Maximum Cell Discharge Capability
We can also calculate the maximum current we can draw taking the cell down to the minimum voltage: 2.5V = 3.7V – I x 0.025Ω. Rearranging this we can calculate the current: I = (3.7V – 2.5V) / 0.025Ω = 48A. These numbers are quite typical of a 5Ah NMC cell. Peak discharge is around 10C.
