Battery

[Merlin]

Thank you David, we have a group 27 flooded battery that is just old.( was original when purchased last fall).

The battery will not hold a charge so it is time to replace. More than likely I will just buy a Duracell Platinum AGM from our local Sams Club.

Do you know if a group 31 battery and box will fit on a stock 2015 14BDS?

Since you have a Sam's membership and a group 27 battery, I don't think you can go wrong with this Duracell group 27 AGM marine battery. It will give you around 50Ah of power (more occasionally if needed), charge fine with your present converter, and fit the tray/box/wiring you already have. It will last a long time and need no maintenance other than making sure the connections stay tight.

I bit the bullet and purchased a 100 AH Battle Born LiFeP04 a couple of years ago. Coupled with 200 watts of solar, by far the best upgrade I could ever make on my trailer.

I just returned from a camping trip where we ran the fridge on DC while driving 2.5 hours, leaving the battery at 60% when we arrived at camp.  A couple hours of low Sun brought the battery back to about 70% before sundown.

Overnight temperatures were in the 20's and we ran the heater all  night. Battery was at 30% the next morning and within one hour after sun reached 30-45 degree angle the battery was back at 100%.   Next night I turned the heat up higher and went from 95% at sundown to 60% the next morning.
