Upgrading Your Golf Cart: Converting to Lithium Batteries

Are you tired of constantly replacing your golf cart’s lead-acid batteries? It’s time to consider upgrading to lithium batteries! This game-changing conversion can breathe new life into your trusty golf cart, offering a range of benefits that’ll make you wonder why you didn’t switch sooner. Let’s dive into the world of lithium battery upgrades and discover how you can revolutionize your golf cart experience.

Why Convert to Lithium Batteries?

Switching to lithium batteries isn’t just a trendy move – it’s a smart investment that’ll pay dividends in the long run. Here’s why you should consider making the switch:

  1. Longer lifespan: Lithium batteries can last up to 5 times longer than traditional lead-acid batteries. That means fewer replacements and more time enjoying your golf cart.
  2. Improved performance: Say goodbye to sluggish starts and mid-round power dips. Lithium batteries provide consistent power output throughout your entire golf game.
  3. Reduced maintenance: No more topping up water levels or dealing with corrosion. Lithium batteries are virtually maintenance-free, saving you time and hassle.
  4. Lighter weight: Lithium batteries can weigh up to 70% less than lead-acid batteries, improving your cart’s handling and reducing wear and tear on other components.
  5. Faster charging: With lithium batteries, you can get back on the green quicker. They charge up to 5 times faster than traditional batteries.
  6. Consistent power output: Unlike lead-acid batteries that lose power as they discharge, lithium batteries maintain steady voltage until they’re nearly depleted.

Pre-Conversion Considerations

Before you rush to swap out your batteries, take a moment to assess your situation:

  1. Evaluate your current golf cart: Make sure your cart is in good condition and worth the investment of a lithium battery upgrade.
  2. Determine voltage requirements: Most golf carts run on 36V or 48V systems. Ensure you choose lithium batteries that match your cart’s voltage.
  3. Calculate capacity needs: Consider your typical usage and terrain to determine the appropriate battery capacity (measured in amp-hours).
  4. Budget considerations: While lithium batteries cost more upfront, their longer lifespan and improved performance often make them more cost-effective in the long run.

Necessary Components for Conversion

If you are asking the question of “How do I convert my golf cart to lithium?”,  you are likely overthinking it. Here’s what you need to do to convert your cart to lithium:

Here’s why it is that simple, with only 1-4 parts that you need to make sure to have, aside from the lithium battery itself:

  1. Lithium Charger

Lithium Battery Charger

The only thing that you most likely HAVE to replace is your charger. Most lithium battery bundles come with their own charger, which ensures the safety of the battery and doesn’t void the battery’s warranty.

  1. 12 volt converter
    (ex:https://www.extremekartz.com/lithium-36v-48v-to-12v-voltage-converter-30-amp-max-allied-battery/ )

If your cart does not already have one, which most older carts don’t, you will need to make sure you purchase one when you buy your lithium battery kit. Otherwise, your lights, or any other 12 volt accessories, will burn up.

3. Battery cables
(ex: https://www.extremekartz.com/2-gauge-power-cables-for-club-car/ )

Most likely, you can use your existing battery cables. And, often brand new cables are included in the lithium battery bundle. The time where it’s NOT advised to use your existing battery cables, is when you are upgrading to a lithium battery that has significantly more power. In that case, since you will have more current going through your cables, upgrading to four gauge or two gauge battery cables would be recommended.

4.  Solenoid
(ex:https://www.extremekartz.com/solenoid-400a-48v-for-high-amperage-controllers-400-amp/)

Heavy Duty Solenoid

You most likely can use your existing solenoid. However, if these two things are true, then we would recommend upgrading to a heavy duty solenoid: 

  1. Your cart and solenoid are at least six years old and/or 
  2. You are getting a more powerful lithium battery upgrade. 

The combination of these two things means that your existing solenoid will probably start failing soon, unless you upgrade it, now that your batteries can send much higher amperage to your controller.

That’s it! Converting to lithium is easy!

Step-by-Step Conversion Process

Ready to make the switch? Follow these steps for a successful conversion:

  1. Safety first: Always wear protective gear and work in a well-ventilated area. Disconnect the main power source before starting.
  2. Remove old batteries: Carefully remove your old lead-acid batteries, taking note of how they’re connected. Would recommend a lead-acid removal strap if you don’t have one.
  3. Clean and inspect: Thoroughly clean the battery compartment and inspect for any damage or corrosion.
  4. Mount new lithium batteries: Securely place your new lithium batteries in the compartment, ensuring they’re properly aligned.
  5. Connect batteries: Follow the wiring diagram provided (or online) to connect your batteries. 
  6. Install the new charger: Replace your old charger with one compatible with lithium batteries.
  7. Test the system: Carefully test all connections and power up your golf cart to ensure everything is working correctly.

Remember, if you’re not comfortable with electrical work, it’s always best to consult a professional. Your safety and the proper functioning of your golf cart should be top priorities.

Post-Conversion Considerations

Once you’ve successfully converted to lithium batteries, keep these tips in mind:

  1. Proper charging practices: Always use the correct charger and avoid overcharging or completely draining your batteries.
  2. Maintenance tips: While lithium batteries require less maintenance, regularly inspect connections and keep the batteries clean.
  3. Monitor performance: Keep an eye on your cart’s performance and battery life to ensure everything is functioning optimally.

Troubleshooting Common Issues

Even with proper installation, you might encounter some hiccups. Here are a few common issues and quick fixes:

  1. Charging problems: Ensure your charger is compatible and functioning correctly.
  2. Performance issues: Check all connections and consult your battery manual for potential error codes.
  3. BMS errors: Refer to your battery documentation for specific error codes and troubleshooting steps.
