Our advice: keep your lead acid batteries until you notice less range and weaker power. When it's time to replace them, go lithium. It usually costs only a few hundred dollars more, and it can save you from paying for batteries all over again.

Prices and lifespans reflect what we see with our customers, while weight and charge times are typical figures from battery sellers. Real results depend on the battery, charger, cart and how you drive.
Why we recommend lithium
Yes, lithium can cost a few hundred dollars more. But you're buying a system that should last 8+ years, maintenance free. You also get longer range, better acceleration and torque, and reliable performance.
We're a dealer for Bolt Energy USA, whose kits come with a 12-year transferable warranty. That helps your cart keep its value: use it for as long as you like, then pass the warranty to the next buyer when you sell.
The real cost of lead acid
Lead acid needs distilled water refills, regular charging and balancing. If it isn't properly maintained, you may only get 1 to 1.5 years out of your batteries. Then you're back to square one, spending another $1,800.
Our recommendation
If your lead acid batteries are still going strong, keep using them. When you notice less range and weaker power, or if you're buying new, come out of the gate with lithium. Spend $2,200+ once, and you can stop worrying about your batteries.
Before you upgrade
Use a kit made for golf carts and matched to your cart's voltage. You may also need a compatible charger and mounting hardware.
See our lithium battery kits, or contact our upgrades team for help choosing and installing one.
