What is the SKY Battery Drop Out Voltage?
I’m down to 2.86V, Anker Alkaline, probably not the best choice for winter (although we have been unusually warm this year), but I had a pack and they have a good reputation for not leaking (they were on sale too): https://www.amazon.com/gp/product/B07RHX78P8/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
(I have Lithiums in the AIR unit)
How low can the SKY voltage go while still maintaining proper operation?
