12v vs 6v

Z71mtr

We got my dad a cart and it needs new batts. The only thing is he is not going to be driving it very far at all and I hate for him to spend the money for 6-6v batts when 3-12v batts will get him where he needs to go. He will not be driving it more than an hour at a time. To his deer stand and around the yard. What are yalls thoughts on this?

I would so no on the 3 - 12 volt batteries, just think about your dad out in the woods with dead batteries and has to walk back because you wanted to save a few hundred dollars for cheaper batteries that don't belong in a cart, a golf cart with 6 - 6volt batteries only has 1 and a half hours of pedal time before they need to be recharged,

How long will 3-12v last because is deer stand is about 400yards from where he parks his truck. All this started from a friend of mine plays 9 holes of golf and he only has 3-12v batts in his and its not even dead when he gets done. I guess I am in the middle on this one because I do agree with you rib.

Battery run time

Actual run Time? The question comes up often enough that I copied this answer from Rabbit, I thought it was a good one....

(It is) not possible to say the actual drive time. When we dealers test batteries, we use a discharge machine that takes the batteries from a full charge down to the shutdown voltage of the cart (for example, on a 36 volt system, the cart is considered in "shut down" at 32.5 volts on the pack under load). The length of time it takes to do this, coupled with the ambient temperature, gives us a rough idea of the life of the battery pack (as well as points out any bad batteries in the pack). As a general rule of thumb, any discharge time above 80 minutes is considered fair, above 90 is considered good, and above 100 is considered very good. A brand new set, properly charged and broken in should discharge at approximately 110 minutes.

The reason I gave all that information is that during "normal" operation, you are not actually running with the pedal down for 5 hours. If you were to start out and run full pedal down without let-up, the batteries should last roughly the same as a "discharge test"

We bought 6-6volt batts today. I didn't want him running it dead in the woods.

That's great, charge them batteries before you use the cart, new batteries are only about 70% charged when you get them home, if you have a TOW/RUN switch, flip it to TOW before you disconnect any cables or wires

Good call
