Trolling Motor advice needed

[kjfishman]

My 12 volt bow mount trolling motor is getting tired on my 16.5 deep V. Considering upgrading to a 24V bow mount. The problem I have is there isn't room for another 12V battery at the stern. Also have a 12 v transom mount trolling motor. So I can't switch to 24v battery and be able to use the transom mount motor when I need it. I was thinking mounting a 24V 50 AH battery in the bow for the bow mount. Would 50AH give decent run time?

You would need to decide on the trolling motor and see what the draw amps are then you can approximate the run time.

in terms of pure energy capacity, a 24v 50ah lithium will have more capacity than all but the biggest 12v lead battery. It will have more usable capacity for sure. If you’re not using the motor for running spot to spot or holding in river current then it should be fine.

Tracker Classic XL,  16 feet 8 inches Mod V.   Motorguide Tour Pro 24 volt, 82 lb trolling motor.  I have 2 Ionic 12 volt 50 amp hour batteries.  These will equal one 24 volt 50 amp hour.  I have never ran them below 50% in a single day fishing and this would be a long day with a bunch of wind.  I fish 2 or 3 days on a charge sometimes.

I have a 15ft mod-V polar kraft….I have. 12-V 45lb motor guide, bow mount with foot steering, and I use a group-24 deep cycle. Had for a few years now and no problems. I’m on a lake and fish a couple rivers with current, but nothing outrageous.

Ditch both the 12v bow and stern mount TM's and go with a 24v bow mount TM with one single LiFePO4 24v battery. The AH size depends on how long you need to use your TM. I have one electric lake that is 15 minutes from my house that I'd absolutely need 100AH batteries to fish 5+ hours. But on a river I just run and gun on my big motor and use my TM mainly for spotlocking. It never hurts to go with more AH though.
