Am looking for a new charger, and have a feeling my expectations are too high!! Anyway, thought if I posted my wishlist some of you guys could point me in the direction of the best options, please! What I'm looking for, to charge my 2s lipo packs, is:

Mains and 12v input
Fast discharge rate for storage (eg can discharge at more than 1A)
ACCURACY - a good reputation for balancing/not over charging

Nice to have's:
Multi inputs (eg charge more than one pack at a time)
More than 50w (ability to charge 2s at 7-8A)
Ability to charge nimh/life as well

What would anyone recommend? Are fusion chargers any good?
