Four-battery kit for Phase One backs

The Kastar BP-915G set includes four lithium-ion batteries and an LTD2 dual charger, built for Phase One P25, P25+, P30, P30+, P40, P40+ and compatible IQ-series digital backs. Each cell delivers 7.4 V and 3500 mAh for 25.9 Wh capacity, giving shooters a full day of reserve power in the field.

Dual-slot charger with USB-C and Micro-USB

The LTD2 unit accepts 5 V at 2–3 A through either Micro-USB or Type-C inputs and can charge two batteries simultaneously at 4.2 V, 800 mA per slot. An LCD panel shows real-time capacity and status, while interchangeable plates let the same charger serve other battery types without extra cables.

25.9 Wh per cell for extended sessions

Four packs at 3500 mAh each provide enough headroom for long studio or location shoots without swapping cells mid-session. The 800 mA charge rate means a depleted pair reaches full capacity in a few hours, so overnight charging readies the kit for the next day. Not suited for systems requiring higher-voltage packs or faster charge cycles.
