Due to different manufacturing processes the exact voltages of batteries from different producers can vary slightly. For example for the above circuit the measured voltage across battery 1 is 48v and battery 2 is 36v.

Batteries in parallel voltage calculation. Negating 48v 36v12v gives us battery 1 voltage. Parallel connection attains higher capacity by adding up the total ampere hour ah. This means a 15 volt battery from brand x could actually be 16 volts while a 15 volt battery from brand y could be 155 volts. When in parallel we add the amperage and average the volts eg. One point to remember when you fit batteries in parallel always use the same voltage ca. Time of charge or discharge in minutes run time min calculation of energy stored current and voltage for a set of batteries in series and parallel number of batteries in a serie elements number of series in parallel series.
Just input the number of batteries youre using whether theyre in series or parallel the current rating cdr capacity mah and the voltage of your individual batteries. 1800 mah 12 v are connected in parallel the output voltage of parallel circuit is remain 12 v butt current capacity becomes 3600 mah. When two identical batteries are connected in parallel it will double the current capacity and the output voltage remains the same as a single battery. 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. The voltage in this circuit is actually identical for all 3 branches and it is likewise identical to the voltage of the supply which can be expressed asvs v1 v2 v3. When taking two 6 volt 100 amp hour batteries in series it becomes 100 amps at 12 volts.
Second diagram consists of parallel circuit involving 3 resistors and a voltage supply. Some packs may consist of a combination of series and parallel connections. When in parallel it becomes 200 amps at 6 volts. Hit the calculate button and our series vs parallel battery calculator will give you the total combined voltage cdr and capacity of your batteries. 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. For example suppose two batteries of same rating ie.
The technique is to measure the voltage across high potential battery first than against the lower ones and negating the subsequent batteries voltage from the one at higher potential.
