So it's winter and everything is cold as hell! Are 18650s prone to venting or any danger in cold temperatures? Let's say in a freezing cold car outside in 20F weather. I know heat is bad, is cold the same thing? Thanks guys!

18650s are usually OK in cold temps; assuming, you're not talking about insanely cold.
Lipo cells on the other hand can have some dangerous reactions to cold.
I won't fly my drone in anything lower than 20°F.; For that reason

Cool thanks! I'm so over cautious with my 18650s! Lol

I would worry more a but the power you are drawing from your batts than the weathers affect on them.

Each and every case of mod failure via venting i have seen was from... Operator errors. Not the weather. Not the manufacture. Not even due to rewraping.

They are almost all due to pulling more amps than the batts had to offer.

Oh yea definitely! I don't run mine anywhere close to their CDR. I mostly vape at around 60W on my RX200S (3 cell mod) and if my calculations are right, that's about 6.6A at 3.0V yea? But I'm over cautious about that too! lol
