I have 4 sets of TB50 batteries, I am unsure of the cycle count on these. I purchased a lot with a broken Inspire 2 hoping I could fix it. The bird was a total loss. The extra sets of batteries I am selling. This is the only thing I have left of the kit. Will sell all 4 sets, so 8 TB-50 batteries for $600 Shipped to the CONUS, Via UPS or FEDEX Ground. The batteries take a charge fine, not swollen. I was planning on keeping them to Purchase an Inspire 2 but have decided to downsize and go with a different bird. Or I would trade them for a Used Smart Controller. located in Smithfield Virginia USA.
