Compatible Power for Phase One Backs

The Kastar BP-915G three-pack supplies lithium-ion cells rated at 7.4 V and 3500 mAh, matching the voltage and capacity used by Phase One P25, P30, P40 and P65 series digital backs. Each battery stores 25.9 Wh of energy. The bundle is aimed at photographers who need reliable spares for long studio or location sessions.

Replaces Ageing OEM Cells

The pack replaces original batteries that no longer hold a full charge after repeated cycles. Swapping to fresh 3500 mAh units restores the runtime the back was designed for. The jump is worth it when a single charge no longer lasts through a typical shoot day or when the camera reports reduced capacity.

Dual-Bay USB Charger with LCD

The included LTD2 charger powers two batteries simultaneously from a 5 V 2-3 A source via Micro-USB or USB-C. Each bay delivers 4.2 V at 800 mA, and the LCD shows charge status and remaining capacity. Three batteries give enough rotation for extended work, though the single-cable input limits total throughput when both bays are occupied.

How do I correctly insert the batteries into the LTD2 charger so both charge simultaneously?

Align each BP-915G battery with its dedicated slot, press firmly until the contacts seat, then connect the charger via Micro-USB or Type-C to a 5 V 2–3 A source; the LCD will show dual 800 mA charging.

When should I replace the BP-915G batteries and what capacity loss is normal?

Each 7.4 V 3500 mAh Li-ion cell delivers 25.9 Wh new; plan replacement when runtime drops below roughly 70 % of original capacity after several hundred charge cycles.
