My heads last for weeks Djs, you doing the clearo ' swoosh ' to keep the wicks well wet and avoid the burnt taste?

I know, it's bloomin odd.

I had a nice chat with a vendor on here and he reckoned I'd get ages out of them, no trouble.

What happens is I swoosh/tilt often, then 12-24 hours in, the hits get dry (spicy/harsh), so I take them apart.

Then, they either bounce back to life with a dry burn or I find an area of blackened wick. Sometimes I can wash this out, others it fails.

I can live with the dry burning and losing a fair proportion, that's cool (I can afford it...££) but as I said I'm down to my last head and after that it's just the dozen or so I rewicked myself.

and that's scaring me on anything that might fry itself.....

So, it's either get another battery that is 99% safe to use regardless, or just invest in replacement heads.

I don't feel ready for a big old tube mod, but a twist is £22 (if that's safe) and a lavatube is £60, which is £38 more. That's only 4 x 5 packs of heads??

Yep, Vamo looks the cheapest. Lavatube £25 body only (beware of cheap copies). Garry Dibley dunno, maybe £20 without batteries & charger, and need 2*18650.

There's a vendor near me doing these...

vapourhut.com/mods

I could pop over for a Lavatube (complete kit) maybe?

[fagin]

E Cig Wizard have (hopefully still) the black mini Lavatubes for £15. Couple of batteries and a charger and you're set.

My "ego" is a Riva.

I also have a Vision Spinner.

(and endless E-Lites and JacVapour kit).

The problem I am fast running up against is that from about tomorrow (maybe another day) I'll be out of original replacement heads for mini nova/CE5.

That means only really using the Spinner, unless I risk the Riva. The trouble with the Riva I fried was that I tested a nova for resistance and continuity (is that right?) put it on the Riva and killed it about 10 puffs later.

Looking inside the housing of these replaceable heads, a tweak one way or t'other with a wire can short it and that's why I could do with 2 batteries that can withstand this.

Not fussed about mah/size/design, but need to make a choice soon.

Leaning towards an eGo Twist in all honesty, as some Spinners have cashed in their chips and taken an early bath.

Is it possible that it isnt your coils at all, but the tube that the coils screw into. If there was an intermittent short inside the tube you may get what you are encountering. Do you have another Nova?

I was thinking also the ego battery you have if its not joyetech usually push out around 4.1 or 4.2v at first then go down as the battery discharges, so maybe with certain heads its giving quite high voltage?
Also with a lavatube you can lower the voltage or increase as you like, maybe lowering it on certain ohms will be a good vape and make the coil last longer. Its good to go with a mod with good protection though with the rebuildables in case theres a short though and the vamo will be good cos it has the ohms tester, sometimes the quoted resistance can be lower or higher so it can give u a good idea of what voltage is safe to go for at least for keeping the heads good long term, plus the vamo is good value and has mini mode.
lavatube is a bit shorter than the vamo, even I think the mini mode is shorter than mini vamo so if you dont mind not having the ohms and would like a shorter mod, the £15 offer is very good.

I have 2 novas. Different models too.....(both mini, but not the same)

I rewicked the last remaining heads knocking around my spares box. All of them got the right ohms reading and all beeped on the continuity test.

Trouble is, I'd need to replicate the "short" and then test the head on the other nova.....

all of which is risking more batteries though?

unless the Spinner is 100% safe.... ???

If the same is happening with both Novas then it almost certainly rules out the centre tube

Personally if I am dry burning or checking coils I always use a simple battery mod with a decent protected battery in it. No electronics to fry and if the battery is shorted it can easily be re-set by sticking it in a charger. A reasonable battery mod will last for a very long time and so will the battery. It will vape at least as well as an eGo type battery as well

[vapee]

The ego twist shouldn't fire if thers a short coming from the atty, apparently someone even tested it by shorting the battery and it didnt fire and worked after. Its possible some of the clone batteries use a different system then and wont work after the short but just protect the battery from problems. The one from VE is a nice battery, not sure exactly whether it has the same protection as the ego twist - the vision spinner I think should have.
oh and alibaba appears in the results cos every vendor selling there (mostly from china) has about 300 versions of the same product using all names they could think of hehe

Buy a £3 multimeter from Ebay then you can test your coils before you put them on a battery, cheap & easy.

Earlier in the thread it was mentioned about "hard Short protection built into the PCB" this basically means that a link in the PCB will fail like a (non replaceable) fuse, so the battery cannot over discharge and damage the battery in a way that could make it react dangerously. However the battery/pcb assembly is then only good for the bin.

I have a tester. I tested them all. I put it on my Riva, it vaped and then fried.

Currently pricing up mini lavatube. Looking like £15 for the mini body only and £18 for a battery (18350) and charger (xtar)

[djs]

Lavatube and batteries ordered.

I'll keep my Riva (the remaining one) for cartos and T3s only.

Thanks to everyone, maybe not such a bad end to the *terrible* day I had.

Am I right in assuming though Des that a decent protected battery will re-set after an external short because it uses a PTC which cuts the current when it heats up and then works again when it cools down?

[DiscoDes]

Yes, some use a PTC but most Ego types only have a sacrificial link.
