The Wilderness Systems Lithium Battery refines the kayak battery beyond the heavy and cumbersome marine batteries of the past. Lightweight and water resistant, the Lithium Battery not only excels in form but in function as well with multiple output options, superior efficiency, power and amp hours. The compact design conveniently stows in most kayak hatches.

The recommended limit for our battery is 12v, 1.0 Amp. This limit accommodates most popular fish finders but there are some exceptions. Fish finders that do not work well with the Lithium Battery typically exceed either the 12v or 1.0 Amp parameters. See the two popular examples below.
Garmin 73sv – current draw is 12v 1.41Ah. Ah is higher than our battery compatibility.
Lowrance 7TI – current draw is 13v 0.9Ah. Voltage is higher than our battery compatibility.
** Please note that if the battery shuts down while powering on your fish finder, the battery is performing as designed for your safety. In this case, the protection circuit is sensing over current demand and shutting the battery off. This prevents damage to the fish finder and prevents a hazardous situation with battery overdraw. Other competitive batteries do not feature the same protection as this one does.
