Other 12V Sources with a 24V-12V converter

So when you go to the golf car place looking for their used battery deals you can pick 8v batts, not just their 12v batts.

The place I went to four years ago had 48v golf cars with 6-8s or 4-12s, and they seemed to be going over to the 8s for whatever reason.

I got two used 12v T-1275s, but you would be able to pick three-8s instead if you could fit them.

Forgot about the 8V batts!

But am putting a lot of attention and care into the existing four GC2s. Would like to get 5 yrs out of them at least. Even down to 25% SOC should get 750 cycles out of the US2200s (dunno about the Duracells).

Was concerned about charging two such dissimilar (age, brand, sp. gr.) 12V banks connected in series. So picked up up a Victron "Battery Balancer" that tries to keep two series 12V banks properly charged. It was not very expensive (and not very powerful). But so far seems to be working as advertised; the two bank's voltages when were mostly quite close (<0.1V diff), although I only monitored it that one time.

Wouldn't work with three 8Vs though.:(

And who knows what battery technology will be available and affordable if I can keep these ones running for 5 years?
