I have a brand new Gens Ace 4S 5300mAh 30C battery.
Bought it a while back but it is too big for my copter.
Completely unused, and has been on storage since I have it.
I also replaced the Deans connector with an XT60.

Asking 4700 + Shipping for it.

Bump.
Price reduced to 4500 + Shipping.
This is the least price, so please don't negotiate now.

Another bump.

Sold.
