i already contacted them as said before, they asked me to send the board, but i couldnt remove it from the box

New update, got a brand new 510 but issue is still here, im start thinking the board must to be faulty.

http://www.esigarettaportal.it/forum/156-battery-box/61324-ufficiale-hcigar-vt75-nano-dna75?p=936693&ampviewfull=1#post936693 my phones battery died and i couldnt take any, i just did like him edit: after 3 hours of standby ohms cold ohms are rock solid (usually i was having a 0.01 ohm increase every hour of standby)

So ATM there are two possible way to fix this damn mod, the issue is caused by the not so proper connection between the atty gnd and the board ground (caused by a silly engineering by hcigar) overtime the 510 plate will oxidise and fucks up the gnd connection (crated by the 510 top plate, the black plate just down this one and mostly the entire body) First way to fix her (and easiest to do) is by remove a thin layer of the 510 black plate (just under the removable 510 hybrid plate) with some sand paper (i used 180) then wrap with an aluminium foil the outer part of the battery box (not the board part) till the inside, including the 510 (so in this way youre going to create a new conductive layer between the two parts of the body and between the two 510 plates) and then remove the excess over the positive 510 pin (just the center ofc) and battery. Second way (not so difficult but not so dumbproof like the first one) is to solder an electrical wire to the other ground connection on the board itself, peel the cable and leave it between the two 510 plates. plus if you want, add another one at the bottom of the board and leave it between the battery cap and the battery itself. (following this procedure you will have 4 wires in total soldered to the board instead of the original 2) For now i did the aluminium foil trick, will update in the next days/hours and see if there are still any resistance fluctuation overtime.

grazie compare, dopo vedo di farlo pure io appena torno a casa a Londra, non entravo piu su esigarettaportal da anni... Ops, sorry guys...

I was just going to ask if you find any improvement overtime... We should try with some noalox and see if it will keep up longer.

So, last week im back having issues with the ohms reading, decided to take it apart and found that one of the mounting screws was broken, the top left one, replaced it with a new m 1.4 x 5mm and tightened the other two, cleaned again the top 510 negative cap and is back working flawlessly. Must to admit now, this mod has a very great look, but the engineering is crap.

Thanks mate for the reply. Next week ill try to contact the seller and ask him about what to do to send this box for warranty, if it would be a problem with the 510 connector i should get the same issue on every fw im using, this happens only with the newer ones, i would like to think is a problem caused by the board instead of the 510.

Got this kind of problem in the past few days while using a kf5 clone, sorted them by just unscrewing, cleaning and screw back again the top part of the hybrid 510.

Updated to Sp5, still doing the same

Of course im not blaming Evolv, their support is amazing!

Didn't mention about the impossibility to remove the board from the case ??

So I'm not the only one... Spoke (again) with evolv support who asked me to send the board in USA, living in UK would be expensive, so I prefer to wait a new firmware and in case proceed with the lost vape support, nick from evolv didn't have any clue about this problem cause of course sounds crazy and illogical. Frankie what atty are you using? Ps: nick confirmed me there weren't any changes to the ohms reading between the old and the new firmware.

here is a video captured from escribe https://youtu.be/0jYGaPRBC50

Soldered again the ground post (and the chassis as well), still same problem...
