In this video you see how you can transform a battery from Syma X8C / X8HC / X8W / X8HW to be used for the MJX Bugs 3.
You will have to cut the banana connector and solder a XT30 connector.
The one that I am using lasts longer than the original MJX battery. (surprise :)? )
I have beginner soldering skills, please try to do that better than me.
With the added cost of the transformation this battery is worth not more than 12 USD, which is almost 3 times less than the original battery's price (price comparison as of march 2017).
EDIT June 2017 - there already are offerings that are close to the 20 USD range, use the links below to purchase a new original battery
