Compatible Phase One models

This two-pack of Kastar BP-915G lithium-ion batteries replaces the original power cells for Phase One IQ, Laser IQ, IQ3 and IQ4 digital backs as well as P25, P30, P40, P45 and P65 series cameras. Each 7.4 V, 3500 mAh unit delivers 25.9 Wh of capacity for extended shooting sessions. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating.

Upgrade from depleted or single spares

The pack is worth it when your current cells no longer hold a full day’s charge or when you rely on only one spare and risk downtime on location. Two fresh 25.9 Wh units restore the camera’s original run time and add redundancy so a single failure does not halt a session. UL1642 and CE tested cells also reduce the chance of unexpected shutdowns caused by ageing protection electronics.

Fits Phase One and Riegl systems

The batteries slot directly into the listed Phase One backs and the Riegl FG21-P without adapters, freeing you from proprietary chargers that tie up a single bay. Compact 3×2×2 inch dimensions leave room in a gear bag for cables, cards or a second two-pack. No camera-body modification is required, so the swap takes seconds and keeps the original weather sealing intact.

Questions about this item

Will the 3 × 2 × 2 inch BP-915G fit the Phase One IQ3 battery compartment?

The pack measures 3 by 2 by 2 inches and is listed as a direct replacement for the Phase One IQ3, so it matches the camera’s battery cavity dimensions.

How do I install the 7.4 V 3500 mAh Li-ion cells without triggering the protection circuit?

Insert each battery with the contacts aligned to the camera’s terminals; the built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection activates only if a fault is detected, not during normal insertion.

When should I replace the 25.9 Wh BP-915G pair after repeated charge cycles?

Replace the pair when run-time drops noticeably below the original 3500 mAh capacity or if the protection circuit shuts the pack down under normal load, indicating cell degradation.
