Most modern golf carts use lithium-ion batteries instead of older lead-acid models. Lithium batteries generally last longer, charge faster, are lighter weight, and require less maintenance. It’s understandable why these batteries are so popular with current models, and it’s a good idea to know how to take care of them when it comes to your cart. Here are some of BigBattery’s tips to properly charge a golf cart with lithium batteries so you can get the most out of their lifespan.
Mind the Temperature
It’s always good to understand how well batteries handle certain temperatures so you can charge them in an environment that isn’t outside optimal parameters. Thankfully, lithium batteries have a much wider temperature range than lead-acid batteries, which makes it easier to maintain a comfortable atmosphere when charging or discharging.
It’s best to store lithium batteries in a place between 32 and 113 degrees Fahrenheit. You shouldn’t need to worry about overheating, but it helps to charge your batteries in a warmer area during the winter to prevent any damage.
Avoid Overcharging
Overcharging is a serious problem for batteries. Forcing an overcharge often dramatically reduces your battery’s lifespan, and extensive overcharging may result in your battery struggling to hold a charge for as long as it used to, let alone other potential long-term damage internally.
Fortunately, most lithium batteries and chargers come with a battery management system (BMS) that automatically stops the flow of current when the battery is fully charged. One tip to properly charge a golf cart with a lithium battery is to avoid leaving the charger on overnight, even with a BMS, to charge your battery.
Charge Before and After Neutral Periods
It’s normal for a battery to go through a natural discharge when you’re not using it for an extended period of time. It’s always a good idea to fully charge your battery before putting it into storage to reduce the risk of draining it more than necessary. When you bring your cart out to use again, we suggest charging the battery before driving so that you start with a full charge.

Frequently Asked Questions
How long do LiFePO4 batteries last?
A quality LiFePO4 battery can commonly deliver 4,000 or more charge cycles, often roughly 10 years or longer under the right conditions. Depth of discharge, temperature, charge settings, storage habits, and the BMS all affect the result.
How many years is 4,000 cycles?
One full cycle per day is about 11 years. Three cycles per week is more than 25 years on paper, though calendar aging becomes the limit first.
What happens at the end of a LiFePO4 battery's life?
It does not suddenly stop. It loses capacity gradually. A battery rated for 4,000 cycles may be specified to keep around 80% of its original capacity at that point.
Does temperature affect LiFePO4 battery life?
Yes. High heat speeds aging, and charging below freezing can damage cells unless the battery has low-temperature protection or self-heating.
How long does a lithium battery last in an RV?
Many years, when charging sources are configured correctly and the battery is protected from freezing charge conditions. Annual cycles are often fewer than in a daily solar system, but conditions vary more.
How should I store a lithium battery?
Store it at a partial state of charge in a clean, dry, moderate-temperature location. Disconnect parasitic loads and check it periodically per the manufacturer's guidance.
