      Tired of spending your spring prepping your golf cart for the summer by pouring distilled water into dirty, corroded, 90 pound batteries.....only to ride your cart 3 miles before it starts slowing down?  Better get home and put it on charge!  Not to mention replacing batteries every few years just to ensure your cart's in decent working order!  We've all had that feeling while dealing with the old technology of SLA golf cart batteries.  If you're on this page, you've made the right decision.  LOOK NO FURTHER than Patriot Power Source's advanced LiFePO4 Lithium technology to completely change your golf cart forever.

      SAVE $$$ - While LiFePO4 Lithium batteries cost more than traditional SLA batteries, Patriot Power Source offers you the absolute MOST affordable conversion kit on the market today without sacrificing an ounce of performance.  In addition, considering LiFePO4 batteries last up to 10X longer than regular golf cart batteries, this kit should last you just as long as 3-5 sets of old batteries!

      FREEDOM TO GO FURTHER - NEVER worry about running out of charge again after converting your cart to run a Patriot Power LiFePO4 Lithium Battery Set.  Using our vigorously tested batteries and setup, charging your golf cart after every ride will become a thing of the past.  Unlike traditional SLA batteries, which require charging when they reach 50%, our advanced LiFePO4 Lithium batteries give you full performance down to the very last drop, from 100% to 0%

      SMART CART - Our advanced LiFePO4 batteries contain an onboard intelligent Battery Management System (BMS) to ensure your investment is always protected.  BMS monitors:

      • overcharge detection
      • over discharge detection
      • over current detection
      • short detection
      • temperature monitoring
      • battery balancing

      WIRED FOR SUCCESS - Unlike most competitors, our batteries are specifically engineered to run a series wiring setup, just like a standard cart, to maximize distance.  

      UNLOCK PATRIOT POWER - Our batteries weigh 70% less than a traditional SLA battery removing 300 or more pounds off of your cart.  See your speed, acceleration, and torque all increase by 25% when you convert.

      EASY DIY INSTALL - If you can turn a wrench a few times, you can install your new batteries and convert your cart to a LiFePO4 Lithium super cart.  Seriously, drop in 4 batteries, hook the wires up like they were with your old batteries and take off.  It's that simple.  We'll send you everything you need, and we're always here for ANY questions or help with installing or troubleshooting you may encounter.

      Conversion of 1999 36 volt EZGO TXT Freedom golf cart with existing 12 v horn, head lights, tail lights, brake lights, and turn signals.

      I went with this system as it was advertised as a kit to replace existing lead acid batteries and batteries would fit in existing rack without need for modification or additions.

      Not exactly plug and play but close, new meter installation, and additional 12 volt converter and wires not included, battery hold down modification needed. Wire connectors for converter needed. Why not include these in kit?

      An installation video could help in decision to purchase. I gleaned as much as I could from amature youtube videos of other battery brand conversions but still had questions.

      needed to make cutouts for battery bolt sockets in Battery hold down.

      battery holddown bolts needed fill spacers as threads not deep enough for new battery height.

      bolts verses battery post and nuts design meant installer must wrangle up to four wires while also attempting to seat the bolt.

      why exactly is a new charger needed?

      new charger has shorter cords than old charger so extension cord may be required.

      great fantastic support for installation questions and warranty battery replacement issue.

      packaging great

      Battery management system reset instructions needed ( plug in charger or possibly disconnect negative battery cable will reset?)

      I experienced a battery shutdown of sufficiently charged batteries (caused by bms overload?). This leaves me with concerns about possible failure away from charger and/or electric power. Need better bms reset rather than charging to reset system.

      Plus and Minus could be better marked on battery for better visibility.

      Battery comes with handles for easy installation without need for battery strap.

      I was concerned about being able to lift out old batteries but was able to with use of battery strap.

      Company is committed to customer satisfaction and support. Received prompt full refund when it was determined this set was not suitable for power draw of my cart.

      As Advertised - I Am One Happy Customer

      I spent several weeks researching whether to convert to lithium batteries and I could never get off the fence. I attempted to contact two top rated suppliers during that time and I aways got “the machine” telling me that they were unable to answer my call; however, I could go on-line etc. Needless to say, I was not pleased or impressed. I then came across the Patriot Power Source website. Unlike the other websites, I got the impression that the company was customer focused and not sales driven. I called and like the website said, I talked with Trey. I explained my situation to him and Trey explained the benefits of lithium over lead acid. Not once did he push me to buy lithium telling me that in my case it was really a personal choice because both would work for me. That did it for me … I got my credit card out, placed my order, and before submitting my order I called back. Trey answered I told him what I had in my cart and whether I needed anything else. He said I was good. Two days later I had my batteries as he said I would. I installed them and I haven’t regretted my choice one second.
