Selling out of the hobby again. These two batteries are Thunder Power, G6 series, 5 cell, 5000 MAH, 65C, lipo batteries. They have only been charged via a balancer!!! Both batteries have maybe 6 charges and flights on them for my TREX 700 F3C aerial photography platform. I built it a few years back and never finished it. Batteries have been stored properly. If I had to guess they are maybe 3.5-4 years old, with 6 cycles on them! Very nice batteries and cared for properly. 45.00 each, 90.00 for the pair. Hopefully local purchase only, but I may be ok with shipping these batteries!
