Just for posterity, I'll copy out a document I made for myself when I was looking for certain ego batt sizes. These are approximate since different sites seem to not have the numbers the same
I red colored the ones you may be interested in:

As you can see the red bolded ones, the micro is not VV but the Spinner 450 is. The Ego C Upgrade battery is also less than 3", but it is also not VV, well, not totally.....it has 2 settings, one for regulated and one for unregulated, vicki at cignot has them.
