we have a 2010 Tomberlin, for 6 years now. Generally love it. Out last set of batts from Battery Boys - Trojan are almost 4 yrs old. Starting to lose range. We plan to keep this cart...forever... as it's perfect for us.

That said we will prob want to change batts by early next year. I would not simply replace with the usual lead acid Trojans. Would definitely go with Lithium, as an investment with longer life and better $$$ payback if we ever sell...or croak. I plan to call battery Boys and Luxus (Tomberlin/Leesburg dealer were we get service) to check re Lithium. I went onto BB site, and surprised...zip re lithium.

The NMC chemistry is safer and more durable. You need to charge Lithium batteries slowly to avoid dendrite formation and possible short...Keep under 25A and it will be fine. The latest lithium battery tech (safe and durable) is available now in the new Hyundia Ioniq 5 with its 350kw max DC charge. That is the only EV car I would recommend. I still wouldn't shove 350kw into it.

I charge my lithium pack to 90% ... and at 22A max. The slower you charge any battery, the longer it will last.

I’m not here to argue about something that me, you or anybody else know a lot about. All I know is the price on these new type of cars are going to be more expensive, when batteries need replaced it’ll cost several thousands of dollars. Like you said Tesla are WORKING on a million mile battery, more like batterIES, these cars will take more than one battery. I noticed I didn’t see a price on these batteries. I know a little bit about cars since I’m retired from an auto engine plant after 38 yrs. I hope you’re right but to many people think these electric cars going to be built like HASBRO builds toy cars. Time will tell & I hope you’re right!

An approximate range for a cart with an AC motor is 100w per mile...Or 2ah per mile with a 48V system.
The EZGO RXV does a little better than that.

BTW - Elon Musk is a con artist. It should be obvious by now.
He is an embarrassment to people with a physics and chemistry background.
...And Tesla is just a toy.

After about 300,000 miles your range will have dropped from 250 miles to about 200 miles.
It would be about time to replace the batteries at that point.
Just keep DC Fast charging to a minimum.
11kw house charging is fine...0-250 Miles in about 7 hours at that charge rate.
120V charging will charge at about 3 miles per hour.
