Power you can Trust.
Most lithium battery manufacturers seal their packs shut—glued tight to hide shortcuts and cheap components. Not Fleet Lithium. We proudly show off the superior quality and craftsmanship inside every battery. From our 300-amp NexGen smart BMS and active cell balancing, to our built-in automatic fire suppression, Fleet Lithium has nothing to hide and everything to prove. See the difference real American innovation makes—because when you invest in Fleet, transparency and performance come standard.
Let customers speak for us
Great Quality and Easy to Install. Highly recommend and will be using more.
Swapped into my Badboy buggy in under an hour. The cheap packs I tried before would cut out during heavy use; this Fleet Lithium pack never throttles. I get about 40-44 miles on flat courses.
I installed this pack in my Textron Prowler EV two months ago what a difference! Other cheap lithium packs would randomly shut down mid-ride, but this one delivers consistent power. I'm regularly seeing 42 miles per charge, though it varies with terrain and load.
Fleet is what they said it was: reliable, strong, and no drama.
I swapped out a RoyPow and couldn’t believe the torque boost. Fleet is on another level.
Instant power, zero maintenance. Way better than anything I’ve used before.”
Absolutely the best built Lithium Battery on the market.
The Huge BMS handles the most extreme terrain, without compromise.
I own a Badboy buggy and cheap lithium packs always failed within months. This bundle's decade-long warranty, plus the protective cell gap, ensure it won't quit on me. I average about 41-46 miles depending on conditions.
My Textron Prowler EV had issues with past packs shutting down. Fleet Lithium support helped me update firmware via the app, and now I hit around 42-45 miles consistently.
I was nervous after cheap packs shut down unexpectedly. Installing this in my Textron Prowler EV, the built-in fire suppressor and NextGen BMS gave peace of mind. Saw over 43 miles in mixed driving.
In my Badboy buggy, heavy hills used to kill my cheap pack. With this bundle I maintain steady power and get 40+ miles before needing a recharge.
Installed in my Badboy buggy, I've gotten a solid 44 miles on a single charge cheap packs I tried would die at 25-30. Smooth operation and zero shutdowns even under load.
Living in Wisconsin, I needed reliable heat. Other cheap packs shut off when temps dipped, but the built-in heating elements on this bundle keep my Badboy buggy running smoothly. I've been hitting around 45 miles per charge, depending on usage.
I installed this 36V battery in my off-grid solar system, and it has been a game-changer. It holds a charge for days, and the extra voltage helps to power more appliances with ease.
Had an issue with my battery gauge - fleet customer service had one shipped out to me
Next day - great customer service !
