Most battery for golf carts includes lead-acid and lithium 2 types. Typically, they come from the factory with lead-acid batteries in 6V, 8V, or 12V configurations, wired in series to create a 36V or 48V system. For longer run time, lower maintenance, and extended lifespan, we recommend upgrading to lithium iron phosphate (LiFePO4) batteries. LiTime offers 36V and 48V lithium golf cart batteries for optimal performance.
When you receive your battery, please note that it may have a low State of Charge (SOC) due to transportation and storage. For optimal performance, we recommend charging the battery immediately to avoid over-discharge.
For Bluetooth batteries, they may arrive in an off state with a virtual voltage of 3V-5V at the terminals. This is normal and can be resolved by using an AC-DC lithium battery charger or MPPT solar charge controller to charge for 3-10 seconds, which will activate the battery for normal use.
If you plan to store the battery for an extended period without use, charge it to a SOC of 30% to 50% and perform maintenance every three months. This will help preserve its functionality and performance over time.
To find your golf cart's voltage, check your owner’s manual, search for the technical specifications online, or locate the technical/serial number sticker on your vehicle, which usually lists the voltage. Most golf carts are either 36V or 48V.
If you're unable to find the voltage using these methods, you can open the battery compartment and calculate it yourself. Each battery should have its voltage labeled. Multiply the voltage of a single battery by the number of batteries in the bank to determine the system voltage. For example, eight 6V batteries would give you a 48V system.
If you need assistance determining your golf cart's voltage, feel free to contact us at service@litime.com with a photo of your battery tray, and we'll help you figure it out.
Due to the different charging requirements compared to lead-acid batteries, we recommend using a LiFePO4 lithium battery charger for charging.
Here are the charging options for LiTime lithium golf cart batteries:
1)AC-DC lithium battery charger: Choose a charger with the correct charging voltage to safely charge the battery.
2) Solar panels: When using solar panels, ensure you connect a solar charge controller for safe charging.
3) Alternator/Generator:
a. If your alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery.
b. If your alternator or generator supports AC output, use a compatible battery charger as recommended in the product manual to safely connect the battery and generator.
Golf cart batteries can handle light rain/splashes, but direct spraying or submersion isn’t recommended; moisture can damage terminals and electronics. while a lithium ion battery for golf cart is often rated IP65 (dust-tight, resistant to water jets)—still not meant for immersion.

The right Ah for a golf cart (and any lithium ion battery for golf cart) depends on cart voltage (36V/48V), expected range, terrain, and load—higher-voltage carts typically need fewer Ah.
A practical method is estimating Ah from driving needs; for example, a 48V cart going ~15 miles at ~20Ah/mile would target about 300Ah.
Calculation steps and LiTime range references are summarized here:[Full Guide] How Many Ah Batteries Do I Need for a Golf Cart
A golf cart can be converted from lead-acid to lithium by matching the cart’s system voltage (commonly 36V or 48V), installing the lithium pack securely, and using a lithium-compatible charger; carts with 12V accessories may also need a DC-DC converter.
The process typically includes assessing voltage and capacity needs, disconnecting power (tow mode if available) and removing lead-acid batteries, cleaning/inspecting the tray and cables, installing the lithium pack, wiring positive-to-positive and negative-to-negative (following approved series/parallel diagrams), confirming charger compatibility, then verifying voltage and performing a short test run.
Water should be added after charging, using distilled water only.
Charging expands electrolyte, so filling before charging can cause overflow; the water level should cover the plates without overfilling. For maintenance-free operation, a lithium battery for golf cart avoids watering altogether.

Although it is generally safe to leave a LiFePO4 battery on the charger, as both the charger and the battery itself have a BMS to prevent overcharging, it’s still best to monitor the charging process.
Once the battery is fully charged, disconnecting it promptly is recommended to avoid unnecessary damage.
For convenience, LiTime offers chargers with Anderson connectors, allowing you to stop charging simply by unplugging the Anderson connector without needing to separate the battery terminals from the screws after charging.
However, for optimal safety, it’s advised to first unplug the AC plug before disconnecting the Anderson connector.

With proper maintenance, lead-acid golf cart batteries often last about 4–6 years, while a lithium battery for golf cart typically lasts longer and requires no watering.
For flooded lead-acid batteries, add distilled water after charging—charging expands electrolyte, and low water can expose plates, causing sulfation and shortening lifespan; the level should cover plates without overfilling (about 1/4–1/2 inch above plates).
