Yes it came with three barrels that fit. Polarity was good as well. Just set the thing to 16v and away you go. Ran it for 8 hours off this battery and still had 30% left. Also here is a really cheap but useful stand for setting up on rocks and stuff. https://www.amazon.com/gp/product/B081VHQCTR/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
Here it is in action. You can see the stand towards the middle of the vid when the drone flies around it.
