What to do with battery power outdoors?

Question

Electronics

I will make a low mast on the street for my projects (video surveillance, weather station, Wi-Fi, etc.). Everything is on solar panels (to begin with, there will be 2 jokes of 4W, in the future I will add). Bought one lithium ion bank 18650 for 3400 mAh.
Almost all equipment (TP-Link Wi-Fi access point, weather station modules, batteries) will be in a plastic hermetic box. So the question is: how will lithium-ion batteries feel there? In winter especially. There are frosts -20, but maybe -30 (it was a few years ago). Maybe there will be heat inside from heating the equipment? The access point gets warm during operation.
Or consider another type of battery?

Answer 1

Use acid batteries buried a meter and a half in the ground - in a sealed box. Good thermal stabilization, long life, if it is not flooded with water and if there is no permafrost

Answer 2

Or consider another type of battery?

Yes.
Lithium-ion will die very quickly even with underheating from technology.

Answer 3

Minus for them, insulate death with foam or ursa and make thermal heating.
I did such garbage for gas workers something like a thermos and inside the beagle bone battery pack and IR diodes plus a small fan

Answer 4

Yes, they will fall immediately. Why take the risk? It is better to transfer to a heated room. Burying is not an option, they will become damp.
