An on-board electric power supply and recharging system for electric rotorcraft. The system has two modular lithium based battery packs (MLBBP) a, a hydrogen fuel cell and hydrogen fuel tank b to support power delivery/supply to the battery packs when under heavy load, such as during take-off, landing, emergency manoeuvres, etc., multiple external air vents c, utilising the Venturi effect and Bernoulli principle to provide air flow to associated turbines d, the turbines then turning permanent magnet generators (PMG) that recharge the battery packs. When the battery pack powering the rotorcraft is drained below a set threshold, the supply is switched to the next battery pack, and the first battery pack enters a recharge cycle.
