i have two New batteries to suit a Jumbo UFO quadcopter , the machine burnt out a motor before i got to use them , so i returned it for a refund.
I got them from Banggood , they are for the WLtoys V262 RC Quadcopter - Spare Parts Battery V262-15 (SKU088983) .
They cost me $23.50 For the two.
Asking Price - $20.00 for the two , if you buy the Jaycar ones they will cost you $29.50 each !
This is the one i had , it came from - The Reject Shop.
