Kastar V Mount 2-Pack BP-Y150W Battery and Dual D-Tap Charger

In this review the Kastar 2-Pack BP-Y150W V Mount Battery and Dual D-Tap Charger is evaluated for small production crews and solo shooters who need portable, camera-grade power. The bottom line: this kit combines two lightweight 100Wh V-Mount batteries with a dual D-Tap fast charger, making it a practical choice for on-the-go video work where weight, runtime and the ability to run or charge multiple devices matter. The reviewer found the batteries pleasantly compact and the charger flexible enough to power monitors, LED lights and V-mount gear directly.

Key Features

• Compact V-Mount design: Each battery measures about 4 in x 2.8 in x 3 in and weighs roughly 26.4 oz, making them easy to pack for location shoots or travel cases.
• 100Wh capacity: The 6.8Ah, 14.8V Li-ion cells provide substantial runtime for monitors and LED studio lights without exceeding common airline-friendly watt limits per battery.
• OLED display: The built-in OLED shows battery voltage, remaining capacity and USB output voltage so you can monitor charge status at a glance on set.
• Dual D-Tap fast charging: The charger can charge two high-capacity lithium batteries at once, helping reduce downtime between takes for busy shoots.
• Worldwide AC input and safety MCU: The charger accepts 110-240V AC and includes safety features that halt charging during improper voltage, short circuit or overheat conditions.
• 4-pin XLR DC output: The included 4-pin XLR adapter lets the charger supply DC power directly to camcorders or DSLRs, useful for extended studio runs.

Who It's For

This kit is aimed at independent filmmakers, ENG shooters and small production teams who need mobile V-mount power compatible with a wide range of monitors, LED lights and cameras. Its lightweight batteries and dual charging capability suit location days when carrying several spares and reducing gear weight is important.

Shooters who require factory-certified OEM batteries for critical rental workflows or those who need integrated camera battery charging solutions from a camera maker may prefer original-brand options. Also, if you need very long runtime beyond 100Wh per battery, larger capacity mounting systems would be a better fit.

Pros & Cons

Pros

• Good balance of capacity and weight, delivering wallet-friendly 100Wh V-mount runtime in a compact form.
• Dual-channel D-Tap charger lets you charge two batteries simultaneously and offers a 4-pin XLR output for direct device power.
• OLED battery readout and built-in safety MCU provide useful status info and protection during charging and use.

Cons

• At 100Wh each, the batteries are not the highest-capacity option if very long continuous runtime is required.
