Hi All,
Recently purchased a new RV and am about to add a battery cutoff switch (as there isn't one now). I plan to utilize the cutoff switch to also kill power to either the SmartShunt or BMV 712 so it doesn't draw down the battery over time. So I have two questions here I'm hoping everyone can help:
1. Wiring - my thought is to take the battery negative terminal to the switch, then run the switched 'on' terminal to the Battery Minus connection on the shunt. Of course the Load side would have all other loads etc. My thinking is this will allow the shunt to measure everything when intending to power on the RV without drawing down the batteries. Any drawback to this?
2. (and possibly related to Q1) With the wiring idea above will the BMV 712 and/or SmartShunt retain it's previous settings? Will it essentially 'pick up where it left off' as if in hibernation mode?
I'm thinking I'm OK here - but hoping others who've been down this road before might be able to confirm. Thanks much!
