Relation between battery cell capacity & internal resistance
I''m trying to design a large battery pack, that should provide a given amount of power, with a reasonable amount of heat dissipations. To do so, I have three degrees of freedom: indidividual cell internal resistance increases when capacity decreases these parameters
Understanding the Role of Cell Balancing in Battery Packs
Internal impedance changes are another reason for cell unbalance mostly during the discharge cycle and might lead to resistance imbalance. The unbalance in the battery pack can lead to severe consequences and its composition is as shown in Figure 2. Figure 2. Composition of a battery pack. Image courtesy of UFO Battery.
All Things You Need to Know about Internal Resistance of Lithium Battery
Dividing this difference by the test current is considered to be the DC internal resistance of the battery.

Battery Internal Resistance
Battery internal resistance is the resistance that exists within a battery due to the flow of current through its electrolyte and other internal components. A battery internal resistance chart can be used to monitor the internal resistance of a battery and identify any potential issues before they become a problem.
