50watt charger is good for about ~2-2.5amps with a 5s lipo, I know that is true from owning a Bantam BC6- very similar to the Hyperion 606i in spec.

Depends really, for a straight forward charger you can get very cheap ones that'll charge your pack in around 2 hours, or if you have the budget you can pickup a more powerful unit and do 1c charge rates, or upto 5c if you have the right lipos.

Im guessing you have hobbycity ones though, so 1c = 1 hour to be safe.
