Doug, I really appreciate your no fluff style of explaining all of this complicated stuff. I watched 10 different videos and didn't learn squat, watched this video of yours and I'm and running. Thanks for sharing.
Really helpful video, thanks again Doug for some great tips
Thank you! This video is so helpful
Doug very nice job on the video best one yet.
Thanks for the kind words. Glad it could help
Good video. Man it must be hot there where your at. You was sweating down lol.
Excellent
HOLY Shit Doug nice rig!
Doug, Very good information about rigging ones boat. Today, I was seeking material to install a Helix 10. Your video changed my mind about how to rig my electronics. Thank you!
Glad it helped!
Hi Doug, which Exide cranking battery are you running all those graphs/pumps off of?
I have a 31 agm battery from interstate, and it has 5 less reserve capacity than the 27 agm you have listed. I'll have to do more research when I buy my next boat batteries!
That is Exactly why I mentioned this is Group Code don't mean squat...It's what's inside that really matters the most. Glad it could help the next time you buy. Buying by the specs is what really matters.
Doug I'm buying a z21 one battery for gas motor and 3 batterys for minnkota 36 volts I'm going to buy 2 solix 15" screens. Should I hook the fish finders to the starting battery or one of the end trolling motor battery ? Or should I get a extra small 12 volt battery for just for the fish finder ? i would have 4 baterys then on boat. Thanks
Jim
Can you really run six graphs off of one dual purpose battery without draining it too quickly? I have two helix 10s in my boat, looking to add an additional helix 7, and trying to figure out if I need to upgrade my battery
Hi Mr V , Great video , does a solix use more amps then a regular helix , someone told me a solix eats up the battery
SOLIX does require more power to run the advanced features and larger screen but it only requires 5 amp fuse so not much more than HELIX. I run 2 SOLIX & 3 HELIX plus everything else on my boat off a single battery.
Lota wires on that one neg terminal, I think 4 is the max allowed. Maybe use a bus bar?
Minnkota recommends 105 Ah (Amp hour) minimum on the majority of their trolling motors. I understand that Amp hour and Recover Current are NOT interchangeable and some battery manufacturers offer one or the other in the specs. I have read that there is a conversion formula that you can use to convert one to the other and that its typically a hair higher than 2 RC's to 1 Ah. Do you have any information about the difference?
It's Reserve Capacity and Amp Hours both help determine the amount of electricity that can be stored in a battery for use by electronics or in the case of starting batteries how long they can spin the starter. I do not have a conversion chart but might check google search engines lost of good reads on electricity on the internet.
What’s your thoughts on lithium batteries?
How do you connect the tiny power wire to the 10 gauge wire?
How about this. Many people believe in running a separate battery for electronics. So if you have a 36 volt trolling motor system, this means running 5 batteries. 3 trolling motor batteries, 1 starting battery and perhaps it also powers livewell, bilge pump, and all of the factory installed components, and then 1 deep cycle marine electronics battery. Maybe Minn Kota should design a 5 bank charger. I run the MK 345. I have a Lund Rebel XS. I just run my electronics off my starting battery as you do Doug. That's because I have a cabin and I just pull up to the lift when I feel my batteries are getting too drained and then I can easily plug into solar which I leave at my boat lift or plug in my on board charger.
I've never found the need for 5 batteries (1 Only for Electronics) and I run up to 5 units on the boat. But I buy the best Reserve Capacity Battery for the Starting Battery and reduces the need to have an extra battery. That is one of the reasons I did this video is buying the right batteries based on specs will reduce need for added expenses like adding a 5th battery
So I'm getting new boat and it comes with the interstate 31m-agm cranking battery it has 800 cca or 1190 ca which one go by? And 190 rc @ 25 amp. Im going to put 2 helix 12 mega si and 2 helix 10 mega si and 360 on is this going to be good enough battery? Thanks in advance Doug.
Sounds like it could work. I haven't had much personal success with Interstate but they may work. Specs look good.
Doug, I have the Solix 12 chirp/with side imaging and a MinnKota Terrova with the US2 transducer. Do I use the 14 M SIDB Y splitter cable so I can designate which transducer (transom/bow) is operating ?
You do not need the Y Cable unless you want the 2D sonar always from US 2 and the SI & DI from the second transducer. Or I just install the SI transducer and it will do everything you need 2D, SI & DI from the single transducer.
Doug Vahrenberg Thank You
Doug where can I find the Exide batteries. I’ve looked everywhere I can think of in KC area.
I would contact Exide and they can tell you where their local Kansas City Dealers are. Exide also private labels for vendors and they can get you in touch with where you can purchase.
Doug Vahrenberg Custom Truck in KC is a Exide dealer
I've never understood why you must wire graphs directly to your battery, rather than to the master fuse box, which often times protects you with a master power shutoff. If you wire directly to the starting battery, you bypass the master power shutoff, thus opening the human element of forgetting to shut off all graphs in the boat. Can you explain or do a video why it's important to wire directly to the battery vs the boat's supplied fuse panel. Also, how do you handle the master power, truly not powering down all electrical components in your boat? Thanks. Loved this video by the way.
It all depends on the amount of current through that master powerswitch. Plus powering down a unit by cutting power and not using the proper button on the unit can damage the unit and not save settings. Not good improperly powering down unit and not good not providing it sufficient power. Plus you should always fuse the wiring at the battery for the unit so it's protected too.
I have a master power switch on the dash for all other electrical but my fishfinders. For that (helix10) I use the same 10awg wire Doug recommends to an on/off switch then to a buss bar and on to a new fuse panel. The power wire from the helix has a very short distance to travel as the fuse panel is right below the console. Works great!
The way I have mine setup is I have a battery mounted 60 AMP fuse. 6 AWG going to a Blue Sea Systems which has a positive and negative bus. I cut out a hole in my dash and mounted a battery switch. So the positive goes from the battery to that switch and then to the Blue Sea Systems fuse panel. The negative goes straight from the battery to the fuse panel. I have it screwed on the wall under that is the longest distance from my feet just above the floor. So it's basically the same concept as master power. One battery switch turns on the whole circuit that connects to that fuse block.
And yes each of the individual components have 3 AMP fuses to each of them on my Blue Sea Systems fuse block.
@@DougVahrenberg well what do you recommend? I two am running new wire for my bigger helixs, one at the console and one on the bow. Should I run dedicated wire to both straight to the battery? This means four sheilded 10 gauge wires from the battery up to the console and the other two going to the bow? Won't my units drain my battery?
Doug I’m looking at getting a battery solely to power my new Helix 10 mega si g2n. A battery that will get me through a day of drift fishing, spot locking and still maintain 50% battery life by the time I’m back at the marina, any ideas on a battery for this application?
You need to purchase a battery based on the Reserve Capacity that is amount of electricity available for using electronics. May need 2 batteries connected parallel to get the capacity you want and maintain 12 volt.
Doug Vahrenberg
Think I’m going to go with the two battery parallel setup. Think a 2- bank charger will be ok to use with this setup?
You are saying that because you are running several units you use 10 gauge or you run 10ga to each unit. 10 gauge is rated at 30 amps. I am fused at 5 amps? That is 6 times the current carrying capicity than it is fused? I am an electrician and I believe in running bigger wire than needed for voltage drop. I thought mine was over kill with 12 ga wire.
Good video only thing lacking would have been a discussion around interference and what to do about it.
Can you post the name and source for the wire?
Wire for the graphs.
My 2002 boat was rigged with what looks like 18g wire, Just won't work for today's electronics!
Exactly. This is one of the big reasons to make sure your units get a proper power supply. In 2002 we didn't have 9, 10, 12, or 15 inch units with all these technologies.
