Are Zippy Lipos safe with a Castle MMM Speedy?

To add to the logic - most people report increased power in the otherwise identical setup when switching to the MMM controller(myself included). Perhaps the trade-off is that this more pronounced and available flow of power goes both ways, making the controller more prone to failure due to "issues" more commonly found in lower quality batteries. I am not the manufacturer and I did not join the discussion to offer anything other than my thoughts on batteries causing esc failure - using better batteries will yield better results in all cases.
