Two-pack Li-ion power for Phase One & Riegl

This Kastar BP-915G twin pack supplies two 7.4 V 3500 mAh lithium-ion batteries rated at 25.9 Wh each. They are built as direct replacements for a wide range of Phase One digital backs and the Riegl FG21-P, so medium-format shooters can keep shooting without hunting for proprietary cells.

Studios and field crews needing drop-in spares

Photographers who rely on Phase One P25 through P65+, IQ, IQ3, IQ4 or XF 70301 bodies, plus Riegl FG21-P operators, will find these packs match the original voltage and form factor. Users of other camera systems or those requiring a different voltage should look elsewhere.

7.4 V 3500 mAh 25.9 Wh per cell

Each battery delivers 7.4 volts and 3500 mAh for 25.9 watt-hours of capacity. That single figure determines whether the pack fits your power budget and runtime expectations for the listed Phase One and Riegl models.
