I learned a battery can stay 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 +

We dont have temperature control switches where i live
We need this device
If anyone can make this we need several billions of units
Endlessly
Hopefully someone is interested
