For the battery cycling, my approach was:
Make sure it is drained in one cycle.
Initially, I would just pop the full battery in the AC, turn it on (not armed - rotors stopped), and let it run itself right down - with a VERY small voltage draw. But, I was impatient and I was only doing one per night.
So I switched to flying my AC down to ~5%.
I don't think working the batteries hard (high voltage draw) any lower than that is a good idea for longer term battery health - and if I were to do it again, might have even stopped at 10%.
When it landed and disarmed (rotors stopped), I just left the AC on to finish the rest of the battery off.
Haven't charged them up yet, but that felt like the best approach for me.
