# How Many Batteries are in a 48 Volt Golf Cart?

Electric golf carts are powered by onboard battery packs, which must be replaced from time to time. Commonly, electric golf carts use 36-volt and 48-volt electric systems, although 72-volt electric golf carts are becoming more and more popular.

Electric golf cart battery packs are based on 6V, 8V, and 12V lead-acid batteries, although in recent times, 12V, 24V, 36V, and 48V golf cart lithium batteries are also manufactured. So, how many batteries are in a 48-volt golf cart?

Updated: April 18, 2024.

## Golf Cart Battery Sizes

The most popular golf cart battery sizes are:

• 6 Volts: GC2 (10 3/8 x 7 3/16 x 10 7/8 inches, 264 x 183 x 277 mm) and GC2H (10 3/8 x 7 3/16 x 11 5/8 inches, 264 x 183 x 295 mm),
• 8 Volts: GC8 (10 3/8 x 7 3/16 x 10 7/8 inches, 264 x 183 x 277 mm) and GC8H (10 3/8 x 7 3/16 x 11 5/8 inches, 264 x 183 x 295 mm),
• 12 Volts: GC12 (12 7/8 x 7 3/16 x 10 7/8 inches, 327 x 183 x 277 mm).

So, in order to make a 48-volt battery pack, one needs:

• 8 (eight) GC2 or GC2H batteries: 8 x 6 volts = 48 volts
• 6 (six) GC8 or GC8H batteries: 6 x 8 volts = 48 volts
• 4 (four) GC12 batteries: 4 x 12 volts = 48 volts

Similarly, in order to make a 36-volt battery pack, one needs:

• 6 (six) GC2 or GC2H batteries: 6 x 6 volts = 36 volts
• 3 (three) GC12 batteries: 3 x 12 volts = 36 volts

Note: using GC8 or GC8H batteries, one may create 32-volt or 40-volt battery packs, but NOT 36-volt battery packs. Should one decide to use GC8 or GC8H batteries in a 36-volt golf cart, 4 (four) GC8 or GC8H batteries equal to 32 volts, leading to an underpowered golf cart, and 5 (five) GC8 or GC8H batteries equal to 40 volts, which may damage or destroy the electric system of a 36-volt golf cart. For short, don't use GC8 or GC8H batteries in 36-volt golf carts.

Although 72-volt golf carts are not as common as 48-volt units, it is good to know that in order to make 72-volt battery pack, one needs:

• 12 (twelve) GC2 or GC2H batteries: 12 x 6 volts = 72 volts
• 9 (nine) GC8 or GC8H batteries: 9 x 8 volts = 72 volts
• 6 (six) GC12 batteries: 6 x 12 volts = 72 volts

Note: when connecting batteries in series, if possible, always use the same battery models of the same manufacturer, preferably from the same batch.

## Counting the Batteries and Water Holes

If you have issues with your battery pack, measuring its voltage using a digital multimeter provides current voltage of the battery pack, but finding nominal voltage of the batter pack may be little bit harder.

For example, you may measure 27.6 volts, but you are not sure if your golf cart is a 36V or 48V vehicle.

The easiest way of figuring out the exact golf cart voltage is by looking at the - documentation. However, after some time, it may be hard to find such documents, and all the markings on the golf cart may be covered by rust and dirt.

So, in order to find out the exact electric golf cart voltage, open the battery compartment, check the batteries' specifications (volts, capacity, BCI Group) and count the batteries.

If such data is unreadable, count the batteries and, if they are present, water fill holes - each flooded/wet lead-acid battery features one water fill hole per one battery cell (~2 volts per cell).

So, flooded GC2/GC2H batteries feature 3 water fill holes for a total of 6 volts per battery, GC8/GC8H batteries feature 4 water fill holes for a total of 8 volts per battery, and GC12 batteries feature 6 water fill holes for a total of 12 volts per battery.

Unlike wet lead-acid batteries, AGM and Gel-Cell lead-acid batteries don't require the user to fill the water during use, since they are maintenance-free batteries. Nonetheless, they (or at least AGM batteries) commonly feature fill holes on top of the batteries which can be counted as well in order to determine the battery voltage.

## Lithium 48 Volts Golf Cart Battery Packs

Lithium batteries offer many advantages over lead-acid batteries, including weight savings, faster recharging, a larger number of supported charging/discharging cycles, excellent 100% DoD recovery, and similar.

On the other side, lithium golf cart batteries are more expensive, at least initially.

If your 48V golf cart is powered by Lithium Iron Phosphate (LiFePO4) battery (or batteries), it has:

• 4 (four) 12 volts lithium batteries: 4 x 12 volts = 48 volts
• 2 (two) 24 volts lithium batteries: 2 x 24 volts = 48 volts
• 1 (one) 48 volts lithium batteries: 1 x 48 volts = 48 volts

In recent times, 48 volts lithium batteries are becoming more and more popular for 48 volts systems and 24 volts lithium batteries for 72 volts systems.

Long Story Short: If your golf cart has a 48-volt electric system and you have lead-acid batteries, then you have 8 (eight) 6-volt batteries, or 6 (six) 8-volt batteries, or 4 (four) 12-volt batteries.

If such a golf cart is powered by lithium batteries, then you have 4 (four) 12-volt batteries, or 2 (two) 24-volt batteries, or 1 (one) 48-volt battery.

Transitioning from lead-acid 48V batteries to lithium 48V batteries requires careful planning, but in the long run, results in a lighter vehicles, which are faster, more agile, and have a greater range.
