EDIT: i'm wondering if you're right Neil....my weak pack is doing some crazy stuff. i keep getting "voltage too high" on my hyperion charger with readings of 4.86 3.85 and 4.98...i put the cell spy on it immediately and it's 4.19 4.19 and 4.20. i wonder if the spy is getting some false readings too.
it makes me think you might have hit the nail on the head
i'm definately going to be doing alot of testing tomorrow....and getting some contact cleaner.
