4-12's or 6-8's which way is best

[bill-e-boy]

so I've been reading -
I've got 4 (black recycled trojan) 12 volt batteries in my 48 volt cart, and I've read where some people like the older 6 8 volt set up better.

which set up is better - seems I've only read that you'll get longer runtime from the 8 6volt set up - any other advantages of one setup over the other in my cc iq ds 48 volt cart?

is there a comparison thread that I missed?

thanks
