having trouble properly discharging, getting capacity
#11
Yes, it appears both dischargers drop sizable voltage under just about any load (100 mA to 1000 mA) towards the end of discharging and then rebounds after a couple of minutes to at least 3.6 V or higher. From all of your input I'm assuming this is not suppose to happen (sizable voltage drop towards after discharging for a while) even though these cells are used/harvested and only have a 2C/5600 mA/5.6 A rated discharge current? If this is normal, then what can I expect if I stubbornly used 140 of these anyway for a 14s10p battery pack for a 52 V/30 A (1560 W) e-bike motor?

wow, if they are swinging that much even under 100mA load, I don't think it'd be worth it. No cell should swing that hard when under light load. Especially at those voltages. Maybe if they were around 2.2V it would, but not jump from 3.6V
