Kastar BP-915G 4-pack for Phase One and Riegl

This 4-pack of Kastar BP-915G lithium-ion batteries is built for Phase One P40, P40+, P45, P45+, P65, P65+ and XF 70301 cameras as well as the Riegl FG21-P. Each cell delivers 25.9 Wh at 7.4 V with a 3500 mAh rating. Professional photographers and survey operators who need multiple reliable spares for long field sessions will find the pack convenient.

Simple drop-in replacement with built-in protection

Installation is a direct swap: remove the depleted pack and insert the Kastar unit in its place. No tools or firmware steps are required. The integrated circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. The only common issue is forgetting to fully charge all four packs before a multi-day shoot, which reduces available runtime.

Verify the exact model name on your camera

Before ordering, confirm that your body is listed as Phase One P40, P40+, P45, P45+, P65, P65+, XF 70301 or Riegl FG21-P. Earlier P25, P30 or IQ-series models are not covered by this pack. Check that your charger accepts 7.4 V lithium-ion cells rated at 25.9 Wh so the new batteries charge correctly.
