Rooftop is my preferable SKY mount location but not so easy to access in my elder age! While i appreciate the engineering allowing 1 year battery life, replacement every year (set for 1s reporting) will be a hassle even if there ARE no moving parts! My old Davis wind unit with solar panel had this advantage.
I was thinking about running 2 wires out the bottom of SKY in lieu of AA batteries and powering with an easily constructed 18650 Li-on battery(s), TP4056 solar charge module, and perhaps 3.7-to-3.0v buck converter.
I’d appreciate thoughts from folks with more electronics background than I!
