I have converted my 2017 Yamaha Drive2 PTV golf cart to run on four RELi3ON® InSight lithium 48-volt batteries. I went with four because of the significant elevation changes on both of my home courses. If your course is flatter, and you typically only play one round a day, you could just use two of the RELi3ON batteries.
The process was fairly easy and the results fantastic. Now, even after driving around and playing 36 holes on my very hilly courses, the remaining charge is still in the mid 60% range.
Handling and “zippiness” are superb due to the permanent weight reduction. Another bonus is not ever having to think about checking and adding distilled water to the batteries.
