    Lithium battery set up

    I’m wanting to switch to lithiums for my trolling moto I have a 24 volt ultrex 80 lb thrust .. should I go with one 24 volt or 2 12volt linked together like that i have now , also how many amps do you guys think I would need ? Any help would be appreciated…. Trying to get some ideas before I look into buying to gauge what kind of budget I am looking at

    I just did the switch. I like things balanced (at the rear of the boat) so I went with two 12v group 24 100ah. Really no wrong way to go.....

    Go with two 100 amp lithiums in series, that way if you should have one fail you only need to replace 1 battery. I doubt you'll have a failure. Charger setup is simple like you have now. (this is what I run now with a 80# ulterra)

    I just bought the Li Times on a flash sale for under 300 each for the group 31 140ah batteries. Couldn't be happier with them. I did 3 with my 36 volt and just dropped them in bought a new charger and good to go. App is great and the power is amazing. 14 hour practice day standing on the trolling motor on about 9 and the lowest they ever got was 58% and charged in 4 hours.

    Don’t forget about the charger….. has to be a lithium compatible charger…

    Just went 2 x 100ah a few months ago. Get the bluetooth in whatever brand you choose. Well worth it.

    I'm in the single cell crowd.
    I have one 40ah 36v in my 21ft Lund Aluminum boat.
    And one 60ah 36v in my 26ft big center console.

    I don't want the multiple batteries in parallel setup....

    Now that is easy for me to say because I have full redundancy and can pull parts out of either boat should I have a failure....

    24v @ 50Ah is a typical 1 for 1 replacement of two new lead-acid deep cycles. If that much energy worked for you with lead, it will work for you on lithium.

    If you want to increase run time, going to 60Ah or up to 100Ah are the other popular choices. Lots of related battery content on my channel.

    This is what I did for the same reasons, plus I take them out of the boat in the fall and use them in my ice fishing house for powering the forced air furnace and lights.

    I have 24v TM, went with 2 105 amp. Fish a lot of wind, and tidal. Comfort knowing I don't need to worry about my batteries in the 9th hour of the day. Run a 105amp for my Stand alone house too.

    I would go with two. I have always been told if one fails you can throw a regular battery in its place and not ruin your trip.

    I went with two 100Ah LiTimes, so I could use my existing battery trays and so I have the option of pulling one out for kayak use.

    When I made the switch, there were no deals to be had on single 24v batteries. I picked up 2 new Ionic 12v 100ah for $350 ea. Then a few weeks later found a deal on an Ionic 12v 125ah for my cranking/house battery for $400.

    When the time comes, I'll go to one battery for TM 24 or 36v depending on my TM.
    Been fishin' since I was 5 years old...Thanks Grandpa!

    I have a 24v 50ah ionic. I have been happy overall but have had one issue you may want to consider. Typically in a full day of fishing (sometimes with heavy river current) I have about 40% left. Over the weekend I accidentally forgot to charge between trips and ran it to zero. When fully discharged you will have to “wake” the battery and either have a 24v system to jump the battery or a charger capable of waking it. Jumping a 12v is generally no problem but unless you have extra batteries jumping a 24v system is a pain. If you go 24v I would recommend buying the charger that will wake a sleeping battery. I went cheap Amazon charger and now have an ionic charger otw.

    I would also agree that the Bluetooth is worth the extra money.
