Okay... It will work until it doesn't. These are not meant to be soldered on.

If you must... Very high heat. Flux, pre-tin and work fast. Much eye protection and whatever you do don't breath in the dust after they blow.
It is time we stop accepting the things we cannot change, and start changing the things we cannot accept...

SKU 3935902 is a 10 amp battery. These IMO are not good enough.

1- The voltage drop can get it under 3 volt.
2- You run at battery max specs. This shorten the life of the batteries.
3- We are talking about soldering i.e. non easily replaceable.

To solder the battery follow the Vapor's recommendation or buy this flux SKU 1260004.

I'm just going to stick with this one.

I replaced the one in my buddies fine. He had to "help" as I didn't have the right Screwdriver size.

What's wrong with a 10A continuous power cell in a 30W iStick that won't draw over 10A to begin with?

30W @ .4oHm is 8.7A (ish) so even on a low charge you're probably still going stay under 10A draw... Oh and they're rated to handle down to 2.5V under load.

In vaping terms, BTW, that's running it at half it's maximum rated output.

Wrong. The ohms law used for mech mods does not apply for batteries in regulated mods.

The law here is: (Watts into the board) = (Watts to the coil) minus conversion losses of course.

If you are pushing 30 watts to the coil then the board has to pull a little more than 30 watts from the battery.
This is called the conservation of energy law.

If that battery has less than 3 volt then the board is pulling more than 10 amp from the battery.

Not to mention overhead for some longevity out of the battery.

8.7A + 15% is still 9.9A...

You're also likely wrongly assuming that someone would use an iStick 30@ @ the minimum resistance and max power at all times...

Would you drive a ferarri full throttle at all times?

I really doubt it. And even if you do, we're talking about the difference between the power cell lasting 2 years, and 1.5 years. It's still Panasonic technology, and still the safest chemistry there is for power cells.

You guys are getting dangerously close to fear-mongering here :-\

Awesome ;-)

I would understand a little fear education if OP was trying to use ICR chemistry, an unknown rewrap, or a fire brand cell, but that's not the case here. We're talking about cells from a couple of the big 4 manufacturers that are all pretty well known for borderline overly conservative ratings.

@johnny_469

For me is clear that your self confidence is way bigger that your technical knowledge.
Therefore, any effort that I will make here to teach you the facts will be vain.

That means that I do not want to argue with you.

My advice to you is: read again my previous post. You may learn something from it.

I suggest you never try to engineer a mod. You're wrong.
