Pair it right
Make sure this pack matches your motor
Trolling motors pull about one amp per pound of thrust. Enter your motor, hours and throttle to confirm this capacity covers your day on the water.
Size your marine pack
—
Estimate based on ~1A per lb of thrust at 12V and 80% usable depth of discharge. Message us with your rig for an exact recommendation.
100% usable capacity
A 100Ah lead-acid bank gives you 50Ah before it sags. A Fleet Lithium 105Ah pack delivers the full rating, every trip.
Half the weight
Drop 60+ lbs off the transom versus flooded lead-acid and get it back in hull speed and range.
Flat voltage all day
Lithium holds voltage to the end of the charge, so your motor pulls the same thrust on the last hour as the first.
5,000+ cycles, 10-year warranty
Sealed, maintenance-free and IP-rated for the marine environment. No watering, no acid, no off-season top-ups.

Let customers speak for us
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.
The parts for the EZGO RXV 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 12V voltage reducer provided a clear path for running standard accessories from the higher-voltage battery system. The result has been reliable and easy to service.
