Why Not All Lithium Batteries Are Created Equal \u2014 and How Go Lithium has been Raising the Bar For a decade<\/em><\/h3>\n
\n

Why all Lithium Batteries aren’t Created Equal, and How Go Lithium has been Raising the Bar For a decade?\u00a0 Most race cars ran large, heavy lead Acid and AGM batteries that \u201cjust worked.\u201d They were forgiving and durable but woefully inadequate in a modern racing environment.<\/span><\/span><\/span><\/span><\/p>\n

Racers are always in search of a performance advantage and the most forward thinking teams began switching to lithium batteries. The results were impressive. Removing 30 to 40 pounds instantly and doubling or even tripling the capacity of their old lead acid counterparts…But with that shift came a wave of questions, concerns, and a few very high-profile fires.<\/p>\n<\/div>\n

<\/div>\n
Lithium batteries can be perfectly safe in a race car. But only when they\u2019re built correctly, wired correctly, and charged correctly. And that\u2019s where many racers get into trouble.

The Real Reason Lithium Fires Happen<\/strong>You\u2019ve seen the pit videos: smoke roaring out of a trunk, flames hot enough to melt aluminum, crew guys scrambling with extinguishers. When a lithium battery fails, temperatures can spike to over 2,000\u00b0F<\/strong>, and the fire doesn\u2019t behave like anything from an AGM.<\/h2>\n

But here\u2019s the part most racers don\u2019t know:<\/p>\n

Most lithium battery fires in racing come from the car, not the battery.<\/strong>
They\u2019re caused by:<\/p>\n

    \n
  • \n

    Undersized wiring<\/p>\n<\/li>\n

  • \n

    Bad or missing grounds<\/p>\n<\/li>\n

  • \n

    Overcharging<\/p>\n<\/li>\n

  • \n

    Wrong charger<\/p>\n<\/li>\n

  • \n

    Cheap imported lithium cells<\/p>\n<\/li>\n

  • \n

    No real BMS (Battery Management System)<\/p>\n<\/li>\n<\/ul>\n

    AJ from GO Lithium told us one of the biggest problems he sees:
    \u201cRacers want to go lightweight on the battery AND lightweight on the wiring.\u201d<\/strong><\/p>\n

    Many racers are trying to run 4-gauge wire<\/strong> on a 16V lithium setup.
    That might be fine for AGM \u2014 not lithium.<\/p>\n

    AJ’s recommendation?
    \u201cStart at 0-gauge. Don\u2019t go smaller than 2-gauge. Ever.\u201d<\/strong><\/p>\n

    Lithium batteries deliver power instantly<\/em>. If the cable can\u2019t safely move that current, the heat finds a new path \u2014 and something melts. This is where some lithium batteries have fail-safes, and others do not.<\/p>\n

    \"\"<\/p>\n

    AGM vs. Lithium: The Truth Behind the Switch<\/strong><\/h2>\n

    AGM batteries are tanks. They tolerate:<\/p>\n

      \n
    • \n

      Overcharging<\/p>\n<\/li>\n

    • \n

      Heat<\/p>\n<\/li>\n

    • \n

      Vibration<\/p>\n<\/li>\n

    • \n

      Weak grounds<\/p>\n<\/li>\n

    • \n

      Cheap chargers<\/p>\n<\/li>\n<\/ul>\n

      Lithium batteries do not<\/strong>.<\/p>\n

      They are lighter, more powerful, and hold voltage like a rock \u2014 but need an electrical system capable of handling the additional power. That means:<\/p>\n

        \n
      • \n

        Correct wiring size<\/p>\n<\/li>\n

      • A quality alternator and starter<\/li>\n
      • \n

        properly matched lithium cells<\/p>\n<\/li>\n

      • \n

        A high quality and fully comprehensive batter. management system<\/p>\n<\/li>\n

      • \n

        Proper mounting<\/p>\n<\/li>\n<\/ul>\n

        This is where the difference between \u201crace-grade lithium\u201d and \u201cpowersports lithium\u201d becomes massive.<\/p>\n

        GO Lithium\u2019s Take: Building Them the Right Way Matters<\/strong><\/h2>\n

        During our interview, AJ emphasized one thing repeatedly:<\/p>\n

        \u201cWe not only engineer, but hand-build every battery. We control everything.\u201d<\/strong><\/p>\n

        Most lithium batteries sold for racing are mass-produced overseas for pennies with:<\/p>\n

          \n
        • \n

          Cylindrical \u201cAA-style\u201d cells soldered together<\/p>\n<\/li>\n

        • \n

          Spray-foam (flammable) in the case<\/p>\n<\/li>\n

        • \n

          Utilize the cheapest BMS system available<\/p>\n<\/li>\n

        • \n

          No cell matching<\/p>\n<\/li>\n

        • \n

          No comprehensive bench testing<\/p>\n<\/li>\n

        • \n

          No real world track testing<\/p>\n<\/li>\n<\/ul>\n

          Go Lithium takes the opposite approach:<\/p>\n

            \n
          • \n

            The type approved by the UN to be in peoples houses for solar power.<\/p>\n<\/li>\n

          • They UN test their cells to insure they maintain the highest safety standards and extensively track test every design before it is offered for sale. Before buying a lithium battery, call the manufacturer and ask if their cells have been UN tested and approved.<\/li>\n
          • \n

            Uses prismatic cells<\/strong> (rectangular blocks) that are then built into their own safety casings<\/p>\n<\/li>\n

          • \n

            They have also, which is totally unique in the industry, engineered out any internal cables. No wires or cables inside \u2014 everything is bolted<\/strong>, not soldered<\/p>\n<\/li>\n

          • \n

            Each cell has a \u201cbust plate\u201d like a blower in the event of a catastrophic event<\/strong><\/p>\n<\/li>\n

          • \n

            Batteries can be rebuilt<\/strong><\/p>\n<\/li>\n

          • The 500+ AMP capable BMS seamlessly handles any overcharge, over-discharge, and cell balances automatically.<\/li>\n
          • Every battery is assembled and checked by hand in Minnesota<\/li>\n
          • \n

            Every battery is assembled and checked by hand in the U.S.<\/p>\n<\/li>\n<\/ul>\n

            This is the type of construction that allowed the NHRA Safety Safari<\/strong> to try \u2014 and fail \u2014 to get a GO Lithium battery to ignite during suppression testing.<\/p>\n

            That\u2019s the kind of test result racers want to hear.<\/p>\n

            What Racers MUST Ask Before Buying ANY Lithium Battery<\/strong><\/h2>\n

            Whether choosing Go Lithium or another brand, racers need to ask:<\/p>\n

            HAS THE CELL BEEN UN TESTED AND APPROVED? Then move to next questions.\u00a0<\/strong><\/p>\n

            2. What type of cells are used?<\/strong><\/h3>\n

            Prismatic > cylindrical cells for motorsports use.<\/p>\n

            3. Does it have a real BMS?<\/strong><\/h3>\n

            Ask specifically:<\/p>\n

              \n
            • \n

              Does it prevent overcharging?<\/p>\n<\/li>\n

            • \n

              Does it balance cells?<\/p>\n<\/li>\n

            • \n

              Does it shut down if something\u2019s wrong?<\/p>\n<\/li>\n<\/ul>\n

              4. What wire size is required?<\/strong><\/h3>\n

              If the company says 4-gauge\u2026
              Walk away.<\/p>\n

              5. What alternator voltage is safe?<\/strong><\/h3>\n

              Overcharging is the #1 killer of lithium batteries.<\/p>\n

              6. How should it be stored off-season?<\/strong><\/h3>\n

              Lithium does NOT like being drained to zero.<\/p>\n

              7. Does the company actually test their batteries?<\/strong><\/h3>\n

              Not lab testing \u2014 drag racing testing<\/strong>.<\/p>\n

              \"\"<\/p>\n

              Racers Aren\u2019t Wrong to Be Concerned \u2014 They\u2019re Just Not Informed<\/strong><\/h2>\n

              Lithium batteries are not dangerous by nature.
              They\u2019re dangerous when:<\/p>\n

                \n
              • \n

                Cheap cells are used<\/p>\n<\/li>\n

              • \n

                Inferior BMS systems fail<\/p>\n<\/li>\n

              • \n

                Incorrect chargers are plugged in<\/p>\n<\/li>\n

              • \n

                Racers run too-small wire<\/p>\n<\/li>\n

              • \n

                Alternators overcharge them<\/p>\n<\/li>\n

              • \n

                Or the battery is allowed to die repeatedly<\/p>\n<\/li>\n<\/ul>\n

                When done correctly, lithium is just as safe as AGM \u2014 and far lighter.<\/p>\n

                When done incorrectly, it can become the hottest fire in the pits, unless you have a battery that has the right type of lithium and is properly built with fail-safes.<\/p>\n

                Final Thoughts: Lithium Is Safe\u2026 When You Pick the Right One<\/strong><\/h2>\n

                Racers are always chasing lighter and faster. Lithium batteries fit that mindset perfectly \u2014 but lithium requires more respect, more knowledge, and a better-quality product.<\/p>\n

                The takeaway for racers is simple:<\/p>\n

                All lithium batteries are not created equal.
                Ask the right questions.
                Choose the right wiring.
                Buy from a company that builds them for motorsports\u00a0<\/strong><\/p>\n

                Whether you choose GO Lithium or any other brand, understanding the technology is the difference between dropping weight\u2026
                and dropping your guard.<\/p>\n
