kypom 1800 mah 3s used quite a bit. works fine. selling for 400
tattu 3s 650 mah 2 * pcs available... bought for 950 each i think ..selling for 450 each
the tattus must have just 20 cycles on them but i have kept them unused for 3-4 months so they have puffed very slightly. but work great.

reason for sale? i no longer fly airplanes. so these will not be any good to  me in the foreseeable future
similarly
