That is probably not possible. The idle voltage or resting voltage is the lowest after a low current discharge. To get back to this, very low, voltage you have to discharge the cells far beyond the reasonable threshold.
Example: 14S battery, 42.0V empty, 51.8V nominal, 58.8V fully charged
Now imagine the battery comes fresh off the charger. Since you have new cells lets assume they keep their end of charge voltage of 4.2V so the battery voltage is still 58.8V. You have 36 of the MG1 in parallel so the maximum continuous discharge for your battery is 360A and the total capacity is 102.6Ah.
0.2C: 20.52A
0.25C: 25.65A
1C: 102.6A
2C: 205.2A
5C: 513.0A
One thing becomes obvious immediately, your battery can't to a 5C discharge. 2C is a normal to high load, 1C is a normal load, 0.2C is a low load.
Now you put a load of 20.52A on the battery. That's 570mA per cell. Their voltage will now drop, because of the load, from 4.20V to 4.10V immediately. They will run like this until the cutoff voltage is reached and the cells will bounce back to their idle voltage. Let's say we cut off a 3.00V and they return to their idle voltage of 3.10V.
If you would put a high load of 205.2A on the battery instead then we have 5.7A per cell. Their voltage will drop not to 4.1V but 3.9V instead and run through the discharge from there on. They will hit the cutoff voltage sooner and then get back to 3.3V idle.
Any load works like an offset on the cell voltage. And it is not necessarily the same on the high end and on the low end, this is just an example. To reach the same idle voltage after a low current discharge and a high current discharge you would have to discharge further on the high current discharge because the offset is bigger. But this is not possible because the offset is bigger. It is a bit of a causality dilemma like chicken or egg. This is the reason why cells don't have a capacity as such, but a capacity at a given discharge current. The low voltage cutoff is always the same but the offset is bigger on the bigger loads, so the capacity is lower on bigger loads than on small ones.
