Awesome. So I've been reading up on them and DNA200 generally runs 11.1v with a 9.6v cut off (3.2 per cell). If I am following that correctly, then that means that I would get the Low battery message for a given wattage if the voltage dropped below 3.2. So for the Triade which is 3 batteries in series, the amp pull for a given wattage before cutoff would be as follows: (assuming a 10% circuit drain, which is high but w/e) 50w (50/9.6)*1.1 = ~5.72 amps 100w (100/9.6)*1.1 = ~11.45 amps 150w (150/9.6)*1.1 = ~17.18 amps 180w (180/9.6)*1.1 = ~20.6 amps 200w (200/9.6)*1.1 = ~22.9 amps If I'm not completely off base, then the LG HG2's would be good for up to around 180w based on the cut off, but shouldn't be used at 200w. The Samsung 25R5's are also 20 amp and would be good for about the same, but are slightly lower capacity. The Sony VTC4's are closer to 23amp according to Mooch, so if I wanted to get the full 200w, then I would need to get these or another similarly amp rated battery. (Also 23 amps is the max on a DNA200 so anything higher is a waste anyway) Since I am currently using the SmokTech TFV8 and usually vape within the 120-150w range, any of these will work and the HG2's might be best because of the additional capacity. Sorry for the long post, just trying to make sure I wrapped by head around this correctly before I order the new batteries.
