Are Zippy Lipos safe with a Castle MMM Speedy?

Ok, what about the balancer tolerance? Does it balance the cell you measured as 0.01v difference? I know my blinky doesn't. The most accurate balancer I have is the LBA10 (it actually seems almost too sensitive).

For your level of "anal" (), I wonder if the FMA charger would be a better choice. Has a high power limit, balance charges, and also measures cell condition/quality. To do that last item, it must be quite accurate.
