The B-mount Hot Swap Sharkfin Adapter Plate from Core SWX enables you to power your B-mount camera, light, or accessory continuously using two B-mount batteries. The sharkfin design mounts two batteries side by side, enabling you to remove a depleted battery while leaving the remaining battery connected, resulting in no downtime. This plate incorporates three D-Tap output ports for powering accessories. The plate accepts CoreSWX Helix batteries or third-party 14V B-mount batteries. Each D-Tap output provides unregulated 11 to 17 VDC simultaneous output, and the B-mount input/output to the device is unregulated 11 to 34 VDC. When using Helix batteries with this plate mounted onto a Helix battery plate, you can output dual voltage 11 to 17 and 22 to 34 VDC.
