Li balance charger with individual cell capacity

Is there any balance charger that displays individual cell capacity, either directly or via the PC software?

This would make it much easier to test recycled 18650 cells, 3 to 5 at a time, while currently I can only have one per charger channel.

Not indivual cell capacity but instead indivual cell voltage which if they are the same when discharged and charged capacity will be the same.

I found differences in capacity up to 30% on cells taken out from a laptop pack.

When discharged low capacity cells will reach lower voltages first.

Take some of the30% lower capacity ones and place them in series wth some of the better one, do a balanced charge then discharge them and monitorthe indivau cell votlages and the lower cpaity ones will run out juice firstand when charged will reach set charge to voltage first .


See third attachment here note red line cell #3 is th low capacty one
