Poor mans battery warmer

Just a diy job here to keep my batteries warm in the field in the winter. Hopefully it should last an hour or so. I’ll get something better when I can, but I like diy’ing in the first instance. It uses hand warmers.

Toasty :hotsprings:

I keep my batteries in my pockets…

See. I was thinking that. @AndyCortez said armpits. Then I thought of down my trollies. But originally I thought of up my acehole. My arse is far too petite for 6 lipos. :rofl:

Only thing you gonna need to watch out for is condensation

True. Now I know what to do with all those silica packs I get with the 3d print rolls I get. Better put them in the oven now!

I have this coolbox with a heat mode. Haven’t had to use it to warm batteries yet, just chill beers.
