Those of you who are getting 'Motor Current' and 'Battery Overload' warnings when flying, I discovered one reason for it. NON-DJI propellers. I ordered a set (thinking they were authentic DJI props). They were actually 'RCstyle' props sold on Amazon. As soon as I flew with them I got both warnings. Put the DJI props on, and no warnings - even in Sport Mode with full climb and full forward. The message here is to use DJI props on all four motors.
