DJI Tello Dron Repair not charge, doesn't want to work : Fix 

I presume that device is a custom charger of sorts? Does it just jump start the cell voltage regardless of monitoring current and float levels?

IN WHAT PINES YOU CONNECT ?

Will my tello drone and battery still work even though i havent used it in 9 months? its still in the unopened box. I havent open the box yet. the box is sealed for 9 months.

What kind of charger are you using in this video

My drone is not working at all . When I charge it and play with it ,it is working . Give a solution please

What type of charger is it

Hi, i have exactly the same problem with yours. My battery will not charge due to a very long time that it was not charged. Where can i buy that kind of charger?
