If you're still onlyinerested in 2S, then the Hyperion has enough power running on AC to charge them. The Hyperion specs on AC are -

100V~240V AC (20A, 90W max charge).

Your 2S lipo require 42watts if I remember correctly that they're 5000mah 2S lipos. If they are 2C charge rated, you'd be able to charge them at 2C and cut charging time.

The Team Orion would obviously work too, it has to have a separate power supply and once that cost is added to th epicture, these are not that diff proce wise. If you got the Protek Pro 20 power supply that'd add $65 and make this option a wash price wise compared to the Hyperion.
