Grains of table salt vary slightly in size, but three average grains stacked together adds up to approximately one mm. If three grains equal one millimeter in length, then a single grain is approximately 0.3 mm or 0.03 cm on a side.

Apparently the throw of the Paps V4 is 0.3mm

Thats a short throw...

I had my headphones in and left my mech unlocked (doesn't fire usually, paps v4).
Took my headphones out picked up the mech, really hot.
I've put it outside to cool down (with the atty I'm using :nah:), it's well safe at 1.2 with an AW 18490 battery. Will it just have drained the battery?
Will I be able to use it once it's cooled down and charged again?

Man, :facepalm:
No. You should dump the battery AND the mod. That mod is a problem if it fired on a flat surface. Or repair it if you have the skills and knowledge to do so.

No, not at all. The mod is fine.
Literally a grain of salt left on the table under the switch is all you need to fire it.

0.3mm throw! You've got one yeah? Fantastic mod but look at this

That's me actually pressing and firing the mod!

That's me not pressing!

The only time I ever had a mod fire accidentally was probably 4 years ago. It was a Paps. At the time, I was into mechanical tubes, and I had my Paps with me at the time. We were at our local flea market, and had stopped at the food court to eat. I set the mod down on the table, and had neglected to turn the lock ring. I didn't think of it, because the Paps, even when not locked, was designed to be able to stand on end without firing. But apparently, I had set it down on a bread crumb, or something, and it was just large enough to activate the switch. The Paps switch throw is so short, it's almost a touch switch. Fortunately, I eventually heard it firing. I grabbed it quickly, and either unscrewed the atty, or the top cap. I don't remember which. But the tube got extremely hot. Too hot to hold.

Zut, never bet against a trend.
Dump a paps? Oh no,,
Missed out on the v4 @ Sitty..

I know. I'll be taking this to the grave :)
I'm 27 atm so hopefully that's a long time as long as I get to grips with this locking ring and not forget those pesky grains of salt! :-x

Okay. It's at 3.66 now and I think I overestimated in the firing time probably somewhere around 3.8 when it began.
Checked it. In perfect condition looks wise.

@Mooch if your around I'd appreciate your opinion

Thanks
180 degrees Fahrenheit.

That's the temp you need to watch for on most batteries.

2 volts to 2.5 volts depending on the particular cell.

That's the damage threshold.

It's almost guaranteed that battery is perfectly good.

Matter of fact, I'm just going to say keep it and watch for excessive heat the next few times it's used.

Internet battery experts really should learn what they're talking about before giving advice.

These guys saying to get rid of it... ask them what proper disposal consists of.

Bet they mostly can't answer.

:glare:

And that's potentially as dangerous as keeping it. Especially if it's perfectly good and still holding a charge as it seems.

Me, I put several layers of blue masking tape over each terminal, wrap them in bubble wrap and put into a Qt. freezer bag labeled lithium cells. They go into the recycle bin at The Orange Box store that sells all things hardware related :)

The battery should be perfectly fine. These batteries are usually rated to go as low as 2.5-2.75v.

Put a 1 ohm load on them for 24 hours first.

Aw man...
Too late. Wrapped it up in electrical tape, took it too the tip and disposed of it in the old, used battery box.
Damn...

Gotcha. A buddy I used to fly RC with used to put his old packs in a bucket of salt water for week. I burn nitro fuel in my planes.
Turns out on a lot of packs that creates electrolysis that simply eats away the terminals leaving the pack completely live but won't read anything on a meter.

I consider this more dangerous as its a false sense of security.

One might be inclined to do something to the pack they'd otherwise refrain from assuming it's safe.

This is how I discharge my lipos...

I do one cell at a time to ensure each cell is depleted.

I got the bulb at a junk yard for free while picking up parts.

Just clipped the wire and kept the connector to put leads on.

Then soldered banana leads to that and a jst-xh connector.

@DC2 Here ya go, buddy.

Well Mooch had a different suggestion than I so getting rid of the battery was probably the right thing to do :)

Wanted to add.

When this procedure is complete, the cell is basically inert.

Ready for disassembly if you wish.

Indeed. Does seem as though he is the battery boss.
Plus, what's done is done.

I wouldn't fancy driving back to the rubbish tip and rummaging through a box of old, used, discarded batteries.
I don't think it's a good look ;)
