Four-battery pack for Phase One backs

This set supplies four 7.4 V lithium-ion cells rated at 3500 mAh and 25.9 Wh each, matching the BP-915G form factor used by Phase One P25 through P65+ and IQ series digital backs as well as the XF 70301 and Riegl FG21-P units.

Dual-slot USB charger with swappable plates

The included LTD2 charger powers two batteries simultaneously and accepts either Micro-USB or USB-C input at 5 V 2-3 A, delivering 4.2 V at 800 mA per slot while an LCD panel shows real-time capacity and charging status for each cell.

Tool-free swap and cable-only setup

Batteries click into the camera or charger without screws; the charger runs from any 15 W USB power source using the supplied Micro-USB cable, and the only common issue is forgetting to seat the battery fully so the contacts engage.

Questions about this item

How often will the BP-915G batteries need replacing?

Lithium-ion cells typically last several hundred charge cycles; with four 3500 mAh packs you can rotate them to extend overall service life.

What limits continuous shooting with the LTD2 charger?

The charger delivers 800 mA per slot, so two batteries take several hours to reach full capacity.

How much heat does the LTD2 charger produce during all-day use?

The 15 W input keeps the unit only slightly warm; no active cooling is required.
