I've held out on this thread. I firmly believe the problems are caused by the enormous variation rates of self discharge on modern cells. I think equalising before charge is vital and with this your chances of problems are enormously reduced.
I always equalise cells before use on their first charge of the day. If I'm using a pack of cells twice, I most likely won't bother for the 2nd charge though.
For racers this is fine, but it's the kids with stick packs etc I get most worried for.
