Trolling motor battery 2- 12v or 1- 24v

[FishNHard]

I plan on putting a Minnkota terrova on my 16ft boat this season and the question i have is about battery's , i plan on going with lithium and was wondering since the TM is a 24v motor do you think its better with 1 24v battery or going with 2 12v battery's

24v will last longer

Interested as well. Always used 2 12s but need to buy new batteries this year. Boats sat for years since having a few young kids lol

I have always used 2 12’s in my bassboat. One of them will be at least 1 year newer than the other. I replace batteries every 1-2 years. I can also take one battery out and use it with my small Jon boat on smaller motor. I have also taken a battery to run an bubbler for my minnows. So its nice having access to numerous 12 v batteries

If you have the room a 24 .

will be a little lighter than 2 12 of the same amp hour .

Batteries should be purchased at the same time when combining them for 24 volt or 36 volt use .

using batteries that are a year older is just ruining the life of the newer battery

Maybe so but I havnt had any problems. One of my batteries is from 2018…it runs a bubbler for days in my minnow tank.

Big difference using an old battery for 12 volt application , but if doing 24 or 36 you want those batteries to be exactly the same .

I can appreciate that. But I ran a new 2023 12v battery and a 2021 12v battery in a 24 v trolling motor system for 8 hr bass tournaments about twice a month last season and always had plenty of juice at the end of each tournament ….in the event I had no juice …(windy conditions/using spot lock a lot) …I have a backup 24v system I can plug into.
