The FPV-Power 12V 50Ah V3 Waterproof Lithium Battery with 10A Charger delivers long-lasting, high-capacity power for kayaks and marine electronics in a rugged, compact, IP67-rated design.
This Regulator is designed to be used with fishfinders needing a minimum of 11V to run. The reason is that at 11V, the battery will still have between 1/4 to 1/3 capacity left however the fishfinder will cut out as it hits its minimum operating voltage.
