Going through the wiring on my new to me boat. The accessories are hooked up to the starting battery including a Helix 9. I thought I might use my separate little lithium 15ah battery I have for the Helix but I'm not even sure where the wiring is. On my old little boat I had the wiring coming straight to my little battery but these must be group together somewhere. Is this starting battery enough to run accessories?Attachment 481645Attachment 481646

I use mine to run the Helix, lights, and pumps. All the lights on the boat are LEDs. If I become concerned I fire up the 4 stroke Mercury and let her run for a while.
I run 2 graphs, led lights and pumps as well on mine with no issues but it’s a group 31 battery. I’m like Jack and run my main motor iffn I get concerned.
I don't think the group 24 will work out to good at all.
That might depend on what size motor he has on his boat. My 90hp Merc 2strk will usually keep my Group 24 starting battery pretty close to fully charged, just from the idling I do at the ramp & running around the lake. And that's even when I don't run more than a couple of miles away from the ramp. My big motor, the guages, and the livewell pump are the only things run by that battery, though, as I do not have a depth finder at the console. My LS has it's own separate battery & the Hook 7 runs on the trolling motor battery (68ah AGM).Quote:

Sorry, 10point, but I've never had a motor smaller than 50hp .... BUT, on that boat, I only had one battery running everything. I just don't remember what size battery I had back then - 1970's (but it was likely a Group 27 Deep Cycle).Quote:

I have a cheap 24 series battery in my boat for cranking my 90 hp carburated motor an have both livewell pumps, running lights, and Helix 9 attached to this battery. Never had a problem.
I would cut the rings off and crimp on the right connectors. They should be available at your local auto store or walmart.
If it were me I'd run as it is and fish a few times to see if there were any voltage issues at the end of the day.Quote:

I have a voltage meter and It is currently reading 12.45. Not sure at what point I get concerned.Quote:

You can add voltage to the readouts on the screen.Quote:

I switched all of my electronics (2 93sv and livescope) to their own battery. Running all of that plus the pumps off the starting batter was becoming a problem if I fish a long day. Running the starting battery down to where it would barely crank the engine. Also, live scope needs at least 12 volts to function properly. Otherwise, the transducer loses connection every few minutes. Not sure what all your running but a 15ah battery will run 1 graph for about 6-7 hours. Reducing by half for every additional graph. Livescope draws about twice as many amps as a single graph. So 15ah would run my set up for about 2 hours. You may not be running that much so you might be fine.
Mainly would just be running the humminbird on it. I've ran my Garmin 93sv on that battery and it never ran out.Quote:

I have a 60HP 4 stroke and used to run a 27 series battery. I had lights, live and bilge pumps plus 2 Low HDS units on it. At the end of the day it was getting to be too much. I switched to a 29 series and haven't had any more problems.
I like the idea of that noco jump starter regardless of what size battery you're using.
