Yep, Align doesn't include a battery with it. From what I've learned so far, it requires a li-po 3S1P 1900-2300mah at least 16C with deans connectors, which I have been having trouble finding. Seriously, every battery I find meets all of those requirements except for the last one. I'm buying this starter on Tuesday, I hope I find a battery by then so I can get them at the same time.
