All aux battery related wiring is 2GAGeorge, Can you describe the wiring and fuses that you use for your aux battery setup?
I have one of those same batteries and I am thinking of adding a second one.
What wire gauge from your alternator to your battery bank, fuse sizes for the alternator run, fuse for between batteries, fuse for the inverter?
Thanks!
There's a 80A fuse on the battery hot bus, I had an empty position there. (under the plastic box right off the battery + terminal)
I use a Stinger 80A relay switched with D+ to connect the house and vehicle batteries.
The Stinger 80A relay is to the left.
Then I have a 80A fuse between the relay and the batteries under the passenger seat.
An additional 80A fuse is between the batteries and the inverter
That's my old inverter since replaced.
Cheers
George
