Chargers that can charge at more than 10A / 2C? What do you use?

[gtxracer]

I currently run a 1210i with dual LBA10s at 10A when charging two 2s Neu XP 5000 packs. They can be charged at up to 5C, but 10A is only 2C, so what charging options do I have?

In the future, I want to run the g3 hyperion packs too, so it would be nice to stay in the Hyperion family of chargers if possible. I know the 615i duo can charge at up to 15A each, but that's not 5C either.

So what does everyone else use?
