Never worry about battery issues again!!

Buy a 3-way perko or battery install kit. Designed specifically to work with your marine electronics to give you the best clean power source in the industry. This system also gives you backup to your 16V battery. With the flip of a switch, instantly switch your graph and transducers over to your 12v cranking battery as a backup source of power.

If you don't currently have a dedicated power harness

If you are starting from scratch, we recommend you buy the battery install kit, this kit has everything you need to tie the 12v and 16v batteries together thru the 3 way perko switch. Then buy a Sonar Pro Harness that fits your boat needs or if you build yourself, you can find the premade fuse holders to add to your system at the perko and elimate the factory fuse holders on your graphs and modules.

If you already have a dedicated wiring harness

If you already have a dedicated wiring harness like SEACLEAR, SONOR PRO'S, or your own wiring system, you will only need our Battery install kit which will include 4 battery cables to connect to 12v and 16v battery, 3 way perko switch and grounding lug. Then you use the wiring system of your choice. If you make your own wiring then you can do just a 3-way perko.

Also, pick up grounding lugs and positive lugs as needed along with premade 10awg fuse holders with waterproof connections.
