How to Wire up a Battery to Increase Power or Runtime.
Wiring Batteries in Series and Parallel is done to attain different voltages that is higher than the individual battery voltages. Each battery has an approximate voltage of 12V when charged to capacity. However, two or more batteries can be connected to get 24 or more volts. Series connection entails connecting the negative terminal to the positive terminal of the battery. The series setup results to a 24 voltage from the two batteries each having 12 volts. The voltage is measured using a voltmeter by placing one end to positive terminal of one battery then the other end to the negative terminal to the second battery.
Series-parallel connection can also be done through parallel wiring batteries that have been connect in series. Parallel connection is done through wiring negative terminal of one battery to another negative terminal of a second battery. This connection is done to increase performance or the run time of a device. If four batteries are connected with two sets connected in parallel then each set connected to the other in parallel, the measurement in each set will remain 24 volts.
