Battery monitors can display many different values on the screen including voltage, amp hours consumed, amperage, state of charge and more.


The "V" screen, as shown here, measures voltage for the house bank. This voltage reading is showing the battery being float charged.


This particular model, the Victron BMV-602S, can monitor the voltage of two banks as can the Xantrex Link-Pro & Link-Lite models from Xantrex.
