Customer ServiceInternal resistance is a natural property of the battery cell that slows down the flow of electric current. It’s made up of the resistance found in the electrolyte, electrodes, and connections inside the cell. In single battery cells, this resistance decides how much energy is lost as heat when the battery charges and discharges.
The internal resistance of the battery pack is made up of the cells, busbars, busbar joints, fuses, contactors, current shunt and connectors. As the cells are connected in parallel and series you need to take this into account when calculating the total resistance.

What is the average internal resistance of a battery? The average internal resistance of a battery varies depending on the type and size of the battery.
The greater the internal resistance, the more significant the voltage drop. To illustrate this, consider a simple experiment with a AA cell. When connected to a 4 Ω resistor, the voltage across the battery terminals might drop from its VOC of 1.5V to around 1.45V. This drop is due to the battery’s internal resistance.
