Need help rebuilding protank head

[WestonG91]

Hey,

So, I have a Unitank and I recently purchased some 2.5mm VooDoo Wool (silica) and .32mm Kanthal A1 wire.

I only have a 1100 mAH Ego battery at the moment as my mod broke. I believe it operates at 3.7v but I'm not certain. The 2.5 Ohm heads that came with the Unitank worked well with this battery, so I'd like to recreate a similar resistance.

I tried a 6 wrap build using the .32mm wire and 2.5mm silica. I used a needle and wrapped the wire around both it and the wick. This build fires up and vapes but the tank/battery gets quite hot after a few tokes. I have no way of checking Ohms, so It may be that the resistance is too low.

I was wondering if anyone has an idea of how I can try to reliably create a 2.5-ish Ohm head with the materials I have?

Try doing 7-8 wraps on a 5/64 drillbit. Then feed the silica through. 30 gauge microcoils are my preference with the protanks. Especially with organic cotton. Cotton gives a better flavor.
Look at rip trippers videos on youtube. He has a good protank rebuild tutorial. He uses 28g but the idea is the same. Hope this helps

Hello!

I can tell you how to get 2.5ohms almost every time. You do know that you are risking your battery by not having a multi meter....??

Get one for £4 or something. Better than playing Russian Roulette with your expensive gear.

Get a MM or atleast an ohm checker before building your coils.
You could have a short or sub ohm, which egostyle can't handle.

Are you sure you're using .32 gauge wire? 5-6 wraps should put you well within the 2.2-2.5 ohm range that you seek.

I use a paperclip when I redo my heads and do it similar to how you just did. Only I use 3mm silica on the paperclip, give 'er a good 5 wraps and fit it into the head. Once it's all snug and secure with the insulator and pin, I then remove the paperclip.

Yeah, it's defo .32 gauge. I bought it specifically because I was told (like you said) that 6 wraps should give me around 2.5 Ohm.

OK,

I decided to charge the battery for a couple hours (this battery gives no indication of charge level -_-). After that, it wasn't getting nearly as hot but then started leaking whenever I took a large drag. I opened the head and added a flavour wick and it's vaping great now - no leaks. Still gets fairly warm after a short chain vape but nothing to worry about. Pretty happy with the 6 wrap .32 kanthal and 2.5 silica build. Of course I still have no way of proving what the resistance actually is, but it'll do for now. I'm going to buy a new VW mod soon that can Ohm check.

Thanks for the replies, especially retired1. It at least confirmed that I was using the right build and saved me a lot of potential messing around trying different builds.
