I learned a battery can be 45c forever
"Charging lithium-ion battery is possible in a temperature range of 10°C to +55°C. However, the charging should take place only at a battery temperature of +5°C to +45°C."
That is its charging temperature

So if someone got this battery

And a 45c to 40c reset thermostatic


And this 20ma hand crank



They can make a 20ma 45 celsius heater

Here's a article saying the same thing
