I 'm using a Velocity V2 base SKU 4656900 with billow V2 nano glass SKU 3597100 and it fits perfectly.
Just remove that ultra tiny grub screw INSIDE of the positive pin of the base and u're ready for squonking.

Good to know. The base of the Velocity V2 that I have (SKU 4491602) is too wide for Billow V2 Nano glass but my Velocity V1 base fits well. I figured all the Velocity V2's had the same size base. Inconsistent clones...
