Killed my Phantom Vision Battery
Urgh.
I haven't used my DJI Phantom Vision for a good few months. Last time I used it the battey was pretty low.
Decided I want to take it for a flight today and the damn battery won't charge. Seems you are not supposed to let the "smart battery" get too low or there won't be enough charge to get it going.
So now I guess I am selling the quad as not working, spending a fortune on a new battery or trying to get charge in another way like using a 9v battery and connecting the terminals. The problem is I don't know which is the positive and negative terminal.
Any electrical knowledgeable guys know how to check.
