Help me avoid blowing my hand off please

[steffijade]

Well.. I've had the chance to have a bit of a play with me new toys this afternoon and made some progress.

Ordered some likely looking candidates for replacement screws on the Taifun at the link Blackhack posted (tyvm luv) and tried another coil on the Kayfun with a lower ohmage (came out @ 1.3ohms).

Unfortunately, the wicking doesn't seem to be able to keep up with my 'greedy' vaping style at that sort of ohmage on the Kayfun (I've experimented a bit with opening what I assume to be the juice flow control sleeve a touch, but I think this just gets tightened back down when I screw the top back on). May have to stick to 'normal' range ohmage coils on this and use it on VV/VW devices.

I have however, managed to get the Nemesis working properly and the Carvella too (after a fashion.. battery space is quite tight and have had to use flat tops combined with a couple of those excellent OCD washers from Rob at stealthvape, screwing out the centre pin on the atty a touch and winding out the mod centre pin too). Not exactly an ideal workaround, but it does actually work without constantly firing now... may have to try and find some shorter length batteries if I'm gonna use it regularly.

Having got the Nemesis to work, I decided to chuck the Fogger on top of it and see how it fared. Have to say, I've been pretty much blown away by the result... lots of flavour and vapour and it keeps up well with my chain vaping. I'm really impressed, so much so that I ordered another of each this afternoon (both from UK suppliers this time though, so hopefully, no 8 week interlude). Been using my Efest batteries with one of those 'safety circuit' jobbies for a few hours and not managed to blow me hand off (yet), so the Nemesis/Fogger combo is looking like a big win for me... even worth the 8 week wait.

My new concern though, is battery overdischarge.

Any handy hints/tips on avoiding draining the IMR batts down too far (other than the obvious regular checking of voltage) please?

Thank you for the tips so far guys.. much appreciated.

Keep em coming.. this bimbo needs all the advice she can get.

Good to hear you got it going. Wicking on the kayfun, I use cotton, I'm running a .7ohm twisted kanthal build without issue, follow riptrippers youtube guide, it works fine.

You wont run your cells too low. Take one of your attys that will fire on a vv mod. Set mod to 3.4v you'll get nothing out of it, flat flavour no vapour. You'll get the same on your mech at 3.6v tbh. Soon as vape tapers off charge cell, easy. You may even find your changing em out at 3.7v tbh.

Cell fitting. If your panasonic cells are protected, they have a wrap, then a brass trace than another wrap to insulate, their bigger than 18mm I can only fit unprotected cells in most of my mechs.

For the aqua. I've posted a mini review/build log. My build was .9ohm, I'm rebuilding tonight aiming for .6ohm, I like a warm vape is my only excuse for this, my taifun is also going down to .6/.7 for the same reason. I'll probably put a twisted build in that to get the ohms low.

I use Panasonic 18650 pd's for .6ohm and above, very high capacity for vaping cells and an icr/imr hybrid, they hold their voltage well under load.

For silly builds I really rate samsung inr18650 cells, extremely low voltage sag under load and they dont get warm even when chain vaping at .3ohm.

I also posted a how do you dip your wick thread, , lots of builds in there and I'm hoping some other people will add their builds to it, the idea being it can be a resource for people.

I've tried a few silly builds but tbh, my go to set up for any device is a micro coil style coil and cotton, I then work from there to decide what I want/need from the device. I am liking twisted builds, the coils are very robust and you can just pull the cotton, dry burn and wash then rewick without damaging the coils, they don't need to be silly low resistance, just twist .2 kanthal and use a couple more wraps to up your resistance.

Have fun steffijade and dont hesitate to holler if you think I can help.

Well. I got both the taifun and the aqua to read .5ohm on the vamo which is .6ohm in reality. I used .45 kanthal, which is like bloody fence wire but gives nice solid micro coils and stays where you want it. I do really rate using more wraps of much thicker kanthal, its easier to work with for a start. No pictures as my phone was on charge but I got two attys coiled and wicked and one rewicked in 3/4 of an hour.

I like a warm vape because I much prefer desert juices, got fruition in the aqua and its not really doing it for me, should have put strawberry cream tart in.

Thanks gords1001 , it's been a while since I last used an unregulated device (original Siam mods cube) so I'm a bit rusty. Was a bit worried that low voltage might still be enough to kick out enough watts at lowish ohms for me not to notice until the batt had started to dip into overdischarge. Didn't even think to take voltage drop into consideration.

The battery issue with the Carvella was the length... not sure if the clone is just a bit undersized, length wise (ooh er don't titter missus).

The Aqua still looks a bit daunting tbh... the grub screws and dual coil thing will probably have to wait until I'm feeling brave enough.

On the subject of dual coils.. the way I understand it, you have to double the required ohmage on both coils to get the desired ohmage (like if I was aiming for 1ohm dual coil, I'd have to do 2 coils at 2ohms). Have I got this correct or are the 'voices' leading me astray again?

I'll check out the build threads and the kayfun vid and see if I cant edumacate meself a bit more.

Do you happen to have a vendor linky for those panasonics by any chance please?

Tyvm for all of this btw.. much appreciated.

My caravela clone is hit & miss on battery length with both 18500 & 18650's. Either too long or too short. I believe they're known for it.

The coil thing, yes, you're right. 2x 2ohm coils = 1ohm final.

The batteries. I can't quote real figures so you're right to look at that but i use my torchy 18500 batts (Unknown serial No) with no issues at 1ohm & above. Also the panasonic (Torchy branded) 18650 / 3400mah & again only above 1ohm.
I made the decision recently to get around any doubt & i bought a new sony vtc4. I reckon in future when my batteries want replacing i'll go for those highly recommended ones, they cost a bit more but the quality is there.
I'd like to know what the top dog is in 18500 batteries because i like my mech mods in that size.

steffijade, see this linky link http://www.kritikalmass.net/battery-calculator/index.php

Lots of fabulously fab info on current ratings, some calculators and c ratings too...

Great stuff, tyvm.

steffijade I've been using ecolux shop on ebay, they keep panasonic 18650 pf cells which are the updated version, I got two this month but my friebd was given them for his mech I got him they worked well with my .6ohm builds so I'm convinced that they are genuine (ecolux also sends cells with a safe usage sheet whicg I like) I also got all four of my samsung inr18650 15m cells from them and they are working fine at .3ohm, I have no qualms recimmending them as a cell supplier.

As vaporsizer confirms yes dual coils halve the resistance. If you don't have it vapers toolbox is a usefull app if your on android, I dont know of an ios equivalent, I dont do apple.

The aqua is to me a really easy platform to build on but I do a lot of dual coil builds, familiarity helps I guess. Its a thirsty bugger at .6ohm I'll tell you that.

Looks like I'll have to keep fiddling/adjusting the Carvella clone then.

Thank you for the info.

That link that Tubbyengineer put up to the battery specs looks pretty damn good for checking safe usage limits, perhaps that might help you find the 18500 you're looking for?

Nice one, thanks gords1001 ... will check out ecolux when I get some more batts.

Next line of enquiry... wicks.

I've tried a few builds using silica/ekowool but found that the wicks got shredded whilst screwing down the juice control? chamber. Cotton seems to be better in this respect, but I'd imagine it's not quite as durable as silica. How often is it recommended to change the wick if using cotton please? Like every refill?.. after a certain amount of liquid has been put through it? or is it just pretty much suck it and see?
