minimum/maximum DC volts. The Battery Monitor Kit includes the sense module, sense and communication cables. This ME-BMK-NS is identical to the ME-BMK except it does not include the 500A/mV shunt. However, this shunt is required to be installed in the battery system for the Battery Monitor to work.
