Accessory Information


The Heavy-Duty Lithium Battery refines the kayak battery beyond the heavy and cumbersome marine batteries of the past. Lightweight and water-resistant, the Heavy-Duty Lithium Battery for Fish Finders not only excels in form but in function, with multiple output options, superior efficiency, power and amp-hours. The compact design conveniently stows in most kayak hatches and accessory pods.

The single 12-volt port operates Fish Finders or other devices that require a continuous supply of power while the two 5-volt USB ports allow you to charge smaller devices such as phones, tablets and cameras.
