I have a electric powered boat that runs on 48 volts. I use 4 12 volt golf cart lead acid batteries. I charge the system with a 4 bank 12 volt charger. My question is can then 712 monitor the charge or the batteries if the charger cannot be run through the shunt. If not can i reset the unit to full charge every time I charge the batteries. My goal here is to not discharge the batteries to a destructive state. Thanks in advance Doug
