Following this example where there are two 12v 200ah batteries connected in parallel we will therefore have a voltage of 12v volts and a total capacity of 400ah ampere hour. Take another set of batteries and wire them together in parallel as well.
Connecting Series Parallel Batteries Tutorial
Connecting two 12 volt batteries in parallel. Two 12 volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12 volt battery. Use one battery cable. Charging 12 volt batteries wired in parallel requires a 12 volt battery charger. Take two batteries and connect them in parallel. Two 12 volt batteries wired in parallel continue to produce 12 volts but the capacity doubles. But what happens if you wire batteries of different voltages and amp hour capacities together in parallel.
If the input rating on the inverter no matter what the output wattage says 12 volts you must only connect two batteries in parallel. Connecting them in series will seriously damage the inverter. Attach the positive terminals together and the negative terminals together. Make a parallel connection for the two 12 volt batteries. Finally take a jumper wire and bridge the positive terminal of one parallel connection to the negative terminal of the second parallel battery pair. Four 12 volt 2000 mah wired in parallel can provide 12 volt 8000 mah 2000 mah x 4.
Two 12 volt batteries in series give you 24 volts. The parallel connection of two identical batteries allows to get twice the capacity of the individual batteries keeping the same rated voltage. Connecting batteries of different voltages in parallel. Connect the two positive terminals on both batteries together. Batteries may be wired in parallel or in series. This is the big no go area.
Two 12 volt batteries in parallel give you 12 volts.
