Ve to ve to ve to ve adds the voltages together but the ah capacity remains the same. Then with the two groups wire them together positive to positive and negatives to negative to give you 500ah.

How to wire a battery bank. To use the designer follow these 4 simple steps. As a general rule connecting batteries in series ie. You can connect the positive of your charge controller andor dc to ac inverter to any positive point in the battery bank though it is best to make this connection in the middle of the set of batteries rather than from one end as shown. Wire each group positive to negative will give you 24v on the furthest negative and positive post not wired to another battery. You can connect your load to one of the batteries and it will drain both equally. Using any eight 6v batteries group them into two groups of four.
When connecting in series amp hours dont. Connecting batteries in parallel ie. Connecting batteries in series means connecting the positive terminal of the first battery to the negative terminal of the next and so on. Batteries that are connected in parallel add up all their amp hours together allowing you to increase the total capacity of your battery bank. Detailed instructions for using the battery bank designer. To join batteries in parallel use a jumper wire to connect both the positive terminals and another jumper wire to connect both the negative terminals of both batteries to each other.
By doing this you have achieved the criteria of balanced charging each battery will draw current through exactly three interconnecting leads. Ve to ve and ve to ve combines the capacities but leaves the voltage unchanged. Create a 450 amp hour 12 volt battery bank with four 6 volt batteries demonstrated in the video using four 6 volt 225 amp hours batteries wire the first pair of batteries a1 and a2 in series to output 12 volts at 225 amp hours. Negative to negative and positive to positive. Using the most popular and widely available battery sizes this design tool can show you how to wire your battery bank. Configurations are possible for amphour capacities from as little as 300 amphours to over 4000.
Wire the second pair of batteries b1 and b2 in series to output an additional 12 volts at 225 amp hours. There are various ways that you may choose to wire together a number of batteries in order to create a battery bank to suit your requirements. The first and easiest method to achieve balanced charging is to simply reverse direction of one set of leads and wire them starting from the opposite end of the battery bank see figure 3.
