  • Automatic MCU protection stops charging on over-voltage, short circuit or overheat

Compact V-Mount Power Kit

The Kastar BP-150W kit delivers a 150Wh lithium-ion battery and a matching D-Tap charger in a single package. It is aimed at camera operators who need a portable 14.8V power source for compatible Sony V-Mount equipment. The bundle includes two batteries and one charger, simplifying field workflows for on-the-go shooting. An integrated OLED display shows voltage, capacity and USB output status at a glance.

Thermals and Charging Profile

The charger accepts worldwide AC input from 110V to 240V at 50/60Hz and provides a 16.8V 3.0A DC output. Indicator lights show green for standby and red while charging, with built-in MCU protection against improper voltage, short circuit and overheating. Automatic constant-current control prevents overcharging and over-discharging during normal use. The battery itself weighs approximately 26.4 ounces and measures 102 by 72 by 75.5 millimetres.

Sustained Load Behaviour

Under continuous draw the battery maintains its rated 6.8Ah capacity through the V-Mount interface and D-Tap output for accessories. The charger’s protection circuitry halts operation if sustained thermal limits are exceeded, resuming once conditions normalise. This kit does not serve users who require higher-capacity packs such as 190Wh models or multi-bay quick chargers for simultaneous charging. It also does not support cameras lacking a native V-Mount or DC-L10 adapter connection.

Questions about this item

How do I mount the BP-150W on a V-Lock plate and which orientation avoids the common latch error?

Slide the battery onto the V-Mount plate until the latch clicks; the OLED display should face outward so you can read voltage and capacity without removing the pack.

What part will need replacement first and after roughly how many cycles?

The Li-ion cells inside each 150Wh pack degrade after about 500 full cycles; the charger’s MCU and D-Tap port typically outlast the cells.

At what sustained draw does the charger’s 3.0 A limit become the bottleneck?

The charger delivers 16.8 V at 3.0 A, so any load above roughly 50 W will charge slower than the battery can supply.
