Typical Battery Configurations for 48 Volt Golf Carts

A 48-volt golf cart system is generally composed of multiple 6-volt or 12-volt batteries connected in series to achieve the required voltage. The most common and recommended configuration involves using 6-volt deep cycle batteries due to their balance of capacity, longevity, and cost-effectiveness.

When using 6-volt batteries, the standard setup typically includes eight batteries connected in series:

  • Each 6-volt battery contributes 6 volts.
  • Connecting eight in series adds up to 48 volts (6V × 8 = 48V).
  • These batteries are usually rated between 200 to 225 amp-hours (Ah), providing sufficient energy storage for typical golf cart usage.

Alternatively, some golf carts use four 12-volt batteries connected in series:

  • Each battery provides 12 volts.
  • Four in series produce the required 48 volts (12V × 4 = 48V).
  • 12-volt batteries are heavier and generally have lower total amp-hour capacity compared to the 6-volt deep cycle batteries used in an 8-battery setup.

The choice between 6-volt and 12-volt batteries often depends on the specific golf cart model, budget, and desired performance characteristics.

Battery Arrangement and Wiring

To achieve 48 volts, batteries must be wired in series. This means connecting the positive terminal of one battery to the negative terminal of the next, continuing this pattern across all batteries in the battery bank. This series connection increases voltage while the amp-hour capacity remains equal to that of a single battery.

Key points about wiring and arrangement:

  • Series wiring increases voltage: Connecting batteries in series adds their voltages but not their amp-hour ratings.
  • Amp-hour capacity remains constant: The total capacity equals the capacity of one battery in the series.
  • Parallel connections increase capacity: If more capacity is needed, parallel wiring of series strings can be used, but this is less common in standard golf cart setups.
  • Proper terminal maintenance: Ensuring clean and tight connections reduces resistance and improves performance.
