Here's a step-by-step guide on how to connect four 6-volt batteries in series to get 12 volts:
1. Gather the necessary materials. You will need the four 6-volt batteries, some battery connector clips or wires, and a voltmeter to test the output voltage.
2. Connect the batteries in series.
- Connect the positive terminal of the first battery to the negative terminal of the second battery.
- Connect the positive terminal of the second battery to the negative terminal of the third battery.
- Connect the positive terminal of the third battery to the negative terminal of the fourth battery.
3. Test the output voltage. Use the voltmeter to measure the voltage between the positive output (positive terminal of the first battery) and the negative output (negative terminal of the fourth battery). The voltmeter should read 12 volts if the batteries are connected correctly.
