12v Golf Cart Battery Question

Hi BFL13,

Center tapping with the greatest capacity in the middle is a "second best" solution to equal length cables to a load buss bar. The outer batteries will degrade slightly faster.

Putting one twelve volt jar at each end would be my very last choice. They won't charge or load well at all, so I'm glad you can't do it.

Now that the two old 12s have proven out ok at about 250-260AH the pair, I am going with leaving them in the middle with centre tapping for convenience of wiring mostly.

But now I am worried I have too much battery. ISTR it was 2Oldman who reduced from six batts to four because he could never get six full in the daylight provided even with his large amount of solar.

If I go with six batts and even with shallow discharges, I can see how they would never get fully charged and be living somewhere underwater at neutral buoyancy at 90% or somesuch and sulphating.

In winter at 40F with no solar though, it might be possible to do a three day weekend and get home without doing a recharge until home with so many batts on line.

I am stewing about what to do for the next seven weeks here on "summer" routine. Leaning towards just having the 12s and leaving the 6s to sit fully charged with a shot of solar once in a while to keep them honest.

So, Peanut Gallery, what would be the way to go with this "embarrassment of batteries" I have somehow got myself into?

Thanks.
