Trolling motor batterie

[Retriever]

Hi guys.... before I ask... I’ve read all the previous posts about options for trolling motor batteries however nothing recent and I’m looking for all the help I can get.

Currently I have a 24 volt set up, batteries are 115 ah with 180 reserve...

First question... is the above batteries generally enough for you guys trolling all day, using it as auto pilot when trolling etc?

I found I was running out of juice quicker then I wanted...and they need replacing

What r u guys running spec wise for your 24 volt set ups and the obvious question... price and location...

Thanks!!!

First get your batteries load tested, if you need to replace buy biggest group size that will fit and charge as soon as you get home. My .02

Rule #0 the motor should have digital maximizer built in

Rule #1 charge as soon as you get home or you will buy lots of lead acid batteries.

Rule #2 use AGM type batteries​

​

Rule #3 use a smart charger powerful enough to put back the juice, my favorite:

MotoMaster Eliminator Intelligent Battery Charger, 75/25/12/4A ​

Rule # 4 use trolling motors that are 24V or 36V​

​

​

Rule #5 never forget rule #1

I just bought 2 Interstate SRM-31 Marine deep cycle batteries from North Erie Marina for $150 each for my new Motorguide Xi3 24V/70 lb. trolling motor. They have 675 CCA with 210 reserve capacity @25 amps and I use a Quest 8 amp dual bank battery charger.

I dont like rule 2 couple years ago I went looking for a battery I wanted a big agm after reading some stuff online about how great they were. Well talked to two mechanics that told me to avoid Agm batteries they have a much higher fail rate than the regular deep cycle not to mention diffrent chargers and the extra cost.

Here are the full specs including amp hours. Also a chart showing a 100 amp battery to estimate running time.

Interstate SRM-31 Marine Deep Cycle
Group Size: 31DC
Cold Cranking Amps: 675
Cranking Amps: 845
Reserve Capacity Min @ 25 amps: 210
Amp Hours: 98
Length: 13 in.
Width: 6 11/16 in.
Height: 9 5/8 in.
Weight: 59.7 lbs.
Volts: 12

100 amp hour rated battery / 20 amp draw =

5 hour run time​

That’s exactly the info I need! Thank you so much... so for the price I don’t think I’ve found anything better then what north Erie marine has... anyone care to correct me?

I found nobody that can match a high quality battery like that for the price. I have used Interstate batteries for over 20 years in my boat with excellent results. Just to let you know @Retriever NEM doesn't stock that size but the truck comes every Thurs. and Sam will look after you. Here's NEM's email so all you need to do is ask her to take the number of batteries off the truck for you then pick them up. There's also a core charge of $16 if you don't have a battery for exchange.

Check out great northern battery in Hamilton. I picked up 2 100 amp hour agm’s for about $300. Sometimes you have to wait for a shipment of seconds (visual defect only) they get in 3 different sizes . I also am running minkota on-board charger. Only used them for 6 weeks but at this price point how can you go wrong.

I buy Costco marine batteries for boat and RV. The 27DC size is rated at 120 amp-hours. Just like the 98 amp-hour Interstate battery listed above, these are not true deep cycle (they are a hybrid -- you can tell b/c they list CCA) but for the cost and the output they're hard to beat. Plus Costco's return policy is excellent. These Kirkland Signature brand batteries used to be Johnson Controls, not sure if they still are.

I have an 18 ft fiberglass with a 24v 80lb-ft trolling motor and I troll all day on it and have never had the batteries go below 60%. Used to run my tent trailer's lights and water pump off them as well with great results.

Sorry @Retriever I just realized I mistyped, the amp hours on the Interstate should be 98 not 198.

 

[Retriever]

Hahaha no worries I got excited for a minute I would be trolling for days with those

Rule# 6
Make sure you are heavy enough cable between the batteries and the motor
I switch to 4 gauge wire and made a huge difference

Yes I had the same problem ,factory wiring was to small of gauge put new 4 gauge made a huge difference
Also I installed a 24 volt reset able breaker between lead and trolling motor, it's a good idea if you fish heavy weeds aria for largemouth bass the extra strain on the trolling motor can heat up the system
Love the minnkota inboard smart charger system got two in my boat
