Measure the voltage and polarity of the two strings before you connect them. You can get sparks if the batteries are at different levels of charge (100% vs 50% state of charge). Also, if there is a "bad cell" in one string, can make a problem too.

How do you wire a 48 volt golf cart with batteries?
To wire a 48 volt golf cart with six 8V batteries, start by hooking the positive terminal of the first battery one to the negative terminal of the next battery. See the picture above for reference. Repeat this until all six batteries are hooked up.
How do I know if my golf cart is 36V or 48V?
To determine whether your golf cart is 36V or 48V, follow these steps: Lift up the seat to view the battery compartment. Count the number of holes on each battery. You may need to remove the battery cap to see the holes. Multiply the number of holes by 2 to determine the golf cart battery voltage.
What are the pros and cons of a 48 volt golf cart?
1 They are easily converted into hunting buggies or offroad carts. 2 They use 1/3 less amperage than 36 Volt carts, so they are more efficient. 3 Parts, especially upgrades, are more readily available for 48 Volt systems. 4 Golf carts with 48 Volt systems have higher resale values.
How old are 48V golf carts?
Here are are the manufacturing years that some of the most popular golf carts starting manufacturing 48V carts: Club Car - Club introduced their 48V system in 1995. EZGO - EZ-GO introduced their 48V system in 2008. Yamaha - Yamaha introduced their 48V system in 1995. How Old Are 36V Golf Carts?
Why is my battery sparking when I hook it up?
Sparking from a battery is perfectly normal. As long as the sparks aren't massive, they don't come with smoke, and it only sparks when connections are made, there's nothing to worry about.
Do you hook up positive or negative first on golf cart?
To connect six 6 volt batteries together in series, start with the main positive or negative of the battery bank. For this example, start with the battery bank main positive to connect six 6 volt batteries in series to form a 36 volt bank.
Why are my golf cart batteries sizzling?
The reason behind the bubbling or gurgling sound of the golf cart batteries is the gases that are present in the batteries. When charging your golf cart batteries, the amperage exceeds the level of the natural absorption rate, which could later cause the battery to overheat.
How do you hook up a 48v golf cart battery?
The main positive lead for the battery bank coming from the frame of the cart will connect to the positive terminal of the first battery in the bank. Then, connect a cable from the negative terminal of the first battery to the positive terminal of the subsequent battery in the bank.
How are electric golf carts wired?
Technically, most electric golf cart battery banks use series wiring. The 36-volts club car golf cart wiring requires a set of six batteries of 6 volts capacity each. You will also need five equal size connection cables.
What does it mean when a battery bubbles?
When charging amperage exceeds the level of the natural absorption rate, the battery may overheat, causing the electrolyte solution to bubble creating flammable hydrogen gas. Hydrogen gas, when combined with oxygen from the air, is highly explosive and can easily be ignited by a spark. Yes. You shouldn't boil them.
Can a golf cart battery explode?
When batteries run dry, they can smoke and even explode. With each battery packing the explosive power of a grenade, the potential danger is a real threat. In order to prevent this, it is essential to check your golf cart batteries on a regular basis.
How many volts should a 48v golf cart have when fully charged?
The target voltage for a 48 volt charger for AGM or some flooded batteries is 2.4 to 2.45 volts per cell, which is 57.6 to 58.8 volts.
