You don't need a wiring diagram, dismantle the old battery carefully, photograph the connections and annote them so that you know what goes where and you have your 'wiring diagram'. DJI will almost certainly NOT supply one.
ONE MAJOR POINT, jumper the new battery pack to the control board BEFORE you disconnect ANY of the old cells.
If the controll board sees the voltage drop below a certain amount it will switch some chips to open circuit and render the battery useless even with new cells.
Thanks i did know the + and - contact but not what the other pins do and have tried to replace the cells but lost power so bm modual failed. Also did not have a mini welder to join batt cells. It would be better to be able to use 4s or 6s batts as they are cheaper. |
