Batteries for 38EL

Have a 38EL on order and trying to understand 12v vs. 6V, which is a better approach. 38EL has residential refrigerator and 2 CA units.

Recommendations please.

What about cost and battery life? Anything need to modified for 6V operation?

No change because you wire up two of the 6v together to make them 12v (thatís called ďin seriesĒ). Then you wire up the 2 pairs of batteries in parallel to give you combined sum of amp hours.

See if this article helps your understanding:

Personally, I opted for the high buy-in cost of lithium drop-in batteries from Battle Born and love them. You get more usable amp hours, faster charging, they handle high loads, and are lighter weight than lead-based batteries.

They do all of that but they are not cheap. Care to tell what you paid

We are upgrading our batteries and inverter set up in our 38 FB2. Changing out the 4 Deka 6v GC batteries for 4 ea Battle Born GC2 12v 100amp ones. They are $1049 ea, they had them for $900 ea on Cyber Monday.

Why do you want to change out the batteries?

Do you Boondock if not no need to change out the battery!

Why? At least with my Cedar Creek the inverter only supports the residential refrigerator and nothing else. My 12 volt Napa battery is enough to support the inverter draw down load for one day (over 12 hours). It might be longer but I plug into shore power every night that I am using the trailer. This will recharge the battery and provide a fully charge battery the next morning for travel.

If you are going to Boondock then yes, go the extra mile and install solar power also for those 4-6V batteries to recharge them.

Just my $0.02

Unless your 38EL is different from mine, you don't have room for four 6V batteries. I think they changed the trays in 17 and the new ones will only hold one battery on each tray. I used 12V "31" which fits snugly in the tray. You can pay what you want for the batteries to increase the load life.

I had two 12v AGM batteries put in our new Champagne and a 50amp Boondocker converter. Itís a four stage converter, spikes and if not being used drops down to a trickle charge. Iíve had this combo in our trailers and it works well
