3 12V vs 6 6V

[DRAGMACEDAD]

Am in the process of selling my Hyundai mid 90's and the first question is "how are the batteries?" one guy asked if he could use 3 12v instead of the 6 6V"S... pros cons?

Thanks..

3/12v = 36v?
Or can I use 3 12v batteries in my 36v golf cart?
You can use 3/12v batteries in series to create a 36v power supply. However this supply will be lacking in amperage capacity and deep cycle ability. The result will be poor run time and shortened battery lifetime.
The batteries used in your cart should be golf cart specific batteries.
Golf cart batteries are designed to hold a large amount of amperage and to be discharged relatively low over a long period of time.
Automotive batteries do not store as much amperage and are designed for shallow discharge and immediate recharge. Like starting a car and having the alternator immediately begin recharging.
Battery construction differs and plate thickness and count per cell varies with regard to discharge characteristics and designed usage. The thinner plates of automotive or marine batteries give up their amperage much quicker than Golf cart batteries.
You can connect 3 automotive 12v batteries in series and get 36v. You will not have the same amperage reserve or operational characteristics needed to make the batteries perform well or last satisfactorily in a golf cart.
But, it will work for testing or short run usage...
I hope this helps ...

I agree with the above, I have been running a set of 3 walmart marine deep cycle batteries in my 93-94 marathon txt, i have a new alltrax controller. I have had the cart for a little over a year. i keep it in my attached garage. i charge it after every use usually for at least 6 hrs maybe 8 hrs if it was really low. I have had ok performance. I cannot run long runs over 2 miles, but it will run around my neighborhood for a day. my wife used it to cruise the neighborhood garage sale it does fine for short trips etc.

scottyb is right on, but for me I bought a crappy cart for $300 put $275 of walmart batteries in it and it run well enough for me to get the controller wet. so i put the new controller in and covered the battery compartment to keep the controler dry its meeting my needs. But I definately suffer from not having the range i want to have. I have been looking at golf cart batteries but it is hard to put down that much money when what i have pretty much works. But I am tired of getting pulled back to the house by my neighbors atvs when we are 3 miles down the trail away from the house.

There are large deep cycle 12v batteries available that may work, but they are so heavy and expensive that its not worth the change. Done some boat stereo using both multiple 6v and multiple huge 12v stand alone storage.

Stick with 6 or 8 :)
