battery damaged

So i see a lot of posts about replacing the battery pack in the Advanced and Pro remotes but noone seems to have asked or needed a replacement for the STandard. Can i just use any 18650 Lion with the same voltage? Anyone tried fitting ay larger sized batteries in there ?

I just got my Phantom 3 Standard in the mail yesterday and I read through everything, set it all up, and updated the firmware. I then proceeded to turn the phantom on and connect it to the DJI app and where it normally says "Safe to Fly", it said battery error. Does anyone know how to fix this...
