Hi guys , recently bought my son a jxd509g quadcopter and with it coming with only one battery I purchased some more off amazon. Now the one that came with the quad lasts around six minutes where as these last a max of 2 mins one lasted24 seconds. Was wondering if this is normal. They are 3.7v 600mah. Or if you can recommend any better batteries.
Kind regards
David.
