$begingroup$ @MarcusMüller This is a trickier question than it looks and the cited answer addresses mAh ratings and largely NOT C ratings. For identical cells. If both have eg 25C capacity then in parallel they are 50C rated compared to ONE CELL. BUT if each is 300 mAh then in parallel capacity is 600 mAh and C rating is 25 x 600 mAh Ie you need to specify if the …
I have a circuit of a battery pack of 4 18650 and a 4S BMS. See the picture below.

There are 3 methods for connecting batteries and constructing a battery bank: Series, Parallel, and Series/Parallel Combined. We will describe each method briefly using illustrations to give you a clear concept.
Batteries in series combination are connected end-to-end, so that the positive terminal of one battery is connected to the negative terminal of the next battery. The voltage of the batteries is added together, so if two 12-volts batteries are connected in series, the total voltage would be 24 volts. However, the current remains the same as that of a single battery.

$begingroup$ So in other words, as the cell in the parallel bank approaches total charge depletion, it would not affect the bank V when it is 100% depleted,but it would eventually cause that bank to be depleted sooner than the other banks in the battery. When the charge of that bank is depleted, it will output less V & cause the battery to have a lower V …
