Now your results may vary, but I was itching to see how long I could actually run my Garmin Striker 4 with my Nocqua Pro Power Kit 10Ah battery. The Striker draws a max of .23A and recommends at least 10V for the fish finder. I was actually shocked on how long the battery powered the fish finder down to 10V.
I also show why I chose a lithium Ion battery over other types.
