Install went quick and easy.
The kit included everything I needed.
And my cart has more power and holds a charge for days instead of hours
This is a very high quality battery easy to install, so happy to be rid of the nasty corrosive lead cell batteries. Hopefully I’ll get many years of service out this battery and I’m sure I will, just the getting rid of the lead cell maintenance is a huge win. The cost of corroded cables, hold down brackets and adding water was a pain in the butt.
Nice and easy install, they work great, much longer range and way better power. Best of all, NO MAINTENANCE
Tried cheaper lithium setups first and they couldn’t handle the amp draw. This one has been solid with no issues.
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.
I should have just bought this first instead of wasting money on others.
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.
Real world use, not just cruising. This battery actually performs.
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.
