Batteries and Inverter Installed

Hey guys I know I asked a bunch of question on Lithium, but in the end I decided to go with (4) 6v batteries from Costco. I appreciate all the feedback on the forum.

So the trailer has a steel-floor compartment between the landing jacks and forward of the basement that the perfect spot. The camper was built with 1-12v batter in the forward curbside compartment with the jack hydraulics.

I stole the idea from another poster that commented on my other thread and found a plastic storage tub at the home center that would fit 4-6v batteries.



I used #4 wire between everything.

I added a vent hose and routed it to the original vent in the front of the trailer. I also added an intake at the bottom of the box with a hose that draws fresh air from below the floor.



I installed the Xantrax 600W inverter and 15a trandfer switch on the wall right above the batteries:



Inside I added the Xantrax remote, battery gauge and Progressive Charge Wizard to the switch panel by the door. The trailer already had a PD 9260 installed, so all I had to do was add the remote pendant.

  • Forgot to mention that I used 2"angle iron and welded a frame around the battery box with supports across under the batteries.
  • Looks great. Those Costco 6ers have served well for many RVs including 15 years in mine (2 sets).
  • Actually I recreated this chart from an old .jpg and that 12.6 is supposed to read "12.6+"
  • Nice job! Beware of that battery SOC table showing 12.6 is full. Your 6s will probably be more like 12.75 when full (resting)
  • Very clean and neat. Using #4 wire should mean close to no loss. “FRESH” dates on batteries…2/22!
