I don't believe either of those chargers can full-charge your batteries @10A. The Hyperion for sure is limited to 5A/50W, the TP looks to be limited to 10A/80W. You need 8.4V*10A = 84W total to fully charge 5Ah batteries at 2C, so you're right at the limit of what the TP charger can do.
That's the disadvantage to AC/DC chargers... most are limited to 80W or less total output.
