So I connected some wires and everything works as I’d expect. However, I decided to look further and found a part of the board where I can directly get power from the battery. It may be possible to use a transistor and use the LED switch to power something from the battery while still having the ability to turn it on or off. A picture of where I found you can get the power from is attached however I haven’t tested this with the drone on so I wouldn’t recommend doing it unless you’re really sure and have great soldering skills.

So I soldered it on. If anyone does this a few notes:
-There seems to be some coating on the battery connection pins. I just burned them away by putting a bead of solder on my iron and putting it against it for about 10 seconds, then waiting 30, and repeating until it all burns away
-The leftmost pin is covered by a piece of plastic which i cut away, however DO NOT cut the thicker part as that probably is more of a structural part.
-The wires of the XT30 connector I used are thicker than the pins so it was very difficult to solder them on, make sure they only connect to one pin
-My XT30 connecter just barely fit through the vent so if you use anything bigger be sure to put the wires through before soldering
-The wires won’t fit around the fan so I had to put them through the right air vent (the left would work too)
-It may prevent your drone from fully folding
-You should probably put tape over either parts of the metal heatsync above the battery pins or over the pins themselves to prevent a short.
-This will definitely void your warranty
To do it you’ll have to take off the bottom of the drone and remove the bottom-most board (the one with the fan on it). At the back part of the board there are the battery pins. Before you solder, break off one of the air vents/filters by cutting the wide parts of the plastic off. The bottom ones are inaccessible but once you get the top four you can (carefully) wiggle it off. Then put the wires through the hole in the vent and solder them in the way I showed in the other reply. Re-assemble and you should be good. Remember, it’s always on when the drone is on.
