Charging slowed due to low temperature

This is probably to save the Li-accu.
But it is a bad idea: If the temperature goes low, the sky becomes clear. I lost some beautiful nights!
Suggestion: Please skip the loading of the accu in deep temps. Drive the Raspi directly with the usb-input connector.
Then we could stargaze the whole cold night!

Exactly as it's implemented currently. If the temperature is low it doesn't charge internal battery and it doesn't use internal buttery. It runs on external USB power supply as long as it's available. 20Ah powerbank is usually enough for the whole night. And only when external supply is depleted it switches to the internal battery.

Lilo Exactly. Just have an external power source capable of supply enough power to run the heater (if you have it turned on) and everything else and enough capacity to last the night. Power consumed by the Seestar is less than 10W total, 120Wh for a 10hr night. Then the issue of charging below 0 deg C never comes up.

No, if the temp is low, there is no charging and S50 stops working!
I am googing to replace the battery with an USB cable. S50 accepts 5V. (Li-Ion-Accu: 4.4V)

Something is wrong with your seestar then.
