The parallel connection of two identical batteries allows to get twice the capacity of the individual batteries keeping the same rated voltage. Therefore you need 4 x 100 ah 400 ah in parallel provided that the voltage required is 12v.

4 12v batteries in parallel. The system is comprised of four 12 volt batteries wired in parallel a charge controller and an inverter. 4 x 12v 120ah batteries can be wired in series parallel to give you 24v with 240ah capacity. They can have different capacities on account of size or age but the same chemistry eg. Lets suppose you have 3 different 12v batteries wired in parallel to supply 12v power to your rv. There are two types of circuit parallel and series. Charging 12 volt batteries wired in parallel requires a 12 volt battery charger.
A series circuit is where all the cells are in line ie to. 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. But what happens if you wire batteries of different voltages and amp hour capacities together in parallel. Will a s4 100ah bms be a correct match with my battery pack described above or is another s. Two 6 volt 45 ah batteries wired in parallel are capable of providing 6 volt 9 amp hours 45 ah 45 ah. Four 12 volt 2000 mah wired in parallel can provide 12 volt 8000 mah 2000 mah x 4.
Purchased 8 180ah calb 3270 3273 batteries. All flooded lead acid or all agm. The 2nd config is 4 parallel connections at each battery end also 2 rows of 4 batteries each row connected in series and of course the 3rd image is 3 parallel connections with 3 batteries connected across their and terminals and a single row of serial connected batteries to make 48v. Connecting batteries in 4 groups of 2 series then connecting those groups in parallel for a 12v battery for our rv. If you have 4 x 12v batterys and want to connect them together then you want parallel. Well in series circuit the terminal battery voltage sum up then 2 x 12v cat 24v but the ampere rating will be 200 ah only.
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. Im confused which batteries to connect to the charge controller and the inverter. Seems most diagrams dont include the connection points for both the charging and discharging sources. 4 x 12v in series would give you an output of 48v. 4 x 6v 120ah batteries wired in seriesparallel will give you 12v at 240ah.
