FPV attack drones burn through batteries in 15-20 minutes of combat, making high-discharge lithium cells a military supply constraint.

Military procurement now competes directly with consumer drone markets and Tesla-scale EV production for the same cell inventory, giving commercial battery suppliers leverage over military capability planning.
