Long days on the water with little downtime means you need a long-lasting, heavy-duty power solution - which is precisely where this battery comes in. Featuring more than twice the runtime of Jackson Kayak's 9.6Ah battery, this is the perfect battery combo for the most demanding conditions. Includes a 22Ah 24V K2 lithium battery, charger, battery bag, 9” x 5 Pitch 24V Prop optimized for use with the 24V lithium battery, shear pin, allen key, screw, prop hub, two ¼” heat shrink insulated ring terminals and Owners Manual. The K2 Lithium Ion 22Ah 24V Battery is significantly lighter than lead acid and offers excellent charge and discharge cycles, and when it is in the battery bag it is both waterproof and floats. Internal circuit boards protect the batteries, provide a charging circuit, and equalize the cells. This battery fits perfectly in the hatches of the Big Rig FD, Blue Sky Boatworks 360 Angler, Cruise FD, and Coosa FD! Lithium ion batteries are smaller, lighter, feature constant power and energy, are faster-charging and are longer lasting over their lifetime vs a deep cycle battery option.
