I Recently bought a new setup, Nemesis Clone for Hcgar, and a plume veil 1.5. I'm using sony VTC4 lMR batterys charged with a Nightcore digicharger D2. (Overcharge/dis protection) I assumed I would be fine with this setup, but I wanted more imput. As well as the fact my smoktech Vapesafe fuse 7 wont fire on my current dual parallel 24 gauge .4 ohm build. Just want some solid input, is it not firing because its unsafe or?
Just Double checking, My setup is safe?

Didnt work because that SmokTech Vapesafe will trip for anything beyond 7 amp.
With 0.4 ohm setup and freshly charged battery say 4.2v you are drawing 10.5amp
So if you wanna use that SmokTech, set you atty at above 0.6ohm
Without that SmokTech, and original / authentic Sony vtc5 can go "technically" safe up to 0.15ohm in pulse.
Technically as in based on specification, but all batteries have their own variance.
If you are new to mechanical mod. please please try to understand ohm's law and limit of your battery. Yes that Vapesafe will protect you but in the long run if you decided not to use that, you can either have a good vape or a blow up battery.

Hi and welcome to the board. Reference to the Ohm's Law Calculator tells me your .4 coil on a Nemi (assuming full charge 4.2 volts) is drawing 10.5 amps. Your Vapesafe certainly should be opening up at that loading. Are you sure you bought real (not counterfeit) Sony VTC4's? Those are about the best conveniently available for a mech mod, IMHO. They are nominally 20 Amp batteries which, according to @Mooch 's bench tests, can be loaded to 30 amps without destructive temperature rise, although so doing damages them. I personally feel I prefer a 50% safety factor on my batteries, meaning I try not to get a one-battery mech up over 10 amps with my own VTC4s. That said, I can't honestly say I am certain 10.5 amps is "unsafe." It is obviously well within the 20 amp rating. But it does shave the safety margin a skosh tighter than I personally like. You'll have to make the call on that. For my part, I don't build a mech load for a one battery mod below .5 ohms. I do think, however, if you take the Vapesafe out, it should probably fire-- it's not easy to break a Nemi, I have several of them-- and without too much sputtering. However, if you want to use your Vapesafe, you need to keep your coils up above .6 or so to keep the amps under 7.
I have an ohms reader, which is tested .4 ohms, I don't plan on going any lower than 3. It fires just fine without the fuse, just wasent sure the resistance needed for it to not fire with the current setup. I just wanted to make sure I had a decent setup without super immediate "stop everything that's not safe" kind of danger, thanks for the input all,
No sweat. That's not a "call the fire department" kind of thing. Happy vaping
