Power for Phase One backs

Two Kastar BP-915G lithium-ion batteries rated at 3500mAh and 7.4V each deliver 25.9Wh of capacity for Phase One P30, P30+, P40, P40+, P45, P45+ and P65 digital backs. The pack suits photographers who need reliable replacement power for studio or location work with these specific camera systems.

Voltage and chemistry match

Each cell is a 7.4V lithium-ion unit built to the BP-915G specification, ensuring the correct voltage and chemistry for the listed Phase One models. Using a battery with a different voltage or chemistry would prevent the back from operating, so this exact match is the deciding specification.

Foldable AC charger included

The bundled wall charger accepts 100 to 240V AC input at 50 to 60Hz and outputs 4.2V at 600mA DC, with a foldable flat plug for compact storage. LED indicators show red while charging and green when the batteries reach full charge or standby, letting users confirm status at a glance.

Questions about this item

What does the 25.9 Wh rating mean for actual shooting time?

Each 7.4 V, 3500 mAh cell stores 25.9 Wh, giving a full day of typical studio work on Phase One P30, P40, P45 or P65 series backs.

What does the charger’s 4.2 V, 600 mA output limit in practice?

The wall unit delivers 4.2 V at 600 mA, so each battery takes several hours to reach full charge from empty.

Will the 3×2×2 inch pack fit the P40+ battery compartment?

Yes, the BP-915G cells match the original dimensions and slide directly into P30, P30+, P40, P40+, P45, P45+, P65 and P65+ backs.
