After many hours of reading and researching, I have finally decided to post my question.
2009 v10 Cutaway Chassis
Supreme Box
Factory added 2nd frame rail battery
It appears I have the equipped 2nd battery isolator in the engine bay- 2nd Battery in box under passenger side of frame rail
I am wanting to add a bank of batteries ( house batteries ) AGM. Can I tie into the underframe rail 2nd battery directly? Would I need to add a second ACR or some kind of additional switch/relay for the house batteries to charge and disconnect when the vehicle is off?
Do I need to run an ACR standalone of the "factory ACR"? It would be nice to not have to make a run all the way into the engine bay.
Equally, if I tie directly into the frame battery will it matter if I am running AGM vs the I assume lead factory batteries
