Okay, finally putting together the 14 packs of 160 cells each for my powerwall build--got the connecting wires (28 AWG tinned copper) for the negative side all welded and soldered in and just got the 32 AWG tinned copper wire for my positive side fuses.
As I make these packs, I would like to capacity test them before final assembly into the battery. I have an icharger X8 and a variable 30V 10A bench top power supply--so I think charging it will not be problem, just a very, very long time; however, I do not have a battery that I can regeneratively discharge the pack into. Since it will only be 3.7 V nominal, I don't have a inverter or anything I can run to discharge the pack into. I know the icharger has the ability to discharge without regenerative, but is that realistic? I haven't seen anyone use that so I don't know how well it can discharge such a large pack.
Do you guys test your packs before assembly into the large battery?? If so, how do you do it?
Thanks
