I just checked the page for a set of zippy lipos I just received and it says the same thing...BUT on the back of the actual pack it says never to charge above 1C. So i'd do it at your own risk.
Yea, I noticed this as well...the thing is, though, it may be safe to charge them at 2C, but it is not recommended so Zippy left the recommended 1C charge-rate on the packs.
