Let customers speak for us
Absolutely Incredible Range. We replaced our 4 year old Trojan batteries this spring with the 210 AH dual battery kit and we are blown away! We use the buggy to secure the perimeter of a 300 acre lot in South Carolina. We typically put about 200 miles per week on this unit. We have been testing this kit for about a month now and we are getting every bit of 80 miles per charge. Its absolutely unbelievable. Thank you Fleet Lithium!
This screen was so easy to install. We installed our fleet lithium battery about 2 years ago, the screen just came out in April, it took 10 minutes to install and everything works perfectly. Thank you Fleet lithium!
After a few months of use I can confidently say this was worth it. No maintenance, great range, and consistent power every time. Huge upgrade from stock.
The range has doubled compared to my old setup. Installation was straightforward and the instructions were clear. I can now play multiple rounds without recharging.
I love the Bluetooth monitoring features. No more voltage sag even on steep hills. It's a night and day difference from lead-acid batteries.
Installation was straightforward and the instructions were clear. No more voltage sag even on steep hills. The battery runs cooler and is much lighter than my old one.
This kit exceeded my expectations. The Ranger runs smoother, quieter, and more efficiently. Would absolutely buy again.

Worth every penny for the performance boost. Customer service was helpful with my questions. No more voltage sag even on steep hills.
Everything fit perfectly without any modifications. The battery charges quickly and holds power for a long time. Installed this kit and my golf cart instantly felt more powerful.
Installed this kit and my golf cart instantly felt more powerful. Installation was straightforward and the instructions were clear. Great quality components and excellent build.
We are beyond impressed with the performance of these batteries. They're noticeably more powerful than pretty much any other brand we've used in our shop. And honestly the best part about them is that we don't have any warranty issues, after I installs are done our customers enjoy the units and we don't have to service them several times to get it right like we do with other brands. We are very happy at our dealership with Fleet Lithium batteries. We've installed hundreds of them, I'm not sure why they're not more reviews on these batteries but I can only assume because not many people come back to this website to review them. We're at lakesidebuggies.com and we've installed more of these than I can possibly even count. Nothing but praises for this company.
