Hi guys
My problem:
I have lifep04 batteries and I want to protect them from the cold… my idea is I want to measure the input charging voltage with ADC (this works)
if the input voltage rises (battery charger comes on above 12.5v ) and the outdoor temp is below 5c then the uni switches the 12v Heatpad on (Shelly 1plus controlling the Heatpad)
Will this work ??
