Costco vs Sams Club 6V Golf Cart Batteries

I finally ended up going back to the original set up...Two-12v batteries I bought from ,,,Yes, Costco. I got their group 24 series (85 amps each x 2 = 170 total amps) RV/Marine Deep Cycle batteries.
I would have liked to have bought their group 27 size (115 amps each), but they were just too big for my tray.

I have already tried them out on 2 camping trips and I am believer in them again. I was able to watch TV (over an hour) again without that darn inverter warning alarm going off within 10 mins (indicating a low charge) and whenever my water pump turns on now, my lights dont dim or flicker like they did before.

One other thing I dont need to worry about...with the 6 volts, if one of them went bad, I was SOL. With the 12 volts, one can go bad and I am still up and running.

I took care of my past batteries...almost to the point of being anal about them.

All I know, this is my 4th set of batteries since I bought my rig in Dec 2005 (first set of 12 volts were still working when I went to 2-6 volts....second and third sets were 6 volts, now back to 2-12 volts)and that doesnt seem right.

I know others love and swear by their 6 volts and that is great...but not me, I am staying with 12 volts from now on.

12v batteries are the best choice for many for the reason you state.

In our case the starting battery and house batteries are mounted right below the radiator of our P30 chassis. By just moving cables I can move to one of the house batteries and use it as our starting batteries. The last two PO's only had one house battery but the rack was built to how two plus the starting batteries. When our engine alternator was out for a couple months before I got it into the shop for other things I kept one house battery fully charged but not connected as a back up starting battery should we run down the starting or the one house battery. I hate to be out without a working starting battery. :)

We can use the DC-27 size and that gives us 230 AH. At the office on the UPS I find that four DC-24's live longer than the DC-27's in that 48v set up for some reason.
