Probably an EZGO RXV Elite with a Samsung LION powerpack. It's a more proven technology than Club Car's late and pathetic attempt to match it with an LG LION powerpack.

I have maintained fleets of 60, 65 and 67 carts for 13 years now, both up north and in FL.
I have maintained RXV fleets since that model was introduced in 2008, and we got the first ones off the assembly line. I have had a thread on a forum since 2009 documenting all the problems with it, and that thread became the go-to place for other operators (when, in fact, I started it trying to find someone else who could advise me). We were the Guinea pigs, so I became the ex-spirt.
We have had 2008, 2012 and 2015 fleets, and had to replaced more than 50% of the batteries in the 2008 and 2012s. Slightly better with the 2015s. But, I still had to water 260 batteries once a month, clean terminals, and replace borken cables, etc. Distilled water and a tank and pumping system I designed for the 2015s, which lessened our problems. When our EZ Go tech saw my system, he said, "We need to be selling that."
We've had the 2018 Elite LIONs since last winter, and I have not had to touch them. They make the cart 300+ pounds lighter, both good and bad, run for 54 holes between charges, and recharge in 2 hours.
Next Saturday we have an annual tournament with 240 golfers, 120 at 9:00 and 120 at 2:00. For that tournament, the first carts come in, we restock the carts, tees and pencils, put the second group's bag on them, and off they go, almost as fast as I just posted that. You can imagine what happened every year toward the end of the day, when we had to run rental gas carts out to replace the ones that died.
Not this year!!!!
I was in Florida when we got our new carts, and I asked the GM/PGA Pro when they would be arriving, and he said we already had them. Then he said, "What will you do now?" We had debated back and forth for over a year, and he went ahead with the bigger expense because the dealer sweetened the deal and made the monthly payment about the same. When they can warrant the cart for a year more, they can spread the lease out, and lower the monthly. & throw in two new beverage carts!
