josh Posted October 7, 2015 Author Report Share Posted October 7, 2015 So a 0.05 ohm build (for Ni200 TC) at 125w would have 50amp draw, the 0.05 ohm build at 35w would have a 25amp draw...Am I right in saying that the DNA200 has an onboard 25amp fuse which could blow if you go over it?Also what happens if you go over the amp limit on a 3s lipo?As my math suggests bad news I havn't been brave enough to try it but I know people who have but would like to see what Evolv say about the fuse and everyone else about the lipo?Thanks in advanced, Link to comment Share on other sites More sharing options...
Brandon Posted October 7, 2015 Report Share Posted October 7, 2015 That would be absolutely true IF the DNA 200 were a mech mod but it isn't. The DNA 200 is a converter which steps down voltage and steps up current and can output the needed 50 amps while only requiring a maximum of 23 amps from the battery to do it. Well within the safe range of most 3s Lipo's. Link to comment Share on other sites More sharing options...
josh Posted October 7, 2015 Author Report Share Posted October 7, 2015 Hi Brandon, Do you work for Evolv out of interest?So essentially you can build the 0.02ohm lowest NI coil run it at 200w on a 30amp battery and it won't cause any issues to fuse OR battery?

VapingBad Posted October 7, 2015 Report Share Posted October 7, 2015 As with all regulated devices you need to think in Watts each side of the converter and allow for electrical efficiency. The board is 97% efficient so when it provides 200W to the coil it needs 207W from the battery, the amps will be highest when the battery is lowest (9V) so the current needed from the battery at 9V to supply 207W is 207W/9V = 23A (P/V). It doesn't matter what the coil ohms. Link to comment Share on other sites More sharing options...
Brandon Posted October 7, 2015 Report Share Posted October 7, 2015 Yes, I work at Evolv and yes you are correct. Although, you're unlikely to hit 200W due to the boards 50 amp output limit. Link to comment Share on other sites More sharing options...
Tomr1088 Posted October 7, 2015 Report Share Posted October 7, 2015 Yup. I built to .03 and if I had it set to anything over 80 ish watts it would display check atomizer. Or short Link to comment Share on other sites More sharing options...
