Ready power for Phase One backs

The Kastar BP-915G kit delivers four 7.4 V 3500 mAh lithium-ion cells plus a folding-plug AC charger, giving Phase One IQ, IQ3, IQ4 and P-series digital-back shooters a complete spare-power set for long studio or location days.

Charger limited to 600 mA output

The wall unit accepts 100 to 240 V input but supplies only 4.2 V at 600 mA, so each depleted cell needs several hours to reach the green-light full-charge state; plan charging cycles accordingly.

Simple swap but watch the LED

Batteries drop into the back without tools and the charger shows red while charging and green when ready; the only common slip is leaving a pack on the charger after the green light appears, which adds no extra capacity.
