Took the GX and camper to Broken Bow.
I removed the 3rd row seats, and for now just have the bare vehicle floor surface covered with the Weathertech cargo mat. I’ve ordered the Goose Gear base plate but don’t have it yet.
There are 2 30A circuits - one for each of the 3rd row seat motors - they’re always hot. I used those circuits in parallel to feed an Anderson SB50 connector. They are only 12 or 14 AWG, but with them in parallel, each wire only has to carry a max of 15A to feed my 30A DCDC charger, so well within the current carrying capacity.
My “battery box” has:
- DCDC dual input charger (input for solar / MPPT, and an input for alternator)
- 100Ah lithium battery - space provisioned for a 2nd one, which should be here today and I’ll install it
- both batteries fused and connected to a distribution buss bar
- two SB50 connector “outputs” connected to the buss bar
- a fused distribution block for connecting small loads (USB, 12V, hella, etc), which I will add and make accessible from the box
- all wiring is either 4 or 6 AWG
I plug the SB50 connector from the seat motor power into the “Alternator” input to the 30A DCDC charger, and the vehicle charges the battery at about 26 amps when engine is running. The DCDC charger is smart enough to disconnect when the car is shut off and voltage drops to the 12V range so it won’t drain my start battery.
When my camper batteries need to be recharged, I connect one of the SB50 outputs to my trailer charge controller, and it charges my trailer batteries at about 28 amps.
Very happy with the setup - 400Ah of lithium battery capacity, and 500 watts of solar if sun conditions are right.
Broken Bow is a beautiful area - explored a few FS roads with the family and will definitely be going back a few times.
