Batteries for trolling motor.

[GotPumP]

I just bought a new trolling motor it is a 71lb thrust 24v. I'm looking for a fairly good set of batteries that will last the day that aren't going to cost me a ton of money.

Any suggestions? I see someone posted the Kirkland Deep Cycle Marine's from Costco are very affordable. Would this be a good idea or do they lose their charge quickly?

Thanks again,

I have the minn kota power drive v2 74lbs thrust in a 24 volt set up and I bought the marine batteries from canadian tire. This will be the 3rd full season and I had a partial season the first year and they still charge full and run for a very long time on my set up. I also was running my 12 volt back trolling motor, sat. radio, and one of my fish finders off of these batteries and I could easily get a full day out of them. They were a pretty good price to. I am pretty sure they were right around the $100 mark a piece. If my buddy decides he wants to keep his fancy batteries instead of hooking me up with them then I will also be getting a couple more to rewire my whole boats electrical to except the trolling motors.

I have one of the Costco batteries, mine has the dark blue label and it was the one with the most amp hours. Its a marine deepcycle/starting.

I can run it for probably 6 hours with my 30lbs thrust

I have 2 of these batteries in my rv. best bet would be the ones mentioned here. I think they're 115 AH. Group 27. I will be adding 2 new ones to my boat this spring for my Minn Kota.

I think Costco's price was $109 each with no battery tax added on. They don't stock the deep cycle in the winter so you'll have to wait till spring to set up your rig.

The only ones better would be the Optima sealed performance batteries. Alot more money though.

Wally world has Energizer brand deep cycle batt.In the spring there on sale for$100 there a group 27 (55lbs) and they have 180 amp/hrs.

X2 Tungsten; they are what I run - glad i saved the money so far
cheers

[horsetrader]

I run the crapy tire marine for my bow mount 24v can run all day in around the islands no problem their on to their 3rd season

x3. These are well known for being the best bang for the buck and have very good run time. Else you need high end trogan's or something but the walmart ones run great. I have a 18.5 foot heavy azz fiberglass sport boat and have a 70 lb minn kota 24V for nearly two full days of constant use.

Thanks!

[GotPumP]

I don't see an energizer group 27. I do see everstart which is the same??

Part number 27dc-850n

amp hours 120
reserve 180

is this the batteries mentioned above?

[nicemustang]

Deep cycle?

[GotPumP]

Ya I but this is the Walmart House brand so... ya. Anyone used these before?

Yes i just had a look at mine
thanks for the correction they are 120amp/hr not 180.

Remember these are not true deep cycle batteries,i wouldn't be surprised if all these hybrid deep cycles were all made at the same place.

The first battery i bought some 10 years ago i used for my trolling motor and i ran it dead almost all the time and since i was away from any chargers they sat dead for a few days before i was able to recharge them.This battery only lasted 1.5 seasons.
I now have 5 of them and only discharge them to about 70% before i recharge i now have a small gen set to do this.So far the battery that was purchased in 2006 is still going strong lets hope the rest do the same.

[nicemustang]

I can't confirm, mine are in my boat under lots of snow and I'm not going go out and look.

[GotPumP]

Tungsten are they Everstart or Energizer brand?

[seahawkfisher]

lookin at mine right now; the # is warn a bit: 27DC4sumthin50N
180 reserve
120 amp hrs
850 CCA
yup, it's an Energizer; and it's a big, heavy bast@rd - i believe the 27 in the model number designates group 27, no?
cheers

energizer.

energizer.

not sure of the difference,i looked at the walmart web site and they had nothing on the deep cycles from energizer.
I read somewhere maybe on here but for dc batteries the heavier the better meaning larger plates.

Almost.

Thinner plates, better purity of lead, and more of them.

The ultimate trolling setup? 4 deepcycle 6V Batteries Wire 2 pairs in parallel, then the 2 joined pairs in series. (golf cart batteries)



Effectively if the 6V's are 300CCa's and 250Reserve capacity, you will end up with a 12volt battery with 1200CCa's and 1000 Reserve Capacity.

You will be able to run for a long long time with that.

Edit I see you have a 24V wire all in series

With that kind of setup wouldn't i need a 4 bank charger? Also would their be any weight difference? How many more hours of use would you get running 4x6v vs 2x12v?

This is my first boat and I would like to get the best setup I can and do it right the first time.

Thanks guys.

connect all the + signs to the - signs. Then the outer plus and minus signs of the outside 2 batteries to your motor.

How many more hours? Look at the Reserve Capacity and Cranking amps of the 6V batteries, and add them up compared to 2 12V batteries.
ESR (equivalent series resistance) issues aside (basically internal battery resistance) is less on the 6V setup. Faster charging and less internal leakage

For size, it is easier to place 4 6v batteries than find room for 2- 12v batteries.

What it boils down to is cost. 4 6v batteries will cost about 20-25% more than 2-12v batteries. But in Optimas, your 12V red top RC is 100 per battery. 200 total for a 24V system. At the same 800CCAs per battery.

But in their 6V setup, you still have 100 RC per battery X4. 400 RC's!
while still maintaining the same 800 CCAs


To charge, simply disconnect batteries, and charge by pairs using a standard 12V charger (very handy if you do not want to invest in a 24V charger!)

I would look into an Odyssey or a Optima system for a boat. I use them in my RV in 6V and 12V and they are great.

One side bennie of 6V. If one battery starts to go bad, just replace one 6V instead of a whole 12V battery :)

Pay more up front, with a lot more economy in the long run.

For the record, I use 1-12V Optima blue for my trap launcher. I knew better. I should have waited for the 2-6V batteries.:angry3:

Charge all 4 batteries without having to disconnect it?

Definately yes!

your charger will only see the 24v load on a series connection. So you would set up the charger in single bank 24v configuration :)

On edit: If you decide to go with 4-6V AGM batteries in series, I would call the manufacturer prior to buying the batteries or the charger to make sure that the amperage the charger is pushing will be enough out of a single bank to bring the batteries up to their fully rated capacity.

AGM batteries are more robust than Sealed lead acid but their charging rates are different.

AGM's are more linear than SLA's Batteries I can give advice on, the charger I would call the manufacturer on to ensure it is compatible with the batteries.

[GotPumP]

Thanks a lot for all your help guys

[Tungsten,]

let us no what you end up getting and how you hook it up.

I was also interested in this kind of set up a few years back but ended up going the 12V way.

If i remember the 6V were about $140 ea. and about 70lbs ea.Also the cable that you run from the batts. to the plug will have to be able to handle the voltage.

I never did look into a 24V charger and how long it would take to fully charge the 4 batts.

Thanks in advance.
