Can I swap six 8 volt batteries with four 12 volt batteries in a 48v system

can i put 4 12 volt batteries instead of 6 8volt batteries thanks

Yes, the main difference you’ll notice will be in the capacity (amp-hours) of the batteries. 8 volt golf cart batteries usually have a capacity of about 170 to 200 Ah, while a 12 volt battery typically ranges between 100 to 150 Ah, depending on the model. With the six 8 volt setup, you might have a total of around 1020 to 1200 Ah (6 x 170Ah = 1020 Ah or 6 x 200Ah = 1200 Ah). With the four 12 volt setup, you might have a total of 400 to 600 Ah (4 x 100Ah = 400 Ah or 4 x 150Ah = 600 Ah). This means your new setup may lower the overall battery capacity, which could result in shorter run times between charges, assuming you’re using the same types of batteries.

The reduced capacity could translate into shorter trips or less time on the course or around your property. The 12 volt batteries simply don’t have the same energy storage as the six 8 volt batteries. For example, if you were able to drive up to 30 miles with the six 8 volt batteries before needing to recharge, you may only get 20-25 miles with the four 12 volt batteries, depending on the total amp hour rating of the 12V batteries you select. Of course, this is a general estimate, and factors like terrain, weight load, and driving style will affect these numbers.

Voltage itself remains constant in both setups (48V), so there shouldn’t be a noticeable drop in speed or power output, assuming the batteries are of good quality. The motor will still receive 48 volts, and your cart will continue to operate at its standard performance levels, just with a lower capacity to store energy for longer distances. However, if you go with batteries that are too small in terms of amp hours, you may notice a decrease in overall power when climbing hills or carrying heavy loads, as the batteries may not be able to sustain the required power draw for extended periods. Be sure to measure your battery compartment and check the dimensions of the 12V batteries to avoid any fitting issues.
