Please help with A7 RBA question

[Vapinshot]

Hi
I recently bought myself an A7 and I'm in the process of learning to rebuild the wicks.
Problem is I've read some advice (on other forums) that they really shouldn't be used on something like a twist or spinner, which is all I use at the moment. The issue seems to be that if you're not careful they can blow the battery. I'm checking the resistance with a multimeter (2.4 ohms) and making sure I haven't caused any shorts. Is that enough to ensure I don't blow my battery?

I've got my heart set on a Vamo which would obviously solve the issue, but really can't afford one just yet.
Can somebody put my mind at rest?

Thanks in advance

You could check the high amp safety cut out level for the battery and use an ohms law calculator to calculate your output

And check chart for optimum levels

Thanks Markfletcher007, that chart is very handy and I've saved it for future reference.
It looks like I should be fine at the ranges I normally vape at.
Not sure where I'd find out the high amp safety cut out levels for my batteries though I'll have to Google that! Bearing in mind that I'm using my mini vivis at 2.4 ohms I should imagine my homemade coil would be ok too. Probably just being a bit paranoid about cocking my first coil up!

Would suggest if you are using an atty at 2.4 you will possibly be ok, I don't really want to get off this really high fence I have found myself on !! But it would be good to move up to a device with safety cut off well for me anyway I cocked up my first few coils, too low and then too high but its a learning curve, what's the A7 like easy to rewick ?

I wouldn't be too concerned, 2.4 is just fine.
I think down to 1.8 would be as well.
I used Penelope on 1.6 ohm on my twist quite regularly, no issues and a pretty good vape indeed

You want to be careful not to short anything though, that would be my only concern.
The a7 is a surpringly good attie and so versatile.

Doh, just discovered how difficult it is to 'quote' on a tablet!
Markfletcher007 I'm finding the actual coil making the easy part of the job, the difficulty starts when trying to thread the coil legs through the holes. Cue lots of cursing! I'm actually pretty lucky cos I work at an electronics company so get to use the tools of the trade, including a brilliant microscope and excellent fine tipped tweezers........doesn't cure the swearing though! Still it gives my co-workers a laugh during lunchbreaks!

McAldo, it's reassuring to know you've used rebuilables on your twist, makes me feel a bit more confident about trying a lower resistance too

Thanks for your replies folks

Cool, if you ever feel like trying 1.4 ohm or a bit lower I'd suggest using either a mechanical mod with an IMR battery in (keeping an eye on the battery never to drop under 3.4v, that can be dangerous) or a VV with lots of Amps, for instance Juno from stigg, sweetvapes, even a vamo (that won't let you go too low for the resistance)

This said, a good coil on 2.4 will give you more space to play with, from very cool to quite warm, which can change the taste and feel massively.

I'm definitely in the market for a Vamo, unfortunately haven't been paid since before Christmas and when I do get paid Thursday the car tax and MOT is due!

Think I'll have to hold off till payday at the end of Feb

The A7 and Phoenix SS version are the same rebuildable, from what I can gather, and I agree it can be incredibly fiddly to thread the wires through the holes. Tweezers are your friend!
