Kastar BP-915G four-battery kit

This kit supplies four lithium-ion BP-915G batteries and a matching AC wall charger. Each cell delivers 7.4 V and 3500 mAh for a 25.9 Wh rating. The charger accepts 100 to 240 V input and provides a 4.2 V 600 mA output with red and green LED status lights. The foldable flat plug makes the unit easy to pack.

Replaces Phase One original packs

The batteries fit Phase One P30, P30+, P40, P40+, P45, P45+, P65 and P65+ bodies as well as XF, IQ, IQ3, IQ4 and Riegl FG21-P systems. Swapping to this set restores full capacity when original packs no longer hold a charge. The jump is worth it when a shoot demands multiple fresh cells without access to mains power.

Suits medium-format photographers needing extended

Studio and field shooters who carry several bodies benefit from the four-pack layout and compact charger. Users who require higher-capacity cells, faster charge rates, or a different voltage platform should look at alternative power solutions.

Questions about this item

Will the BP-915G batteries fit the Phase One P45+ battery compartment?

The BP-915G is listed as a direct replacement for the Phase One P45, P45+ and P45 plus models, so it fits the original battery compartment.

How do I charge the four BP-915G packs with the included AC wall charger?

Plug the charger into any 100-240 V AC outlet, insert one battery; a red LED shows charging and green shows full charge — charge each pack sequentially.

What indicates a BP-915G battery needs replacement?

When a fully charged 7.4 V 3500 mAh pack no longer powers the camera for a practical shooting session, replace that battery.
