I'm well aware of Mooch's blog - in fact, that's the reason I chose this forum over any others
I eventually ordered from Fogstar as they seemed to be well-regarded from trawling across the internet. My point about Amazon was simply that its shocking how badly regulated the selling of batteries on there is, which I realised soon enough not to order any batteries from there.
Papergoblin, much the same point really - it sickens me that products are being mislabeled on Amazon, let alone that fakes are also floating around. Money over safety, capitalism at its finest eh...
With regards to calculating coil ohms I use the Vapetool Pro app for a kind of rough guide and figure that my coils should come out near to the mark when actually measured. It seems good for any of the build styles it has built in but not for custom builds. For instance twisting two claptons together which it just can't fathom. For these builds I would just measure it once its all put together and throw it away if it comes out less than 0.2 - but I've realised that this really isn't as foolproof as I had thought so I'm sticking to making builds that the app works with from now on. I can't really justify a small improvement in flavour at the expense of uncertainty.
"Also when using a calculator, set up you measurement with shorter legs, like 1mm length instead of 3mm. This will get the calculator to add more wraps to the coil, it may make you coil come in at a higher ohm, but that is safer than a lower." (I can't figure out how to quote two people in one post...)
What do you mean here? Surely putting in a shorter leg length will just reduce the ohms calculated compared to the real coil? Is the idea that the calculated value will always be +/-
X ohms from the real coil so by putting in shorter leg length in the calculations you know it will definitely give a lower value than the real coil i.e. if it comes out at 0.25 with full leg length the real coil may be 0.1-0.4 and potentially unsafe, whereas with shorter leg length entered into the calculation then if it says 0.25 the real coil would be more likely 0.2-0.45? (Numbers clearly pulled out of my .... to illustrate the point) If not that then I'm confused by what you mean.
