Just my opinion/thoughts. So you take a 900 mah 3s lipo and re-wire it parallel, now it's a 2700 mah lipo. Sounds good, right? Well it's still just 10 watt hours. Given those numbers I see no advantage to building a DNA75 using a lipo, I would just spend a few bucks more and use the 200 board. I do see a market for the 75 with interchangeable 18650/26650 though as most folks vape at way less than 75 watts. Again just my way of looking at it.
