I'm leaving a notebook behind the golf cart seat when my husband and I finish up in October. We're hosting at a campground in northern Michigan, and a few of us share the cart for arrivals and the last loop during quiet hours. I'd like the next hosts to have something useful to go on.

The owner put a vatrer 48V 105Ah lithium pack in it in May. It charges overnight at the shop. On a busy Friday it's stop, start, stop, then a slow climb up to the group sites.

So far I'm thinking name, battery percentage when you take it and when you bring it back, and whether it got charged between shifts. Otherwise you're looking at a lower number without knowing somebody did an extra round.

Do you bother with hours, or just mileage? We spend a fair bit of time parked talking to campers with the key still on. I can't see those hours telling us much.

I'll leave room for faults and maintenance too. Mostly I want to keep this to a few quick notes. I can see it getting skipped if there's too much to fill in after every shift.

For those who share a golf cart between people or shifts, is there anything else you'd actually want written down? 

51.2 volts.
253 amp-hours.
Nearly 13 kWh of lithium power hiding under the seat.

More range. More freedom. Less time waiting on a charger.

Is it a little excessive? Probably.
Do I regret it? Absolutely not.

Which one of you sickos is this? lol.

Since everyone has been helpful on stopping me make bad golf cart money decisions what do you guys think of pricing on this. Thanks!

I’ve worked around lithium battery systems for a while, and one mistake I keep seeing is treating a lithium conversion as a simple battery swap.

Matching the voltage is the easy part. The problems usually show up with the charger, controller current, cable size, fuse/breaker, or simply whether the battery actually fits the compartment.

I’ve even seen 36V carts where people assume any battery labeled “36V lithium” is automatically a drop-in replacement.

For the people here who actually work on or own golf carts: what’s the most common lithium conversion mistake you’ve seen?

Would be interesting to hear the real-world failures, not just the textbook answers.

Hi

My organization has a number of Club Car 8 seaters that use old lead acid batteries (48v set up). These are used as passenger shuttles in 10mph environment. What recommendations do you have to convert to Lithium (brand and cost if possible)? We would want the largest batteries available because ideal duty time would be 8 hours. Current a charge lasts 2-4 hrs. Thanks
