12v Optima


New Member
I have a 36v 1990 EZGO that has recently died. The 6 6v batteries were connected in series to get the 36v. I was wondering if it's possible to replace those 6v batteries with three of those 12v deep cycle Optima batteries in series. As long as I get the 36v it should be fine, right? I understand that with 12v you don't have as many amp hours, but the Optimas boast insanely long amp hours anyway, so I don't think it's an issue. Just wondering about the main difference between 6v and 12v. Thanks a lot.


Hi and welcome to the forum. The three 12 volts will work but will reduce run time quite a bit. The more lead the better the run time.
