Fourth stick done, same results as first three. SB is telling me 7310 on discharge also, perhaps I scored some super good sticks!? Now set up my fifth stick before work, 4 cycle, changed delta to 6. At this rate I can do two sticks in 24 hrs at 4 cycles each. Exciting to get out of the learning stage and actually start cycling these babies up. Time will tell how they hold their juice.
hmm... I wonder what could be wrong with the SB that would make it miss the cutoff parameters and keep charging [and discharging] to the presumed fallback limits? For example, if you were using the temp sensor only then it'd be the temp sensor...

Reason: add "and discharging"
OK I have been getting through this pack and have completed cycles on 14 sticks. I have found 2 sticks considerably weak (Noted in red on spreadsheet) and will be replacing those.
I have been getting the max MAH out of the other 12 sticks charge AND discharge. The other day I received a PM from a member saying why don't I up the MAH setting in SB to 7100 to see what these sticks really have for capacity. Curiosity got the best of me, and I have completed one stick yesterday (Now down to 3 cycles) and one going this morning at MAH rating set to 7000MAH. I now am seeing results in the upper 7000s charge and discharge, on completed stick second stick looking strong not complete yet.
Can this be right? Am I risking anything by upping the MAH setting above 6500? How high MAH will these sticks go!? It seems the numbers I am getting are a cutoff of SB from initial setting once again (7310 most cycles at 6500MAH SB setting), and perhaps there is more capacity to have?
That just doesn't seem right to me. Have you checked to see if the sticks are getting hot? Have you observed the readout when approaching the termination parameters upon both charge and discharge, watching for more or less normal values (for example, voltage seemingly peaking upon charge, voltage hitting the cutoff upon discharge)? I'd be a little worried that the charger isn't working properly and overcharging and over discharging the sticks... They're all orange plastic wrapped, right?

Eq1,
You're making me feel better about building my own charge/discharge system!.....

Nothing is getting too hot, I have plenty of air moving over everything with external fan. Battery cutoff is set to 130F and has not gotten near that. Yes I have watched the readout through several cycles, the charger seems to be doing its job just as it should. I have compared voltage with SB and handheld voltage tester and they are similar. 17 of the 20 sticks are original to the pack.
