I put this on the forum's Boat Maintenance section but suspect I might get better results here....
I recently became the owner of a fishing kayak with a 55 lb thrust trolling motor. Battery that came with it is a Walmart product that is not up to the task. Have done a lot of on line searching and, like everything else, there are myriad choices, some involving a double fistful of shekels.
Any "been there, done that" recommendations? Seems LiFePO4 batteries are the best, but quite a bit more than similar capacity lead acid AGM varieties. Plus, to be charged properly, they need a charger specifically oriented to the litium battery charging protocol.
I wont be needing the battery to last all day, as I am a "casual" fisherman, but also dont want a battery that will leave me stranded and having to paddle home, lol.

If weight is a consideration, LiFePO4 is the way to go. BIG difference.
LiFePO4 stays charged and won't sulfate due to neglect. Always ready to go.
To size battery, take duty cycle x amps x time to get amp hours.
Then overrate by 2 or whatever you feel safe with.
Remember lead acid batteries can only be used to 50% of their amp hour ratings. LiFePO4 to 100%
Be cautious buying LiFePO4 starter batteries with lead acid equivalent amp hour ratings. They inflate the LiFePO4 rating.

Lithium is best for power, longevity and weight. If weight is not an issue then AGM is a good in between. Still heavy but works much better than lead acid. Both lithium and AGM are more expensive but allegedly worth it in the long run. I plan to replace my RV house batteries with AGM when the time comes.

Thanks to you both. Weight may indeed be a factor because we recently moved to Lake Tallassee and currently I have to bring the existing (plain ole heavy lead-acid) battery up a significant hill to recharge it. Thank goodness a UTV came with the property, lol. Our dock has a GFCI outlet on a post at water's edge, but I haven't tried it yet. Guess I should find out if it can be energized.
