If they fit, 8*6V best value.

Duracell (Deka) flooded GC from Sam's Club or Batteries+ are very good value. Trojan T-105 a little better if close in price, RE variant much better but pricey. U.S. Battery, Crown, Superior also very good.

12V rarely as robust or long-lived.

Going for a used EV pack would be lighter but lots more expensive installation, IMO much riskier.

Very few 12V are available as robust as lower voltages, as well designed for deep cycling.

Yes new lead is best value where weight is not a problem.

I stand by the Deka / Duracell recommendation above, as well as the pricier ones, all built for that specific purpose and a no-brainer drop in.

Go talk to the cart guy at any large golf course near you.

12V: T-1275 150 Ah, 85 lb (39 kg), so a set of four is 150 Ah @ 48 V in 340 lb (156 kg)

Problem isn't just weight.

The vendors design most 12V to not last nearly as long as the 6V units, often **half** the rated cycles for a given cycling depth.

And they're more expensive per AH.

For price and performance, stick to 6v.

Yes sorry you're completely right, about that model, sorry.

There are others, exceptions that prove the rule.

And whatever the cause of price differences, the GC 6v I spec'd above can't be beat for value.
