Yes, they do work, but the higher voltage of the V4l batts tends to distort the flavor of the
juice. My daughter uses the V4l batts with the Bloog cartos.
What she does is bottom fill(she drips into the battery end of the carto and then cleans the threads) the cartos to top them off more often so they do not burn.
I find that the bloog cartos are by far the best. Easy draw and lotsa vapor. If the cartos are used with the bloog
batteries that flavor is awesome.
