Yeah, they are for my Kyosho Mini Inferno.
The charger I have now is the Dynamite Prophet Plus (4-7 cells). I've been charging my 8-cell packs on it, because I never noticed it was rated for only 4-7 cells. I tried charging half a pack at a time yesterday and got 3-4 minutes more runtime, and a bunch more top end, proving it really can't charge 8 cells.
I'll take a look at the Ice, thanks!
