I want to use a Orion-TR Smart 12/12V-30A Isolated Charger on a new install in a motorhome.
The chassis and house batteries both use the chassis frame as ground. I want to simply tie the two negative sides of the Isolated charger together and use a single cable to ground. I can't see the need for two separate cables to ground. Am I missing something?
Or is this just a bad idea and I should get a non-isolated charger?
Thanks!
@markgmack I have an isolated Orion Smart in my van for alternator charging, which I ended up installing a common chassis ground when I added monitoring capabilities of my starter battery using the Smartshunt and the Trickle Charge feature if the Multiplus. It works well.
