A hybrid light tower includes an engine, a permanent magnet generator configured to be driven by the engine, a battery pack including a plurality of lithium-ion battery cells, an extendible mast configured to move between a lowered position and a raised position, and a light assembly including a plurality of light emitting diodes. The generator is configured to produce a first DC power. The battery pack is directly electrically coupled to the generator to receive the first DC power from the generator to charge the battery pack. The light assembly is coupled to the mast and the light emitting diodes electrically coupled to the battery pack to receive a second DC power from the battery pack. The light tower does not include a battery charger connected to the battery pack.
