Pro-B4 1000 Air UK The tough and robust Pro battery pack

Product number: 901084-UK

This is quite simply the fastest and toughest battery pack on the market. The Pro-B4 is a battery pack that delivers studio performance on location.

The Pro-B4 is a state of the art battery pack that in some regards outperforms even the best studio packs out there. It’s a revolution on location in that it can freeze motion at 1/25,000 a second and fire up to 30 flashes in a second.


  • Very short flash durations on all power settings.
  • Selectable FREEZE mode available for extreme splash shots.
  • The world’s fastest recycling battery pack allowing you to create never before seen sequence shots on location.
  • Li-Ion (LiFe) battery recharges to full power in only 45 minutes.
  • Battery can be charged while in use, which makes the pack equally useful in the studio.
  • Two individual outputs and 11 f-stop power range with control in 0.1 f-stop steps provides unbeaten precision and versatility on location.
  • Can be wirelessly controlled from up to a 300 m range with any optional Air Remote.
