The HL charger only does 50w max out. A 5s 5000mah pack needs
( watts=v*a) 100 watts to charge in one hour assuming a 1c charge rate. If you use the hobby lobby charger you will be at its max output rate in order to charge a 1c battery in two hours...not sure I would go with this ,although for the money you might try it. I would spend the money on the single output hyperion and the hobby lobby 16amp PS. I use the hobby lobby 16a supply at the track and it works well, at home I use a 25 amp supply with my hyperion duo and can run 180watts per side.
