Cells in Parallel
Internal ResistanceResistance in Joints and BusbarsEqual CoolingFinite Element Version of A Large CellInternal Current FlowCell Level FusingA battery cell is not a perfect current source as it also has an internal resistance. The internal resistance of new cells can also vary and hence when connected in parallel the cells with a lower internal resistance will deliver more than their fair share of the current. This means these cells will run hotter based on I2R heating See more on batterydesign.netWiley Online Library
