I am in the process of planning the electrical layout and install for my new Hobie Pro Angler 14. This is not a 'keep it simple' kayak. Instead, this is a 'as close as I'm coming to a bass boat for a while' kayak, so it may seem like overkill. I won't necessarily have all of this on the kayak all the time, but I like the option to have it when I want it. As I've gotten older, I take these projects a bit slower and more methodical and know enough to know I don't know everything and try to research as much as I can. I wanted to run my plans by the group to see if I'm missing anything or can do something better. Additionally writing out my plans helps me think things through. I've corrected 2 issues so far in typing this out. I should draw all this out next.
At the currently planned end state, the kayak will have a Motorguide Xi3 36" saltwater pinpoint trolling motor mounted on the bow, Lowrance HDS Pro (10" or 12" depending on where I end up mounting it), Lowrance Active Target 2, Lowrance S3100, and likely at a minimum one of those pole 360 degree lights and maybe some additional lighting. For the trolling motor there will be an Ionic 125AH LiFePo and for the electronics/lights another Ionic battery, thinking a 100AH one (based on 6.5a max draw of the HDS Pro/AT2/S3100, gives me 2 full days of fishing on single charge, likely more than that).
Trolling motor setup - the 125AH Ionic LiFePo, 6 AWG marine grade wiring, 60A fuse close to the positive terminal (finally found inline fuse holders with 6 AWG leads), then an Anderson type quick connect. Negative lead from battery will go to same Anderson type quick connect, allowing me to remove battery box for easier charging indoors. Probably should put a battery disconnect switch in there before the plug? From that Anderson quick connect the positive line will run to a 60A circuit breaker and then to another Anderson quick connect up front where the trolling motor will connect. Has anyone used that insanely expensive Minn Kota connector? Worth it? The ground will run to the same Anderson quick connect. I'd like to put a relay in as well so I can rig up a fall overboard safety pin deal on power to the motor. The accessory/activate lead for the relay will run to some version of the Yak Attack power switching box and between the two is where I'll insert the motor safety kill switch. Yak Attack makes an auto reset breaker/relay but it's 50A and the trolling motor manual says 50A would work, but 60A would be better. I haven't yet found a 60A breaker/relay combo. Anyone know of one? Based on wiring charts I believe the 6 AWG wire is large enough for the run of say 10ft or so from behind seat to front cockpit area. Am I missing anything here? Any suggestions for improvement?
Electronics - the likely 100AH Ionic LiFePo, 6 AWG marine grade wiring, 30Aish fuse close to the positive terminal, then Anderson type quick connect. Negative lead from battery will go to the same Anderson type quick connect, again allowing me to remove the battery box for easier charging indoors. From there the positive line will run to a Blue Sea Systems water resistant fuse block. The negative line will run to a Blue Sea Systems water resistant bus bar. Power for the Yak Attack power switching module will come off the fuse block with a 20A fuse. Ground for the switching module will go to the negative bus bar. If everything other than the trolling motor is running through the Yak Attack power switching module, the Blue Sea fuse block seems maybe unnecessary, don't currently have anything else to run through it. I could do an inline fuse and call it good there, and use just a non bussed fuse block for the power leads off the power switching module? The HDS Pro, Active Target 2, S3100, and lights will power through Yak Attack power switch module. Now with regard to fusing those individual power leads off the Yak Attack switching module... Do I simply put inline fuses in place (seems like I can make them fairly water resistant) or work to satisfy the OCD in me and put in a non bussed fuse block? (more appealing organization wise, but likely not as water resistant, although I could go after it with lots of silicone after attaching the leads)
Once I get the batteries in hand, I need to figure out a box or two for them. Ought I try to put them both into 1 box or a separate box for each battery? I'm thinking 2 boxes so I can take only what I'll need that day.
Thanks!
