24V Golf Cart

Can you have a 24V golf cart from 3 8V Battery's?

if Controller can Handle it?


Will it Work?

Yes, slow and unable to climb a hill or go very far but it will work Do you have any 24v chargers. Floor scrubbers used them. My friend used 2 on his 48v cart for about a years time.

A 12V Car Charger should work. It worked for my Other 36v.



What do you Think?

I think you are barking up the wrong tree.

Reducing the voltage to a 36v motor will reduce the torque and speed of the motor. Unless the load is reduced by the same amount, the performance will be way down.

Here's an Idea. What If I install all (6) 8Volt Battery's to make 48V, Then buy a Voltage reducer to reduce 48V to 36V and then charge it with the 48V Golf Cart Charger?

Do you know of any voltage reducers that will do This?

PS, I think I will be known as the Most Annoying person on the BGW Fourm.

LOL, I'm just Desperate

1. I believe I'd be able to walk faster and I use a cane.
2. Without knowing the Amp-hour rating of the 8V batteries, it is impossible to estimate, but if the are similar to a T-860, my guess is no more than half an hour, or about a mile at the predicted 2 MPH.

Suggest you put it together, try it and tell us what the results are.

A voltage reducer that will pass 275A to 300A peak and around 75A-100A continuous is going to cost more than a 48V controller and Solenoid.

"I will" is future tense, "I am" is present tense.

They are Trogan T-860

I shouldn't even Bother. LOL

That is only a 150AH battery and running at reduced voltage is going to increase current flow, just like running at a higher voltage decreases current flow.

If kicked it around a bit, but I honestly don't have the slightest idea what the run-time would be because I have no idea how much current a 36V system will draw when ran at 24V.

Even if you could cut one in half and use four and a half 8V batteries for a 36V pack, the run-time would be less than 2/3 of a T-105 (225AH) because the current draw would be a higher percentage of the battery AH rating and the higher the current draw relative to the AH rating, the fewer Amp-Hours can be obtain from the battery (Peukert's law).

If you had 6 of them, you could connect them in series-parallel for a 300AH 24V pack and more than double the run-time on a 150AH 24V pack, but it would still be running at 2/3 normal voltage, so the performance would be dismal.

Personally, I like to find some 300-400AH 2V cells and stuff 18 of them under the seat of my cart, but I'm probably going to have to settle for about 250AH in groups of three.
