I've been using lithium ion batteries since 09, been through 3 kayaks since then and on my fourth. Still on my original set, Batteries are still going strong. I did pay alot of money for them but i bought them just once and they power all my devices all day and some. Plus they are even lighter and smaller than the lifepo batteries... But the only drawback is you cannot get them wet, luckly i never have yet....
Alot of us have really powerful and expensive fishfinders. Why cheap out on the power source? Having that extra capacity in a smaller lighter package that will probably outlast your kayak is worth it in my opinion.
