Battery safety.

[Jonshaw78]

Just a quick one, I might be in the wrong section for this but I'm sure a mod will move it if required.
If I was to build a coil above 1.2 ohms, would the battery type be an issue?
I only ask because I have 2 18350's that came with my Vamo V5, made by the same company, with these http://www.esmoke-ksd.com/cp_view.asp?id=111 batteries, I've also got a VTC4 18650 but if I wanterd to try out the shorty mode on a mod, would I be safe using that battery as long as I keep the resistance above 1.2 ohms?

If you're just using it in a Vamo it will be fine. Vamos are regulated devices and therefore will not fire below a certain resistance and above a certain amp limit.

No I'm using a Vanilla copper mech clone mate

So you want to use one of those cheapy 18350 batteries in a mech? Personally I wouldn't. Mech mods have no safety features so you are best off using quality, branded batteries.
It might be OK, but its a bit of a gamble in my eyes.

I dont particularly want to, just in theory. I fancied testing out the Vanilla clone in shorty mode, but I've only got the Vamo 18350's which are protected, I use a VTC's in my Mech when sub ohming I just wanted to know if it would be safe as long as I stay over 1 ohm resistance with the cheapies.

I didn't actually notice they were protected. They should be OK then (please don't blame me if it all goes wrong).

Protected batteries should be ok but the protection can be less safe than safer chemistry batteries apparently. .. not sure where on here I read this... keeping above 1 ohms should be fairly safe... and stop using if anything gets hot... disconnect batteries as well straight away if this happens. ... better batteries if you are using in 18350 mode longer term... but using some sensible precautions for a short term try out should mean that you don't over stress the battery.. it will never be entirely garuanteed but I know I have used some cheap protected ones before I knew there had been issues with some. .. always above 1ohms just found they didn't last anywhere near as long....

With a 1.2 ohm coil, you'll be pulling 3.5 amps. This would be considered by the vast majority of vapers to be very safe, even in a mech. What you need to do now is look up the safety information and see what their amperage draw limit is. If it's something around the 10 amp mark then you can vape away and not worry.

I'm not having a go at the OP here (it's not my style) but I find it very concerning to see people ask about battery safety where it's evident that they don't use their V=IR and P=IV formulae. I'm not trying to make anyone look daft here, I'm just trying to stress how much safer people would be if they did their research a wee bit and learned how ohms related to amperage draw.

Sorry for the soap box moment. I just want people to be safe, and how to know for themselves when their builds are safe.

I am pretty good with technical stuff, but I will be honest, the P=IV stuff just isn't clicking for me yet. I have read it all several times over but for some reason when it comes to the practical application of it, the logical progression just escapes me and I feel like I am reading it for the first time all over again. I have read a huge amount on battery safety and I am confident my set up is safe, but generally I am pretty good with numbers and I am struggling, I hate to think how someone crap with numbers would cope. It is always better to ask that to risk it, so you can expect a few similar questions from me as I get to grips with mechs.
