Are Zippy Lipos safe with a Castle MMM Speedy?

I think the software limitation is a good idea. I would hazard to guess that 99% of the people that run these things dont have a clue about what we are talking about. They just want a reliable esc that will work with whatever they throw at it. Most people also cant afford the high end batteries to get the most out of these setups anyway and they could fall into a trap by using the cheaper batteries and gearing up. I have zippies, truerc batteries and dont have any problems with my 2 MMM. Its like patrick said, its running the system within its means. I dont go out and gear for extreme speeds with my batteries so I dont have any trouble. The typical person however has no clue that any of this could happen. The fact that C ratings also arent standardized just makes it even more difficult even for those of us that know what are doing.
