Series means connecting a negative terminal of one battery to the positive terminal of another battery to increase the voltage. In off grid wind and solar power systems the greater the direct voltage for charging the batteries the lesser energy is lost along the cables.

Connecting batteries in series and parallel. Series parallel connection is when you connect a string of batteries to increase both the voltage and capacity of the battery system. Connect the other end to the positive terminal of the second battery. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage. A battery word equation and special note. Take another wire and connect the negative post of the first battery to the negative post of the second battery. Hence when charging these batteries it is important to utilize a charger that satisfies the 12 volt capacity that is necessary for both the 6 volt batteries connected in series.
When connection 6 volt batteries together it is recommended to use thick diameter cable. How to connect lithium batteries in parallel and series. For example you can connect six 6v 100ah batteries together to give you a 24v 200ah battery this is achieved by configuring two strings of four batteries. Connecting batteries in series parallel to increase battery system capacity. 20 gauge excelene welding cable has high flexibility and is rated for 600 volts. Combining the parallel connection with series connection we will double the nominal voltage and the capacity.
Always use heavy duty wires when connecting batteries in parallel. The basic concept is that when connecting in parallel you add the amp hour ratings of the batteries together but the voltage remains the same. Two 6 volt 45 ah batteries wired in parallel are capable of providing 6 volt 9 amp hours 45 ah 45 ah. B1 pos to b2 pos and b1 neg to b2 neg battery capacity x number of batteries battery bank capacity. Connect your positive and negative wires to one battery and run your application. A parallel connection on the other hand means connecting like.
Series connection increases battery voltageparellel connection increases battery capacity. Connecting in parallel increases amp hour capacity only. To connect batteries in parallel the positive terminals are connected together via a cable and the negative terminals are connected together with another cable until you reach your desired capacity. So for example a 24v system is better than a 12v system.
