quick discharging question

[Sammus]

you say 0.09V each cell. 7 cells. Thats 7 times 0.09 = 0.63V. I have a niggling feeling you actually meant 0.9V though, which is 6.3V for the pack.

If you did actually mean 0.09V (I think some people like to take their nimh cells right down near zero). Do them individual, because the slightest bit of unbalance in your pack will wreck one of the cells if you try and take it below 0V.
