Using Ryobi 18v Batteries in 36v Golf Cart

stevenjmorales · 01-11-2022, 06:07 PM

Has anyone tried powertool or lawnmower batteries as replacements for golf cart batteries?

A golf cart lithium battery I saw was 10ah.

There are some powertool batteries that come close to that or a couple run in parallel.

Example: using 4x 18v/6ah batteries configured for 36v/12ah.

I could see it only running for like an hour, but faster as it would be much less weight.

Any thoughts?

You are way off. Minimum AH for a cart is 60AH with Lithium at 48V. You won't be able to pull enough current from any reasonable setup with power tool batteries. (300 amps peak minimum)

Agreed! It would be the equivalent to running an tractor trailer on a weed eater gas tank!

That's the example I give anytime someone comes in my shop with 3 12 volt cranking batteries in a golf cart and can't figure out why it won't run more than 10 minutes!
