You typically need either four 12V lithium batteries or two 24V lithium batteries connected in series to make a 48V system for a golf cart. Alternatively, using a single integrated 48V lithium battery is increasingly popular due to its simplicity, space efficiency, and ease of installation, often provided by manufacturers like Redway Battery.
How Many Lithium Batteries Do You Need for a 48V Golf Cart?
To achieve a 48V system, you usually require four 12V lithium batteries or two 24V batteries connected in series. The exact number depends on your golf cart’s voltage requirement and battery capacity, but these configurations are standard practice for optimal performance.
What Are the Common Battery Configurations to Achieve 48V?
48 volts can be attained by wiring batteries in series, meaning the voltages add up while the amp-hours remain the same. Common configurations are:
- Four 12V batteries in series
- Two 24V batteries in series
- A single integrated 48V lithium battery pack
Configuration options differ based on manufacturer specifications and user preferences.
Why Should You Choose Lithium Batteries Over Lead-Acid?
Lithium batteries provide higher energy density, longer lifespan, and much lighter weight compared to traditional lead-acid batteries. They offer faster charging, require less maintenance, and deliver consistent power, improving golf cart efficiency and performance.
How Do You Properly Wire Lithium Batteries in Series for 48V?
Wiring batteries in series involves connecting the positive terminal of one battery to the negative terminal of the next, summing the voltage across the chain. For example, in four 12V batteries, the total voltage equals 4 x 12V = 48V, suitable for your golf cart.

What Are the Benefits of Using a Single Integrated 48V Lithium Battery?
A single integrated 48V battery reduces installation complexity, saves space, and minimizes weight. It offers a cleaner setup with fewer connections, lowering potential failure points and easing maintenance. Brands like Redway Battery specialize in such integrated solutions for golf carts.
How Do You Calculate Battery Capacity to Meet Runtime Needs?
Runtime depends on amp-hour (Ah) capacity and energy consumption. For example, a golf cart requiring 10 amps for 5 hours needs a battery with around 50Ah capacity at 48V. Always account for application demand and desired drive time to select correctly sized batteries.
Runtime Calculation Chart
| Drive Current (amps) | Required Runtime (hours) | Minimum Battery Capacity (Ah) |
|---|---|---|
| 10 | 5 | 50 |
| 15 | 4 | 60 |
| 20 | 3 | 60 |
How Do Controller Amperage and Modifications Affect Battery Requirements?
Higher amperage controllers demand batteries that can deliver increased current without damage. Modifications that boost cart speed or power draw will require lithium batteries with higher discharge rates and amp-hour ratings to maintain performance and protect battery health.
What Are the Weight and Space Considerations for Different Battery Setups?
Multiple smaller batteries increase weight and take more space, potentially impacting golf cart handling and storage. Lithium alternatives reduce weight by up to 50% compared to lead-acid, and single integrated packs further optimize space usage, making the cart lighter and more agile.
How Do You Maintain and Care for Lithium Batteries in Golf Carts?
Lithium batteries require minimal maintenance, such as periodic charging, avoiding deep discharge, and storing in a cool, dry environment. Using a proper lithium-compatible charger, like those recommended by Redway Battery, ensures longevity and safety.
How Do Environmental Conditions Impact Lithium Battery Performance?
Extreme temperatures affect lithium battery efficiency. High heat accelerates degradation, while cold reduces capacity temporarily. Proper thermal management and usage within manufacturer recommended temperature ranges optimize longevity and reliability.
What Should You Know About Installation and Safety When Upgrading Batteries?
Correct wiring and secure mountings are essential to prevent shorts or damage. Always follow manufacturer instructions and use compatible chargers. Lithium batteries should include built-in Battery Management Systems (BMS) to protect from overcharge, over-discharge, and thermal events.
