Batteries and Inverter Installed

[BurbMan]

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.

Would this be a rreason to use AGM batteries?
Checking once a week seems like a lot? Would AGM's require minimal water checks?

There is no way to check water in an AGM.

With that in mind what is the down side of using AGM'S Price?

You need to check the water in the batteries at least once a week. Hot weather and multiple discharge/charge cycle will cause evaporation. Depending on how much you use your RV, you probably need to clean the batteries every 3 - 6 months.

I have just two words to say about that install: Looks Good.

BurbMan,

So nice to see the balanced wiring! Well Done!

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!
