When I plug in the freshly charged battery, it gives me the, Not DJI Intelligent battery warning. Ive cleaned the contacts on both the battery and bird and still nothing. I've checked the springy connector too. The P2 powers up fine, but can't take off because of the battery warning. The battery telemetry on my monitor flashes between 12v and 0. I just replaced the shell, so I know that the internal battery connector is solid. My other battery works fine. I checked the battery with a meter and got over 12V, no load tho. I just bought a P4P and want to keep this as a backup, and rather not buy more batteries.
