Batteries

Flight time is decided here, and the pack is the part of a build that wears out first. The 1S LAVA packs are for the 65mm and 75mm whoops on the drones shelf; the 1400mAh XT60 pack is for a larger quad. The 18650 and 21700 cells are Li-ion rather than LiPo, which is a different chemistry with a much lower discharge rate: they are for long range packs, goggles and controllers, not for a freestyle quad. Match the cell count and the connector to the aircraft before you order, because neither is something you can adapt safely after the fact.
