You may want to reconsider..mechanical switches can develop "bounce"...I used a similar type ones and half of them started unintentionally locking the mod...a real pita after it happened to you several times a day

I got the impression it was fairly continuous or at least a lot heavier then typical vaping use (i.e. 1/2 the battery in 30 mins)...Im thinking the on board battery data is as a course of typical use, not really designed to work as continuous (more less) drain analyzer..perhaps something like west mountain radio's computerized battery analyzer (or similar) might work better if you need to test batteries quickly

I wouldnt expect the board would be able to handle this type of continuous loading abuse....my computer battery analyzer has a big ole heatsink and fan for a reason ...

Ive had pretty decent success with the Aoyue 9378 station...used it on about 60 dna mods so far the auto shut down and motion sensing auto on is a nice touch...fairly decent thermal mass with ceramic, comes with nice supply of various tips and a spare replacement heater nice middle of the road setup...not industrial but pretty good bang for the buck IMO and Id put it up against the Hakko in the same price range with a bunch more features and extras
