I take a look at how to size fishfinder battery for kayak using the power draw of the most popular kayak fish finders from Garmin, Lowrance, and Humminbird. In this setup, I compare the ability of a traditional sealed lead acid battery with a modern lithium LifePO4 battery that costs about the same. You need enough capacity to last for an entire trip to get the most use out of your fish finder, making proper sizing important! #goldenmate
