High-discharge LiPo cells above 75C come from only 3 factories in Dongguan

FPV drones require lithium polymer cells rated at 75C+ continuous discharge to sustain the 100A+ current draws during aggressive maneuvering. Only three factories in Dongguan, China (supplying brands like CNHL, Tattu, and GNB) produce cells at this discharge rating. Western cell manufacturers (Samsung SDI, LG, Panasonic) focus on high-energy-density cells for EVs and consumer electronics at 3-5C ratings. A supply disruption or export restriction from China would halt military FPV drone production worldwide. This persists because high-C-rate cells sacrifice energy density for power density -- the opposite of what the EV market wants -- so Western cell R&D ignores this niche entirely.
