Why Choose Lithium?
Long-Lasting Performance
LiFePO4 lithium batteries are built for far more life cycles than standard lead-acid batteries, helping you get more long-term use out of your cart.
Better Endurance
Lithium delivers steady, usable power without the same heavy voltage sag many older lead-acid carts experience.
Maintenance Free
No watering, no acid, no corrosion cleanup, and no routine lead-acid maintenance.
Much Lighter
Dropping battery weight can improve cart feel, handling, and efficiency — especially compared to traditional lead-acid battery sets.
8-Year Warranty. Real DIY Confidence.
Patriot Power Source batteries are designed to make lithium upgrades easier for everyday cart owners. Instead of wrestling one oversized 36V or 48V battery into place, our modular 12V battery setup is easier to move, easier to ship, and easier for most DIY customers to install.

Let customers speak for us
Even though the unit wasn't powerful enough for what we needed your customer service was excellent.
I installed 3 of these batteries in a 36v golf cart about a year ago. They work great, so I ordered one to use on a small single tire aircraft tug that uses a 1 horsepower 12 volt DC motor. When I first hooked it up it didn’t work. There is a “button” (which my golf cart batteries don’t have) next to the positive terminal; I wasn’t sure what it was for, but I pushed it anyway and now it works. It must be some sort of reset. I really like the maintenance free aspect of these batteries versus the lead acid variety.
Unbelievably light. they work and charge great so far. Shipping was faster than expected. hope they last
We were on our first day of a week long vacation when we had an issue with our charger. We contacted customer service after hours on a Sunday, and to our surprise the instantly responded. They shipped us a new charger the next morning and got us back up and running!!
Very easy to order, friendly people and the item came in a few days which I was totally surprised, I thought I wouldn't get it that quick. Works beautifully!!!

This kit brought back a lot of life to my old Club Car. It is faster and more fun to drive around. Installation was pretty easy and quick.
PATRIOT POWER 36V CART LITHIUM CONVERSION KIT
Talked to Trey about the differences between single battery vs 4 battery setup, and was impressed with his knowledge and salesmanship. He was extremely helpful in my purchase decision, and I cannot wait until I get my cart back from my service people.
Get product, customer service and support!
I recently replaced my lead acid batteries in my EZ Go RXV golf cart. The conversion was pretty straight forward and simple. I did have a minor issue, which was taken care of by customer service (Trey) in a speedy fashion. I'm very pleased with the results and performance. Highly recommended !

We just purchased our 3rd set of Patriot Power Batteries for our 3rd cart. Installation was a breeze! Cart runs just incredible now! Well worth the money and insanely fast shipping.
Excellent all the way! Trey was very helpful in ordering my batteries. Subsequent communication was great. Batteries arrived on the date promised. The batteries are holding charge. After charging, there is Little or no loss in voltage for 18 hole round. I am glad I swapped Trojan lead acid batteries with Patriot Li ion batteries.
