Compatible Camera Power Kit

This bundle supplies two lithium-ion cells and a dual-bay USB charger for Phase One IQ, IQ3, IQ4 and P-series digital backs plus Riegl FG21-P laser scanners. Photographers and survey professionals who need spare power for long field sessions can carry both batteries in the compact pack. The charger accepts Micro-USB or Type-C input so it can run from common power banks or wall adapters.

3500 mAh 7.4 V Li-Ion Cells

Each BP-915G battery delivers 3500 mAh at 7.4 V for a total of 25.9 Wh capacity. That single figure determines whether the pack matches the original equipment specification for the listed Phase One and Riegl models. No other voltage or chemistry is offered in this kit.

Cool Low-Draw Charging

The LTD2 charger draws 5 V at 2-3 A (15 W) and outputs 4.2 V at 800 mA per bay when charging two cells together. With no fan and minimal current the unit stays silent and barely warm during typical recharge cycles.

Questions about this item

How long will the 3500mAh capacity last on a Phase One IQ back?

The two 7.4 V 3500 mAh packs deliver 25.9 Wh each, giving a full day of typical capture sessions on an IQ3 or IQ4 back before needing a swap.

What does the USB-C and Micro-USB input actually limit?

The charger draws 5 V at up to 3 A (15 W) and outputs 4.2 V at 800 mA per slot, so charge speed is capped by that 800 mA rate per battery.

Will the charger plates fit the Riegl FG21-P battery cavity?

The bundle includes swappable plates sized for the BP-915G form factor used by the FG21-P, FG21P and Phase One IQ series backs.
