When the internal resistance of a battery cell is high, it can lead to a decrease in the overall capacity of the battery pack, as well as a decrease in the efficiency of the pack. This is because the internal resistance of a battery cell creates a voltage drop within the cell, which can cause the cell to heat up and decrease in performance.

12V Lithium Battery Voltage Chart Generally, battery voltage charts represent the relationship between two crucial factors — a battery''s SoC (state of charge) and the voltage at which the battery runs. The below table illustrates the 12V lithium-ion battery voltage chart (also known as 12 volt battery voltage chart).
The power output of the battery pack is equal to: P pack = I pack · U pack = 43.4 W The power loss of the battery pack is calculated as: P loss = R pack · I pack 2 = 0.09 · 4 2 = 1.44 W Based on the power losses and power output, we can calculate the as: η
