The parallel connection of two identical batteries allows to get twice the capacity of the individual batteries keeping the same rated voltage. But what happens if you wire batteries of different voltages and amp hour capacities together in parallel.

12 volt batteries in parallel diagram. Two 12 volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12 volt battery. The process is simple but as the capacity of the batteries increases depending on the number of batteries wired in parallel it can take twice. Four 12 volt 2000 mah wired in parallel can provide 12 volt 8000 mah 2000 mah x 4. Once you have the batteries wired properly in parallel you will need to connect the 12 volt power wire from the trailer 7 way connector to the positive wire on the first battery. Two 12 volt batteries in series give you 24 volts. If charger is.
Make sure that your power inverter could afford charging several parallel connecting batteries at a time. Remember electricity flows through a parallel connection just the same as it does in a single battery. In the diagram above we have a battery bank that produces 12 volts and has 20 amp hours. Connecting them in series will seriously damage the inverter. Charging 12 volt batteries wired in parallel requires a 12 volt battery charger. Two 12 volt batteries in parallel give you 12 volts.
If you own a single battery inverter you can connect more batteries in parallel as overall voltage of pack will remain the same while capacity multiplies. Dont get lost now. 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. Two 6 volt 45 ah batteries wired in parallel are capable of providing 6 volt 9 amp hours 45 ah 45 ah. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage. 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.
If you have two sets of batteries already connected in parallel you can join them together to form a series. Connect multiple batteries in parallel with your power inverter solar hybrid inverter or ups to increase its backup. This connection will help maintain the batteries when the vehicle is running but will not charge them sufficiently from a discharged state. If the input rating on the inverter no matter what the output wattage says 12 volts you must only connect two batteries in parallel. Can two 12 volt batteries connected in parallel be charged through a switch using a noco charger should 12 volt circuit of trailer 7 way charge dead trailer battery can 12 volt accessory circuit on a 7 way trailer connector be used to maintain a deep cycle battery.
