Kastar 2-Pack 14.8V 7800mAh (115Wh) Li-ion Battery with Dual D-Tap Charger + D-Tap-to-Sony Dummy for Sony A7S III (works with A7III) — Compatible with PMW-320K PMW-320L PMW-350K PMW-350L PMW-500

Portable 14.8V Li-ion power set designed for professional video and mirrorless cameras. Each battery measures 4.7" x 3.5" x 2" (120 x 90 x 50 mm) and weighs only 1.6 LB (720 g), making them easy to carry for location shoots. Capacity: 7800mAh / 115Wh. Four LED power indicators report remaining charge: 1 LED = 25%, 2 LEDs = 50%, 3 LEDs = 75%, 4 LEDs = 100%. Kastar Dual D-Tap (P-Tap) fast charger lets you recharge two D-Tap–equipped batteries at once. It supports batteries with D-Tap inputs including BP-U65, BP-U68, BP-U100, V-Mount / V Lock batteries and Anton Bauer Gold Mount batteries. The charger provides a DC output via two D-Tap cables and also includes a 4-pin XLR DC output adapter to power camcorders or DSLR cameras directly. Electrical specifications: AC input: Worldwide voltage AC 110-240V 50/60Hz 1.0A (Max.). DC output: 16.8V 4.0A (single channel high-power) or 16.8V 2A when both channels are in use. Indicator LEDs show charging status: Red = charging, Green = standby or fully charged. Safety and protection are handled by a built-in MCU that halts operation in the event of improper input voltage, short circuit or overheating, preventing overcharge and over-discharge. The package includes a D-Tap to Sony dummy battery so these batteries can be used with your Sony A7III while remaining fully compatible with the Sony A7S III.
