I have seen number of negative comments on the WindCamp, also cost way too much.
I like the Bioenno LiFePO4s, they are excellent.? A 9AHr that will power the FT817 for many hours cost over $100, but I feel well worth it.? Can get LiFePO4s on Amazon for much less, I have one and has performed well, cannot say much more.? My Bioenno 9AHr has really worked out well, never run it down.? I've had for about 2 years.? Use for POTA.
