Compact, lightweight Kastar Mini V-Mount batteries (approx. 18.4 Oz) measure 4" x 2.8" x 2.2" (102 x 72 x 56 mm) and are easy to carry for field and on-the-go shooting. Battery type: Li-ion; Battery voltage: 14.8V; Capacity: 6.8Ah / 100Wh. Each cell features an OLED readout that reports battery voltage, remaining capacity and USB output voltage for quick status checks. The included Kastar Dual D-Tap fast charger is designed for any battery with a D-Tap socket — including BP-U65, BP-U68, BP-U100 batteries, V-Mount / V Lock batteries and Anton Bauer Gold Mount batteries that use a D-Tap input. It charges two high-capacity lithium-ion batteries at once. AC input supports worldwide voltages: AC 110-240V 50/60Hz 1.0A(Max.). DC output: high-power single-channel output at 16.8V 4.0A (Only one channel) or dual-channel at 16.8V 2A (two channels) when using both D-Tap cables. A 4-pin XLR DC output adapter is provided so you can power a camcorder or DSLR directly from the charger. Charge status is indicated by LEDs: green indicates standby or full charge, red indicates charging. The charger includes a built-in MCU that halts operation in the event of improper input voltage, a short circuit or overheating to help prevent overcharge and over-discharge.
