Best Battery for Trolling Motor
Hey guys, I’m running a Minn Kota 112 lb 36 volt Ulterra on my Nitro Z-21. I crappie fish a lot pulling cranks. I currently am running three Interstate Group 29s. I’m tired of the Interstate batteries going bad on me 2-3 months after the 12 month warranty runs out. I’m running an X2 group 31 dual purpose for my cranking battery. Ok so my question is which battery is the best option to allow me to troll constantly for an all day fishing trip. Thanks for your input. I’m ready to bite the bullet and get three quality batteries that will last a long time. Thanks again.
6 volt golf cart vs 12 volt
I ran 2 12 volt deep cycle (27s) in parallel in my motor home. These were for running all 12 volt accessories plus TVs on inverters. It had a totally separate battery for cranking and running the engine.
I attended a technical seminar at an RV rally on house batteries and run life.
Turns out I bought 2 6 volt golf cart type batteries and ran in series for 12 volt house power.
To compare reserve power:
With the 2 12 volt ones,after running lights, TV and ceiling and exhaust fans all night, i had about 50% battery life the next morning.
With the 2 6 volt batteries
I had about 85% left the next morning. The batteries were a couple inches taller so I had to extend the tie downs but length and width were identical.
I don't remember the exact number but the technician. showed me the spec on reserve capacity on the 6 vs 12 volt and it was darn near double the reserve amps.
Bottom line the price was almost identical on the 6 vs 12 but the run time was about 3X for the 6 Volts.
Incidentally the seminar was hosted by Interstate Battery which is what I was running. The 6 volts were also Interstates.
