KonzKamz Posted October 11, 2016 Author Report Share Posted October 11, 2016 Hi everyone,I'm newbie of DNA chip. My Hcigar DNA75 NANO case is hot quickly when i smoke, is it normal? (0.3 ohm/55W-65W/AWT 18650 3400mAh 35A)I don't know about appropriate pre-heat setting for kanthal A1.Thanks. Link to comment Share on other sites More sharing options...
Spector NS5 RD Posted October 11, 2016 Report Share Posted October 11, 2016 welcome to the forum KonzKamz. i don't trust AWT's rating of 3400mah at 35A. this is most certainly FALSE and are not 35A, most likely 15A-20A. i would get better batteries, Sony VTC4, VTC5, VTC5A VTC6 / LG HD2, H2DC / Samsung 25R, 30Q - these are examples of proven batteries that work well at high wattage vaping in the DNA 75. also keep in mind the board generates a lot of heat when vaping above 60 watts. you can see this in Escribe's Device Monitor by watching the "Board Temp".Take a look at these recommended batteries from Battery Mooch....

retird Posted November 19, 2016 Report Share Posted November 19, 2016 So is it that the device gets hot at the battery area? Previous Hcigar VT75's had a cathode screw that when not tight would cause the case and battery to heat. The nano doesn't have the cathode screw but some report the device heating of the case and battery on the nano also. Some say cleaning the battery cap and threads of the device where the cap screws into helps with unwanted heating at the battery area. Some atty's get hot with use. Don't know if this is what you are seeing but just passing along some info....Good luck... Link to comment Share on other sites More sharing options...

NO WAY, I'm not saying it won't work, I'm saying it won't be safe to do so. Link to comment Share on other sites More sharing options...
VapingBad Posted November 26, 2016 Report Share Posted November 26, 2016 I don't think it is unsafe as the board will see how much it struggles to provide enough current and lower the power, but definitely not a suitable battery. Link to comment Share on other sites More sharing options...
