Multiple Battery Mission

I'm still not quite sure how multiple battery missions are supposed to work...

Let's say it starts to rain half-way through a mission. I switch to "P", regain manual control and bring my Phantom 3 back home. Could someone outline the steps as to how I set everything up to return to the point where I left off and finish the mission?

Just had my first (unintended) 2 Battery mission. This was probably due to wind at the site.
App announced that aircraft was returning to home at the start of the first leg after the Low Battery warning initiated (30%) this was still short of the 16 min flight time I had set in the flight plan options. I think perhaps the app may have worked out it couldn't complete the leg within the 16 min?

The aircraft commenced returning to home at mission altitude. Whilst I'm not 100% sure but I believe that part way home the aircraft stopped (I'll need to check the log). I simply took over and flew the bird home.
As I descended I got some saying flight complete with a number (I think it 1,2,3,5,4) which I ignored.
Switched to a fully charged battery.
Took off manually as per the start of a normal mission. pressed upload and then start as per normal.
Off it went and picked up on the leg where it stopped. I could have sworn it took images as it flew to the re-start point, but haven't checked the folder yet and I did have an issue with one image when uploading to MME.
Mostly a straightforward process with a couple of little hiccups that weren't show stoppers.

Thanks for posts... this helps! So, my understanding is that only pushing the "Go Home" button in the Flight Control pullout (top right) or the Return to Home button on the remote control creates an abandonment point. Flipping the switch from "F" to "P" (to regain manual control) does not create an abandonment point... is this correct? I think this is what was causing my problem in trying to restart the mission.

Correct. The battery running out will also create one.

Correct.

I just tried swapping batteries yesterday. When my first battery got down to 30% I tapped the "go home" icon on the app. My Phantom 3 Pro flew back over to home point, marked this as the abandonment point, then proceeded to descend. I swapped out batteries and relaunched. It flew up to the assigned altitude, then proceeded to snap pictures as it made a beeline for the end of the grid line it was on, when I had recalled it. So it basically skipped half of a "column" on the grid--the same "column" it was in the process of flying when I recalled it home.

Is there something I did wrong? Should I have waited till it got to the end of a column on the grid?

I then tried re-flying the whole mission (estimated at 16 minutes), but couldn't figure out how to get the mission to upload again, (after several power cycling and takeoffs and landings) until I decided to try switching the RC off and then on again. By then, I'd eaten through to 50% of my second battery power, and didn't have enough juice to re-fly the mission. I guess from reading elsewhere, perhaps if a mission fails to upload, I should instead just unplug the USB cable and plug back in again.
