So i decided to use the traxxas 5000mah lipo battery on my upair one drone. it works great so i made a carrier for the battery that just slides in like the original. In order to use the traxxas battery i had to use my dremmel and cut the connector down the middle and then i built in to the battery tray a holder for those connectors so it just slides right in.
still working out the kinks on this so bear with me
Update 04/05/17- was able to modify the deign and get it to function as intended.
here is it working
This is where i purchased the battery
