Best damn balance charger I ever had

[mistercrash]

The BC168 is adjustable from 1.5V per cell to 4.2V per cell. It won't go over 4.2V. But it does get the cells up to the voltage you set it at.

From what I understand, on most chargers like the Cellpro 10, the balance leads are plugged in just to monitor the cells and to slowly discharge the high ones while the low ones catch up during a sometimes long balance cycle.

I'm thinking that your GT Power GT8 did actually charge your cells to 4.2V but they simply got down to 4.18V quickly after the charge is done. Cells that are a bit tired because of repeated over charge might do that.
