A high discharge event caused during short a short circuit could cause the voltage to dip to unsustaiable levels. Running a battery over the specified maximum discharge rate could damage the battery and should be avoided in most applications. Figure 4.
The cutoff voltage should also be lowered when discharging at very cold temperatures, as the battery voltage drops and the internal battery resistance rises. Table 4 shows typical end-of-discharge voltages of various battery chemistries. The lower end-of-discharge voltage on a high load compensates for the greater losses.
When removing the load after discharge, the voltage of a healthy battery gradually recovers and rises towards the nominal voltage. Differences in the affinity of metals in the electrodes produce this voltage potential even when the battery is empty. A parasitic load or high self-discharge prevents voltage recovery.
Hence the voltage of the cell under a 10A load will be 3.45V. We can also calculate the maximum current we can draw taking the cell down to the minimum voltage: Rearranging this we can calculate the current: These numbers are quite typical of a 5Ah NMC cell. Peak discharge is around 10C.

A major concern in battery applications is the minimum allowed discharge voltage of a battery. If the battery is drained under this specified voltage, it can lead to permanent damage.
