After it powered up again, the image was much much brighter. In the moment I briefly checked the previous recorded clip and saw that the ISO, WB, shutter speed, framerate, and aperture were the same in the clip I shot just before swapping batteries, as they were after, but the image was so much brighter now, it was un-useable.
My guess is that your screen went into power saving mode and dimmed down (that is set per default). After you powered up again your screen naturally went into the user set brightness level.
If the screen goes into power saving, just touch it and it will light up again - or you can switch this off altogether.
Probably your image had been too bright anyway before because if you were able later on to get a useful image from ISO 1250 and f14 it must have been very bright at your location.
Never judge your image from your screen alone - use the assisting tools the camera is offering:
* set the zebra to ON and 100% to see areas of sensor clipping
* watch the RGB levels in the lower left of the HUD
* use false color display to show you where your skin tones fall
Your camera has 2 gain stage ranges:
Stage 1: ISO 100 to ISO 1000
Stage 2: ISO 1250 to ISO 6400
Switching ISO inbetween a stage is just applying a different curve. As long as you shoot BRAW you will be able to change the ISO of a stage in post.
In direct sunlight I like to use ISO200, with the sun in the back I use ISO800, in well lit rooms ISO400 should do it most of the time. And in dimly lit rooms I switch to stage 2 with ISO1600 or 3200.
Don't use stage 2 if there is enough light - it will decrease your dynamic range by a stop.
To control your light levels use the built-in ND filters.

I didn't have much time to troubleshoot so I just reduced my ISO from 2000 to 1250 and stopped down the lens a LOT (like from 8.6 to 14). And then after shooting I had to pack up quickly from subject's house, so no time to troubleshoot again. It was fine even though my depth of field changed a little, client shouldn't notice lol.
Back at my studio I haven't been able to reproduce the issue, so I'm a little stumped - what's happened to me here? Any ideas?
In general I would recommend to you to take some time to study your camera, its manual and all the menu settings in depth. This will help you later when stress at a location kicks in to know what's going on when something starts to look strange and enables you to troubleshoot quickly.
