Hello, I am deploying Wisblock in outdoor locations enclosed in waterproof container. I am powering the system with 18650 li-ion battery (3.7V, 5000mAh) and charging with small 5V solar panel connected to solar input jack on Wisblock.
This is working perfectly so far. But I understand that it is not good to charge the battery when it is extremely cold (< 0C). I also have the temperature/humidity sensor installed on the Wisblock. Can I enable/disable the charging circuit from within the Wisblock code, based on temperature to help avoid damage to the battery?
