Battery Test for Canoe or Kayak. Do you really need Lithium? 

😂😂😂 Thanks for the shout out! Great video! I agree that lithium just isn’t there yet in terms of value, especially when AGM is sort of a bridge between old and new tech. My dad has a Gheenoe with 45lb thrust TM and is replacing his optima blue top with a comparable Duracell AGM when the time comes. Loved the on the water test!

Good video. I like your production qualities and you obviously use these batteries in real-world scenarios. You realized the weight penalty that comes with lead-acid batteries, including AGM. You could have purchased a 100AH, "mini", lithium iron-phosphate battery that weighs only 20lbs and gives you very close to 100 amp-hours of real, actual, usable capacity. By comparison, the 35AH AGM battery you demonstrated in this video can only deliver about 50% of its rated capacity, or around 17.5 amp-hours, before the voltage drops too low and it is "dead", meaning it won't run your trolling motor or your fish finder anymore. With that battery chemistry, you better remember to charge it as soon as you get home, because if you forget and leave it that way for 2 weeks...it's a one-way boat anchor. So, you spent $85 dollars to get 17.5AH ($4.85/AH) of usable capacity, with voltage sag and reduced life-cycle count. You could have spent $200 for 95AH ($2.10/AH) of usable capacity, vitually zero voltage sag across the discharge curve, much faster charge times and much higher life-cycle count. Perhaps more to the point, for a canoe or a kayak, you could have bought (or made) a 50AH, lithium iron-phosphate battery, for right around $100. It would weigh 12.5lbs and deliver nearly 3 times as much usable energy, with all of the other advantages already mentioned. The only people buying lead-acid batteries for trolling motors or fishing electronics, these days, are those who do not understand the difference between cost and value. For those uses, lead-acid batteries are a false economy. They are still the better choice for a high-draw cranking battery, though.

Great video! This was a good comparison
