The (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. However, this shunt is required to be installed in the battery system for the Battery Monitor to work. .
