The Core SWX Nano Gold Mount Battery is lightweight, reliable, and powerful. While the form-factor may be small, the Nano-series batteries can support up to 8-amp draws at 14.8V. The slim enclosure is great for gimbal balancing, as the camera it's mounted to can use the extra space for fore/aft movement.
 
Accessories can be connected to both the USB and D-tap power outputs, allowing the Nano-series batteries to act as a power hub for your entire rig, not just your camera. With the 98Wh capacity, a 25-watt load can be sustained for approximately 3.5 hours.
