Voltage sag under load is normal due to internal resistance. Check C-rate requirements - most Li-ion cells perform best under 1C discharge rate. Internal resistance is a natural property of the battery cell that slows down the flow of electric current. The reason for this is that with a large battery bank like this, it becomes tricky to create a. . The internal resistance of a lithium battery pack is influenced by several factors, including the battery chemistry, temperature, state of charge (SOC), and the physical design of the battery.

The resistance of a battery pack depends on the internal resistance of each cell and also on the configuration of the battery cells (series or parallel). The overall performance of a battery pack depends on balancing the internal resistances of all its cells.
High internal resistance in a battery pack can significantly impact its efficiency. As electric current flows through the battery during charging and discharging, energy is lost primarily as heat, a direct consequence of the internal resistance.
If each cell has the same resistance of R cell = 60 mΩ, the internal resistance of the battery pack will be the sum of battery cells resistances, which is equal with the product between the number of battery cells in series N s and the resistance of the cells in series R cell. R pack = N s · R cell = 3 · 0.06 = 180 mΩ
A key parameter to calculate and then measure is the battery pack internal resistance. This is the DC internal resistance (DCIR) and would be quoted against temperature, state of charge, state of health and charge/discharge time. Symbolically we can show a cell with the internal resistance as a resistor in series.
