Trolling battery?

I went crankbait trolling today. First time at 1.6 mph. Battery got low after 2 hrs.
Single battery from Walmart
4 Year’s old
17’ G3 Aluminum boat w 75 hp

Thanks

That's a sizeable boat to be pulling with just one 12 volt battery, is the TM a 55# thrust? You can run two 12 volts batteries in parallel to give you more trolling time, best to be the same group size battery, brand and age. Also, the larger the group size the better, I would probably go with at least group 29's or better yet 31's if you got room for them. Or if your serious about pulling cranks may even look to going up to a 24 volt TM in the future, I had a 24volt Ultrex on a 16' G3 40HP running on two Exide 31's and could troll for up to 10 hours straight and your boat is bigger than that.

battery isn't the problem. Your trolling motor is underpowered for your boat. If you're going to be trolling, a 24v motor should be a minimum.

I’m unlikely to drop the bucks for a new TM, XI5 , so what’s my best option?

What size battery?

I have a group 29 and 2 hours of pulling around my 14' Alumacraft will have it pretty low.

Got 18 foot boat and use mnn Kota 55 and 2 31 series batteries. Got switch where I can run battery #1 or battery #2 or both......never had a problem......but don’t pull crank baits but believe I could. My thoughts

If TM is out of the equation, then you need more battery.
Best option, 2 gruop 31s.
Good option, 2 group 29s.
Okay option, 2 group 27s.
1/2 day options is 1 group 31 battery.

I run a 18 ft F&F flatbottom with 90 hp tiller. I can run all day on a US Battery (golf cart). They will do the job!! I can push cranks till i give out and have battery left, just an option since a TM in not.

Do as snubby suggested except if i was gonna have 2 12volt batteries i would use quick disconnects.Buy a trolling plate and run big motor and use trolling motor to steer

I have an Alumacraft Competitor 165, it weighs 1,500 lbs wet, rigged with a Minn Kota Power Drive 55 lb. thrust and I pilot... It is powered by 2- Group 31 AGM Batts in series. I can run ALL DAY, and still have plenty of charge left. They are Cabelas labled.
I pretty much troll with the trolling motor exclusively, only time I use the big motor is when I am trolling into a 20 mph head wind. Then I use them both because I use the big motor as the slave motor, then also I use the I pilot with the cruise control to steer, and maintain the right speed I want to troll. Normally I am not in that much wind, so I only use the trolling motor and I really like the I pilot to troll so I can do so with out having to man the helm. Even if you don't have a power drive the minn kota 55 lb thrust with Maximizer will do the same.
If you have a minn kota 55 lb. thrust trolling motor you can invest in at least 1 group 31 AGM Battery and be able to go for 4 to 6 hours in 5 to 10 mph winds. I have done it regularly before having 2 AGM batts.
Hope this helps.
