Default Re: Going from (6) 6 volt batteries to (3) 12 volt

Advantages: Unless you can get car batteries for free, no advantage.

Disadvantages:
- Less run time

- They will not tolerate discharging abuse as well as deep cycle

- Therefore you have to monitor their voltage at all times

- Charger designed to charge ~220 A/h batteries so it will cook the 50-60 A/h car batteries unless charging is monitored and shut down when charge is complete for these small batteries!

Having said all that, I AM running car batteries in my cart but I doubled up their capacity by parallel pairing up 2 and I also run twice the voltage ( 72 V)by having 6 of these pairs in series with the appropriate controller which further cuts the amperage abuse in half.

I also run voltage monitors and I do not charge them unattended!!!

It's not for everybody.

I recommend the correct golf cart batteries when it's time for a new set!
