As m number of series connected in parallel equivalent internal resistance of that series and parallel battery is nrm. You can connect your load to one of the batteries and it will drain both equally.

Battery in parallel formula. Set 1 b 1 b 3 b 5 series. 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. One point to remember when you fit batteries in parallel always use the same voltage capacity make and model of battery. Two 6 volt 45 ah batteries wired in parallel are capable of providing 6 volt 9 amp hours 45 ah 45 ah. Negative to negative and positive to positive. Similarly if r 1 r 2 r 3 r n are the internal resistances of individual cells then the internal resistance of the battery will be equal to the sum of the internal resistance of the individual cells ie.
Video presentation about series parallel batteries. For example alternatively if your batteries are in series the opposite is true. Laptop batteries commonly have four 36v li ion cells in series to achieve a nominal voltage 144v and two in parallel to boost the capacity from 2400mah to 4800mah. Cells are in parallel combination if the current is divided among various cells. 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. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage.
Two parallel sets of three batteries are connected in series. R r 1 r 2 r 3 r n. The positive end of one battery will connect to the negative end of the other battery. And then the pair of these batteries are connected in parallel ie. Such a configuration is called 4s2p meaning four cells in series and two in parallel. The equivalent resistance of the series is nr.
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. If the mod youre using is in a parallel configuration both the positive and negative ends of each battery are connected together or touching. Cells in parallel connection. As n numbers of cells are connected in each series the emf of each series as well as the battery will be ne. I dont fully understand your question about a formula but when you add batteries in parallel the voltage remains the same it is the capacity that increases.
