Guys, there are a couple other teardown videos of the Turbo 2 on Youtube, they're a simple search away and easy to find. The other two show how to disconnect the connectors and how to remove the battery. Apparently, the battery is stuck to the board with adhesive just like the back cover. And while it seems like you can remove the battery without taking the logic board off, it leaves a much smaller window for error and less surface area to pry it off. What a pain!
On the other hand though, I love this phone and anticipate keeping it for a long long time. Thanks to these videos I have confidence I can replace the battery myself when it goes bad.
