It just seems like you're creating your own definition of AC with its own peculiar set of ramification. If I plug my battery into my charger, which gets its power source from the 120VAC wall outlet,...

Is it? If you hook a battery up to an h-bridge and reverse the polarity continuously and fast enough you get an output that acts like AC and can do all the things AC can do but DC can't do. You can...

If you find that answer on that let me know because honestly I don't know why. Most likely marketing and application specific historical baggage.

You mean like in this video? At 7:40 you can see the waveform generated by his 3 phase power supply, and at 9:12 you can see him use that supply to drive a BLDC motor. Spoiler alert: the motor spins....

Thankfully yes. I was afraid I'd end up having to re-bind my receivers but fortunately that wasn't the case.

I'm going to have to start walking back my praise of the NB4 after what happened to me last night.

The current does alternate. On any single wire, the current can flow in either direction based on the state of motor commutation. It's how the ESCs are designed to work. I suggest you watch a youtube...
