Thanks for studying my case and your usefull replies!
@truus: yep, de balancing staat op ALWAYS. I guess it's balancing from the beginning, probably the balance current (300mA
according to nlc) is proabably to small to be notice on the graph.
@nlc: Very clear explanation, feel stupid not to have realized earlier myself...the drop @3,65V is off-couse a voltage drop
due to current reduction...stupid me.
I can see Cell 9 is earlier full indeed, possibly it's one if the 2 extra cells I had ordered in a second batch (from evassemble.com whereas first 16s comes from bmsbattery) as backup cells, but ended up adding them to the setup as it was rock steady at 16S....so ironically the 2 spare cells that were ment to keep the pack in good condition no thew make it less balanced
...anyway when reading truusjes values I guess my packs are still not running for the title of most unbalanced packs on the forum.
Will try to do some discharge logs with celllogs and research on the single cell top off technique. (thanks Scott - also packs are very new indeed and were disconnected from controller for charging, will research on the single cell top off technique...but if the diagnosis of less capacity is correct (seems to be supported by the latest charging graph) not sure this is a durable solution).
In an attempt to end the charging process sooner I switched to FAST setting for balancing (stops charging at ICC/5) and charging to just 3,4V. Interesting to see cell 5 (probably the best cell)reaching 3,4V first because of better state of charge at the start and again cell 9 reaching "real" saturation (due to full charge) 3,4 V probably earlier in a second stage. But now a new mystery (at least to me appeared)...What can be the origin of the power blackout (but not fully black...) spikes at the beginning of the graph?
Again, thanks to all, reassured all's pretty normal, can read the curves better already,
