Battery voltage queries + others!

Right thanks for that guys, just one more thing then ..................... can anyone recommend a good heat gun or blowtorch that is available in the UK? I would prefer an electric one rather than gas powered if possible just to save having gas cannisters hanging around the house, also it needs to be small enough to heat the coil without melting my fingers ....... any ideas and what do you guys use?

Thanks in advance

I use a gas one. You could get a "jet lighter" from your local pound store perhaps? I don't think an electric one would get the coil hot enough. Or you could do what many do and hold it in your gas cooker flame (with a pair of pliers etc). If you're on electric, then I'm out of ideas!

Hi Des

Ok just wondered which gas one do you use?

[DiscoDes]

I got one of THESE I got from China but you can get them on Ebay. It's got several features that make ideal for heating coils.
1. A stand built in, leaving 2 hands free.
2. Adjustable flame.
3. A igniter so you don't have to hunt around for matches.
4. on-off valve

I got a small blowtorch from homebargins, works a treat £5.99 and a quid for gas

No worries matey, anything you need to know just shout or ask on here and we'll all try out best to help you out

While a lot of people heat their coils and press them together a lt of people don't bother. It's not strictly necessary and I personally can't tell the difference in vape quality. Give it a shot with and without and see what you prefer or if you can tell the difference.

Your efest batteries will be absolutely fine to use unless you plan on using extremely low ohms. I have used them in a dripper with 0.4 ohm coils safely although they don't last long between charges then.
If you aren't familiar with ohms law I would suggest using an online calculator to work out the draw on your batteries at given resistances until you are familiar with them. Just remember your batteries are 4.2 volts off the charger so that's the figure you need to use to work it out.

I think that whether or not you heat your wire before making a coil depends on what type of coil you want to make. I find that if I am making a normal coil for a silica wick for some types and thicknesses of wire it is worth heating up the wire to reduce its "springiness" - I just run a lighter over it a few times (you want the wire to glow red). You only really need a blow torch type arrangement if you are making mesh coils - to oxidise the mesh.

These days I mainly make micro coils and use cotton and you don't need to heat up the wire at all for this.

As already mentioned if you actually want to measure the voltage drop you need an inline voltmeter with a 510 connection - very handy little devices and quite cheap.
