I think the original battery claims are moot at this point. No one shpuld be bothering to defend them or considering them real anymore, and I dont think anyone is. Good to see that even with the full deep draw machine can do that many chambers, since that's the most taxing on the battery when you draw enough to kill a bowl on one hit (like they seemed to say in one of the questions posted here).
They should run that same test, but sticking to one temp, to get a real idea of battey life, and run a whole batterys worth for each of the temps like 170c-175c-180c-185c-190c-195c-200c-205c-210c, so then we'd get a better idea of real world useage (though many of us will sip on it more, but this will be a scientific way to show us battery life at least). This was the avb video, they still need a battery video.
Since it seems like those first two settings are extremely low temps, just like decarbing the herb it seems? More for other herbs perhaps, and why in first video she got no real clouds until mid temp, which is still really low actually... Most real useage would span the tick marks 3 to 5, 338F to 410F, I imagine. Though I know i will certainly be trying out the effects on the lower temps too, could be really fun if they have heady effects even that low, and really good for battery life.
