I am interested in buying a spare battery for my core - located near Madison WI
New ones can be purchased from Yarbo here. But, yes, checking the used market makes sense.
@vonny3 there’s currently a dude in Cali selling batteries for $529 each.
Got more details?
If you got to marketplace and search within 500 mi of LA it should come up. I don’t know the fella but feel free to reach out to him yourself.
