Anyone care to guess why my 850 mah battery is smoking when I connect it to my tracker... it also appears to have fused my 1st switch. I’m using 20 ga. wire and a Missile Works T3 if that helps.

After checking that, check the resistance in the altimeter from plus to minus and again from minus to plus. If available, make both checks with a meter in regular resistance mode and again in diode test mode. Report findings.
As long as black is - & red is + I’m still good. I’ve got to find my meter or go borrow one from F-in-L tonight / tomorrow.

Beware cheap leads from ebay and amazon. They're not always black - and red +
That’s potentially bad... yes I purchased batteries on Amazon.
Also easily checked once you have a meter in hand.

Batteries usually have the polarity right, it's the connectors that have issues. The ones I get from Amazon are right about half the time.
So... consulted the guy (F-in-L) with over 50 yrs experience in building & designing electronics. Reverse polarity on 2 of the 5 batteries I bought and my one switch is “old & leaky”. So problem(s) solved.
Can I suggest you go and buy a cheap digital multimeter? They are handy to have around and are so inexpensive these days.
Better still, F-in-L gave me a really nice one... he has a few. One of these days mine will turn up.

If you see smoke coming from a lipo battery - dispose of the battery immediately.
Much easier/cheaper to obtain a replacement battery instead of a replacement house.
Yes, I'm serious and yes lipo's require utmost respect.

If I have a suspect LiPo it either gets put on my mechanical workbench (6mm steel plate) or into a clay plant pot. If they are dodgy then they are not to be trusted, as you say.

If you dead short a lipo, it's done. Set it in a fireproof container for 24 hours and then take it to be recycled making sure they know it's a damaged lipo.
I know the airlines have regulations on them for a good reason... I dropped them off at Lowe’s recycling
Anyplace that takes batteries for recycling doesn't have the time to track which ones came in with user warnings that their damaged. A special bin where all of them are damaged sounds like a bad idea.
Me, assuming I have the fireproof container mentioned above, I'd restore that dead short then put the cell in the container. A thoroughly destroyed cell is much less dangerous than a damaged one that still has some charge. Like puncturing an empty rattle can.
Fortunately you didn't have a fire or worse.

I don't know that Li-polymer can be recycled at all.
One of the nearby HobbyTowns will take them. They discharge them completely (they put them in a bucket of electrolyte, iirc) and dispose of them.

I am not sure, but this type of smoking might be worse for you than the tobacco form of smoking.
The fire risk is why I charge my batteries is a fireproof box.
