Are Zippy Lipos safe with a Castle MMM Speedy?

I thought the rhinos were enerland rejects or something because the cells are the same size and mah as a lot of PQs. The zippy cells have difference dimensions to any of the enerlands, so I'm pretty sure they come from another factory. That and even hobbycity tell us their cells come from a chinese factory, and enerland is korean as we all know.
