4 Common Club Car Onward Lithium Problems And Their Solutions

Troubleshooting and fix for Club Car Onward Lithium Problems 

Any golf cart with lithium batteries can suffer from some issues as time passes by and the same goes for Club Car Onward. 

Despite its reliability, many users have complained about some battery problems. As a user, you must know about these common issues and how you can fix them.

1- Overheating


One of the most common issues with lithium batteries is overheating. The lifespan of lithium batteries can be severely shortened by excessive heat. 

Additionally, lithium batteries that have overheated may operate poorly and have trouble maintaining a constant power output, which will reduce acceleration. 

The overheating mostly occurs when you are charging the battery. Hence, To avoid overheating and reduce the chance of battery connection problems, adequate ventilation during battery charging is essential.

For optimum charging, temperatures between -4 and 113 degrees Fahrenheit are advised. 

2- Rapid Draining

rapid draining batteries.

A fully charged Club Car battery with a 36-volt battery design normally delivers a range of around 30 miles, whereas a 48-volt battery setup can offer a distance of 40–45 miles. 

Low voltage can trigger the fuel pump to feed fuel to the combustion engine at a slower pace, which causes the vehicle to accelerate slowly.

There can be many reasons for this issue, starting from old damaged batteries to uncharged batteries and many more.

So, at first try to recharge the battery using a working battery and if the battery still doesn’t work you will need to replace the battery. 

Also check if the alternator is working properly as sometimes alternators can also cause rapid draining batteries.

3- High Voltage Electrocution
