Yep, that's all I can come up with other than the I-Charger 208B (20A, 8S).
No manufacturer (that does RC anyway) has yet produced a 5C capable charger that I'm aware of.
To be fair, 5C isn't that much of an improvement on 4C (if 1C takes 1 hr from flat, 2C takes 30 minutes, 3C takes 20 minutes, 4C takes 15 minutes, 5C takes 12 minutes). It's only 3 minutes improvement, you're hardly going to notice.
Either of the chargers we've suggested can charge at 4C, so still pretty damn quick.
