here is the flight record. I can't open it up to see the motor speeds and stuff like that just not sure how to do that
The minor cell voltage differences had nothing to do with the incident.

You were hovering normally and gave the Mavic a touch of throttle to climb an extra two feet when 175 feet up, at 4:02.8 something happens.
The drone pitched 73° .
At the same time it rolled left 122°, started spinning anti-clockwise and losing altitude.
You left the joysticks centred and as the drone fell further, the falling, pitching, rolling and spinning all became less severe.
At 4:12.6 and 22 feet higher than the launch point, the drone started to gain height. The joysticks were still centred.
The drone reached 51 feet at 4:16.2 and appeared to have almost stabilised when it all started again.
The drone fell tumbling and climbed again, the climb being fairly stable.
The drone stabilised at 4:23.7 at a height of 21 feet.
You flew it until 7:41 when you landed safely.
This incident looks pretty strange.
It's odd that the drone recovered and climbed, particularly without any control inputs from you.
I've not seen anything like it and can't think of a likely cause.
