By that formula, I get 4.25 hours for the wall charger. Not bad, actually, but not by any means swift.
I think I confused the initial charge time with what's recommended for the 1/6 M5 Stuart (12-14 hrs).

How long does it take to charge your packs at 1 to 1.5 amps, swathdiver?
Just wanting to know what kind of time savings I'd get with a serious charger such as yours.
