The Through Hull Panel Connector is compatible with YakAttack and Nocqua Lithium Battery Kits. This kit provides the ability to run your power connection through the hull of your kayak/boat, hatch, or some type of battery box or container. For example, you could store a YakAttack/Nocqua battery on the inside of a Bonafide Kayaks DryPod or YakAtack BlackPak Pro and have a quick disconnect port for your power cable located on the outside. The Through Hull Panel Connector features a tethered cap that allows for quick connectivity of your devices power cable when in use and creates a water tight seal with not in use. The tag end of the panel connector is 4 in length. For instillation a 5/8 hole is required and stainless steel hardware is included.
