I personally find the FMA Supernova (sold under a few names,
often for less) best suited to field fast charging of motor
packs. It can fast charge 1600 mAh packs in about 20 minutes
at the 3C rate (for bigger packs try a Novak Millennium).
I don't like it's 500 mA discharge rate for cycling receiver
packs. This just seems a bit high to me, as I like to discharge
at roughly the same rate as actual use (250 mA is typical for me).
The battery experts say the high rate is not a problem for small
packs, though it may cause the reported capacity to be a little
lower than when in actual use.
All in all though, the FMA Supernova it a great product.
