I have an EZ go with 6 6v batteries. New batteries cost more than what I can afford. Is there a way to use 12v batteries instead??

Yes, you can use three 12 volt batteries instead of six 6 volt batteries in your 36V golf cart by wiring them in series to achieve the necessary 36 volts. While this can be a cost effective solution, it may result in shorter run times and reduced battery lifespan due to the typically lower amp hour ratings of 12V batteries compared to 6V batteries.
In your current setup these batteries are connected in series. This means the positive terminal of the first battery is connected to the negative terminal of the second battery, the positive terminal of the second battery is connected to the negative terminal of the third battery, and so on. This series connection sums the voltages of each battery, resulting in a total of 36 volts (6V + 6V + 6V + 6V + 6V + 6V = 36V) to power your golf cart.
When switching to three 12 volt batteries, the wiring configuration remains a series connection but with fewer batteries. You will connect the positive terminal of the first 12V battery to the negative terminal of the second 12V battery, and the positive terminal of the second 12V battery to the negative terminal of the third 12V battery. This series connection will also sum the voltages to achieve the required 36 volts (12V + 12V + 12V = 36V).
There are several pros to switching to 12V batteries. One significant advantage is cost efficiency; 12V batteries are often less expensive than 6V batteries, which can be a significant advantage when budget is a concern. However, there are also cons to consider. 6V batteries typically have higher amp-hour (Ah) ratings than 12V batteries, meaning they can provide more consistent power over a longer period. Switching to 12V batteries may result in shorter run times and reduced overall performance.
You should use deep cycle batteries, which are specifically designed to provide a steady amount of power over a long period and can be deeply discharged and recharged repeatedly. Unlike automotive batteries, which are designed to deliver a short burst of high energy to start a vehicle's engine and then be recharged quickly by the alternator, deep cycle batteries have thicker plates and denser active material to withstand the stresses of deep cycling.
Regardless of the size of battery, regular maintenance is key. Practice proper charging, avoid deep discharges, and check water levels to extend battery life. If you have any questions feel free to ask!
