Ok, the mfr sent me a build with fixed cycle testing,
I set one up to start with:
3A charge to 3.65V (taper to 2A)
2A charge to 3.9V (taper to 1.2A)
1.2A charge to 4.15V with 200mA cut.
7A discharge to 2.75V (~21 minutes, very heavy load)
repeat for 450 cycles.
should be good for ~14 cycles per day...
I used the stepped charging to fast charge the cell without damaging it. Gleaned from Tesla. CC/CV charging is bad for Lithium Ion in general... plan to start a thread bout that in the future.
Will also setup a similar cycle test on a Model S cell. Need to calibrate the other 7 channels first.
