Fast discharging at 10 amps down to 0.9v/cell doesn't actually bring the nominal voltage that low. A cells voltage may be 0.9v at 10 amps, but at 2 amps its closer to 1.1v. I have had no problems or unbalanced packs using this method for several months now on both matched and unmatched/very low packs. In the UK this is the most common method of looking after cells when racing I have observed, the biggest variation is if you equalise after fast discharge, or just before recharging, I do it just before recharging.

Contrary to what a lot of people say, you can take NIMH's below 0.5v/cell or even dead short them, if you start doing it while they're new, otherwise they don't take to it well. Doing this shortens their life and runtime but does give a noticable increase in punch.

If the cells were that unbalanced that one cell can be 0.9v and another 0.2v causing damage the packs not likely to be any good anyway. I personally haven't seen this much variance in cells even on packs that have been abused on a pulse charger for over a year.
