V-Mount 150Wh Kit

The Kastar BP-150W kit delivers 150Wh of Li-Ion power in a compact V-Mount form factor. It includes two batteries and a D-Tap charger, designed for camera operators and monitor users who need portable, high-capacity energy for extended shoots. Compatible models cover cinema cameras and production monitors from Kinefinity, Vaxis, Lilliput and SWIT.

14.8V 16.8V Charging Limits

Each battery operates at 14.8V with a 6.8Ah capacity, while the charger accepts worldwide AC 110-240V input and outputs 16.8V at 3.0A. The D-Tap interface governs both charging and power delivery, so devices must support this connection type. Built-in MCU protection stops operation during improper voltage, short circuit or overheat conditions.

150Wh Capacity Decides Fit

The single specification that determines suitability is the 150Wh rating, which sets the runtime ceiling for attached equipment. Users needing longer continuous operation without battery swaps must evaluate whether this capacity meets their load profile. It is not for productions requiring higher watt-hour packs or non-V-Mount mounting systems.

Questions about this item

Should I pick the 150Wh V-Mount kit or a smaller capacity for the Vaxis Storm 058 Pro?

The kit includes two 150Wh batteries, each rated at 14.8V and 6.8Ah, giving extended run-time for the 5.5-inch monitor and similar V-Mount devices.

What does 150Wh mean for actual shooting time on a Vaxis Storm 058 Pro?

At 14.8V and 6.8Ah, a single battery can deliver 150 watt-hours; real-world run-time depends on the monitor’s power draw, but the capacity supports many hours of typical 5.5-inch wireless operation.

Does the included D-Tap charger work on 110–240V mains worldwide?

Yes, the charger accepts AC 110-240V 50/60Hz 0.8A input and outputs 16.8V at 3.0A, with automatic constant-current control and MCU protection against overcharge, short circuit and overheating.
