Compact V-Mount Power Kit

The Kastar BP-150W kit supplies two 150Wh lithium-ion batteries and a matching D-Tap charger for Sony DSR-400 and DSR-450WS series camcorders. Each cell delivers 14.8V at 6.8Ah in a 4 x 2.8 x 3 inch form factor weighing 26.4 oz. An integrated OLED panel reports voltage, remaining capacity and USB output status during operation.

150Wh Capacity per Battery

The 150Wh rating determines how long a compatible camcorder can record before a swap is needed. Two cells are included so one can charge while the other powers the camera. The charger accepts 110-240V AC input and provides 16.8V at 3.0A DC output with red and green status LEDs for charge monitoring.

Charger Protection and Thermal Control

The charger incorporates an MCU that halts operation on improper input voltage, short circuit or overheat conditions. Automatic constant-current control prevents overcharge, overdischarge and electronic shock during fast charging. Green LEDs indicate standby, red LEDs indicate active charging, and the circuit stops automatically when each battery reaches full capacity.

Questions about this item

How long will the 150Wh capacity run a typical camcorder drawing 30W?

At 30W continuous draw the 150Wh pack delivers about five hours; actual time varies with the camera's power profile and any accessories connected through the D-Tap port.

What does the D-Tap output on the charger provide and what voltage does it deliver?

The charger supplies 16.8V at 3.0A through its D-Tap connection, enabling fast charging of compatible V-Mount batteries while protecting against overcharge and short circuit.

Will the 102 x 72 x 75.5 mm battery fit a standard V-Mount plate on a Sony DSR-450WS?

Yes, the pack conforms to the V-Mount form factor and is listed as compatible with the DSR-450WS, so it locks onto the camera's standard V-Mount plate without adapters.
