I’m going to show you how to wire up batteries in series and in parallel .These are for lead acid 12-volt batteries.

They’re 18 amp hour and you can arrange them in different combinations to get different voltages. Individually there are all 12 volts but if you wire two together and with a little jumper you can get 24 volts or 36 volts for 3 batteries or 4 batteries for 48 Volts.

Before we get started, what you need to do is to sit on a dry carpet to isolate yourself from the ground. This will keep you safe from any electronic shock while we conduct the setup.

1. Series Setup

The first thing you want to do is go from the negative to the positive on the first two batteries with a jumper. This is a series setup which makes this array 24 volts.

If you check from the positive to the negative on the terminals(follow the picture) that’s your 24 volts nominal or 25.4 volts.

If you connect the next jumper from the negative terminal to the positive terminal, you should have approximately 36 volts between the terminals.

2. Parallel Setup

I’m going to show you now how to hook up 24 volts in parallel. We will use what we have in the previous setup. We already have one 24 volt array and I’m going to make another 24 volt array by connecting negative terminal of one battery to positive terminal of the other battery.

Eventually, we have 24 volts and 24 volts. If you check the voltage, we’ve got 25.4 or a nominal 24 volts for one array and for another array, we have 25 or approximately 24 volts.

The next step is to connect two 24 Volts arrays in parallel. By doing that, you can double your amperage or your runtime.

I’m using a red wire for the positive side. So now we have four batteries individually 12 volts each. We connected two in series making 24 volts and two in series here making 24 volts.

For parallel setup, we connect positive to positive terminal and negative to negative terminal of two 24 Volts series. This will double the runtime or to increase the amperage.
