Let customers speak for us
Cannot thank these guys enough. Our Hunting buggy is a whole new animal of its own! The team did a great job answering questions, shipping took 3 days and i was even able to reach the support team at 4pm on a Saturday during install. Cannot thank them enough! Don't think twice, Fleet is the way to go for your lithium job.
Was a slight hick up with the darn computer bot. Once we got thru that the service and help with my change over was top notch.
Mt Ranger performance is awesome with the Fleet battery
GREAT SERVICE
Awesome kit. We Live in a very cold climate, our ranger gets a ton of use year round and especially during the winter so the cold weather performance was a must for us. We've had the kit installed for about a year now and it's been perfect. Customer service has been super helpful the one or two times we had questions and we've got a couple of neighbors who run the kits as well and they say the same thing. Kevin and his crew are really top notch!
The 12V voltage reducer corrected the unstable behavior that had affected the lights and other accessories. The output has remained steady through regular use.
The 51V replacement charger is easy to keep available as a backup and works without unnecessary controls. The battery reaches a complete charge consistently during normal use.
The Polaris Ranger EV bundle lined up well with the intended mounting area and the connections were easy to identify. Once installed, the vehicle felt smoother and more consistent through normal use.
The 51V replacement charger connected as expected and has charged the compatible battery consistently. The status indicators are easy to follow, and the unit feels solid in regular use.
Easy installation and great technical support.
After installing the Club Car 48V kit, throttle response felt more immediate and the vehicle no longer felt sluggish late in the charge. The cleaner battery compartment is another welcome improvement.
Cabels look great. Will be installing them by the end of the week. Frank
The BlueMax 200Ah marine battery has provided steady power for onboard electronics and normal time on the water. It is easier to handle than the older battery and has required very little attention between trips.
The parts for the EZGO TXT kit were organized clearly and the installation sequence made sense. The finished setup looks tidy and removes the routine upkeep of the old battery bank.
The 76V replacement charger replaced the previous unit without requiring a complicated setup. Charging has been predictable, and the connector fits securely.
The plug on the 51V replacement charger seats firmly and the unit maintains a normal charging cycle. The battery has been ready for use each time charging is complete.
