Trolling Motor Batteries

Recommended Posts

I know this topic has been posted before (I did a search but couldn't find the exact answer I was looking for) so I apologize for doubling up! But my questions are:

What group size batteries should I get? I believe my trays are set for 27 max, but is it worth it for refitting for group 31?

What brand to get? I've heard Interstates are good, as well as Cabela's AGM batteries.

I don't to take any short-cuts on this, but are there any batteries in or under the $150 class? I know you get what you pay for, but maybe there is a decent cheap alternative out there.

Finally, just to clear this up for myself, I have two batteries up front for the trolling motor, but they are not hooked up directly together. Instead, wires come from the trolling motor and seperately connect to both batteries. This is a 12 volt system, correct?

Thanks for any responses! Again, I know this topic has been covered in the past but looking for a bit more specific answers. Thanks!

Sounds like a 24V system to me. A lot of times the jump is made at the plug. Do you know what model trolling motor you have?

I have heard good things about the Walmart Marine Maxx batteries--they very affordable.

At this point it's not safe to assume it's one system over the other.

It could be a parallel setup at the plug or a series setup at the plug.

You would need to take a look at how the plug is wired to the trolling motor (red wire or orange wire) to get started determining what voltage you have.

Thanks for the replies, I'll check that next time I can get to my boat. How about what size or type of batteries?

You'd get more run time out of 31 series batteries, but unless you're unhappy with the 27 series, I wouldn't go up in size. It's up to you, though. If it were me and a 31 wouldn't fit, I wouldn't take the time/effort/expense to change unless I was really unhappy.

10 yrs.ago I brought a walmart battery for my wifes car. We sold to her niece It lasted a long time. I would say it was one of the better ones I've brought.

I think the size depends on your fishing style / preferences.

The group 27 do a good job, but if you do a lot of running or a lot of time before charging, the 31's will give you extra run time. But, they cost more and weigh more (which in effect cost you more again with burnt fuel)).

What Brand? Interstates are tough to beat... the AGM offer some nice advantages but take a special charger.

I've used several brands of batteries ( Interstate, Die Hard, Batteries Plus Worker's, MnKOta, etc,) but the best batteries I've found is Excide Marine. With heavy use I got 5 years on my last two pushing a Lund ProV 1800 around and sold them with the boat. I'm going on year 3 on my current batteries. These batteries are also reasonably priced.

Walmart batteries? I've heard bad things about them. They are probably made in China.

I've got a Walmart Marine Maxx sitting in my basement and it's clearly made by Exide. I'll take a photo if you don't believe me.

Bought two of the deep cycle marine batteries at WalMart in New Ulm for the fish house. Paid $62.00 each plus $10.00 to dispose of old batteries. Have heard nothing but good reports about them. Incidentally, have heard most all batteries are made by one or two companies in the US.

I have never gotten more than 4 yrs. on a battery weather it was 12 or 24v. Didn't matter what brand of battery. In 25 yrs of fishin. If you listen to Bear facts and Fish tales on Sunday nite. Larry Boilig has said the same thing.

    • Adding a 4th wouldn't do much IMO. The map screen is already too small to be useful when screen is split in 3. I added a Helix 7 G2N to use as a map screen. Networked with other 2 units
    • I could always go and spend more money on an additional unit but some of it is like Floyd said. I have a hard enough time watching one screen. I have the app on my phone. I think that lowrance has the ability to split the screen into 4. I just can't believe I'm the only person who would like to see this but maybe I am. It may not be as big a deal once I get more familiar with the unit. Right now I like to look at all the screens to help discern what it is im seeing on the screen.  I appreciate the input!     
    • Males were on the beds last night on a lake here in the metro. Not my deal, so I let 'em be. Which means I didn't catch much at all compared to last week.   Oh well, be a couple weeks before the summer patterns start happening. Already a hint of cottonwood floating on the water though. *booooo*
    • I would agree with Purple.   Just add an inexpensive unit of your choice for the maps.   You could even use a cheap tablet with the navionics app on it for the mapping, if money was an issue.     You can buy a 7 inch generic (RCA) tablet for around 50 bucks.    A few bucks more gets a holder.    
    • I would just buy a couple different boxes and pattern them with all of the chokes and see what shoots and patterns the best.   Depending on your hunting style a more open choke if the birds will be closer. I will normally have the tighter choke as the way I hunt the birds will be farther away but I also shoot an O/U and tend to let the birds get out a ways before I shoot. So an IC/MOD may be a good choice also. But like I said I would pattern the gun with each and different loads just to get a feel for it and whats best for her confidence.   I shoot steel all the time and I tend to shoot 4 shot and late season even 2 shot to deal with late season hearty winter birds.    Welcome to HSO!
    • It might be better to buy a small second unit and link them.    My guess is what you want is not something enough people want to justify implementing.   Personally I have a hard enough time watching a bobber.
    • Welcome to the Forum.  What brand gun is it? Would help to pick choke tubes out.  Size 6 shot should do the trick, but I'm sure more folks will chime in here. 
    • I upgraded my electronics this year to a Humminbird Helix 10. I love it so far with the exception of not being able to split the screen into 4 separate screens. The max that you can do is 3. I would really like to be able to have the map, sonar, down imaging, and side imaging on the screen at the same time while trolling. I emailed tech support and they said it's not something that is an option at this time. Right now when I'm fishing I switch back and forth between map, sonar, and DI and sonar, DI, and SI. Is there anyone else that thinks this should be an option? I don't know see why you can't customize the screen to show whichever features you prefer instead of only using the preloaded options that Humminbird decided on. I have thought about emailing the company weekly asking if they have that ability yet but wanted to see if anyone else thinks it should be an option. 
    • I just purchased a used 20 gauge for my 14 year old daughter. I hunt mostly state land for pheasants. It is a 2 3/4 auto with interchangeable chokes. What size steel shot and choke tube would you recomend for her?
    • I just got back from a work trip to MI. I could not believe the difference in ground cover. We traveled all the way from Dearborn back to Bemidji heading through the U.P.  Most of MI had very little ground cover but WI was flush, green everywhere! I only got to check a few spots at rest areas but I never saw a thing. The ground was dry at most spots on the way home. I'm gonna go hit my spot tomorrow, hopefully it hasn't been picked yet!
