What you should know when considering a Lithium Battery Conversion
 
GEM 98-15 Battery
What are the main benefits of a Lithium Battery vs a Lead battery in a GEM Car:
  • High quality Lithium paks can last 3 to 4 times longer (or more) than a lead battery:
    • Lead batteries have ​~500 charging cycles vs a Lithium that has ~2000 charging cycles
    • Even after 2000 charging cycles a lithium pak can still operate at 80% of its power.
    • A quality lithium has an expected life of 10-12 (or more) years.
  • Longer range - Lithium paks can provide 25% to more than 200% more range depending upon lithium pak size.
    • Due to their smaller size, you can put more battery power into the same space used by lead batteries when switching to Lithium.​
    • Lithium voltage remains higher than lead batteries as they are being used. For a example a lead battery at 50% usage will have substantially reduced voltage and amperage - in fact it could put the GEM car into turtle mode. While a lithium would demonstrate power/performance comparable to a fully charged battery - Generally, a lithium will run as good as it does at 50% charge as it does at 100% .charged
  • Lithium batteries can be left for long periods of time without charging.
  • Lithium batteries are significantly lighter than lead batteries.
