They’re great batteries. I have twelve of them and they’ve been working flawlessly for over a year.

Professor. Thanks for sacrificing life and limb for the review of this battery.

Good demonstration. The Power Queen designers know what their doing when engineering a trolling battery. I can imagine this trolling battery would work really well as a golf cart battery.

It's a trolling motor battery. It's full of foam so it can float when it accidentally gets dumped overboard. A cubic inch of water weighs 0.036 pounds. 13" x 7" x 8.5" = 773.5 cubic inches. 773.5 x 0.036 = 27.86 pounds. This thing displaces almost 28 pounds, yet only weighs 22 pounds. It should float nicely. You may want to test that.

To paraphrase Lord Farquaad, "You may bleed, but that's a risk we're willing to take".

The excessive foam might be to protect the internals from damage when boating, especially when marketed as a trolling motor battery. EVERYTHING in my boat takes a beating when going 30+mph on choppy water.

Awesome! Hobo rules. And yes Power Queen, I'd be sold if you got rid of that foam.

What a great video! I bought one of these last year for my solar power storage build AND to replace the trolling motor battery for my canoe which is now at the bottom of the pond (with some fishing rods too) after an unfortunate incident 😞. So glad I got this and you confirming that I made a good choice! Great price - I bought mine on Amazon on November 27, 2023 for $246.99 . Thank you for taking one (actually a few) for the community. You Rock!!!

The reason they're keeping those so large is because they're ordering off-the-shelf batter cases, which further reduces production cost. A couple pieces of foam is pennies, having a manufacturer make custom fit cases would cost a $100k just for due setup.

Reasons for the foam: -Batteries, boards, and even the temp sensor don't do well from repeated drops that take place from a portable unit. -The foam provides damping for the structural integrity of the outer casing during transport. -Different thermal coefficients and varying temperatures inside and outside the battery would cause cracking. The foam allows for vary expansion and contraction of materials while maintaining a tight fit.

I thought for a second I was watching the wrong channel when you started cutting the battery case apart. LOL

Reason for the size is to keep it at a group 31 sized battery to fit into same trays most 24/36v bass/fishing boats already have in the boats. for the non trolling motor batteries I would agree the extra size is not needed but for bass boats, its ease of replacement for a drop-in swap

That is one helluva price on a very good quality battery with LTCP. After your previous review of their Group 31 sized battery, I bought two of them for my home storage solution. They will actually all work for powering a trolling motor. To answer a couple of the questions you posed in the video; many boats have built-in trays which are designed for Group 31 or 24 sized batteries, and the max draw from most trolling motors (12, 24 or 36 volt) is typically not much more than 50 amps. That's far less than what the starter motor battery in a car or truck will draw.

$239 is insane. One day in the near future we’ll get them below $200. I could imagine that all that foam is intended as protection for rough environments. So using a standard case still makes sense. So about using it as a starter battery. Using two in parallel might do the job. 300ah with 300ah surge. I would thing that different engines need different amounts of power to start them. I have a 50 HP Yannar diesel on my sailboat. These batteries might be able to start that up. But I’m also planning a 400ah housebank, which would have 600ah surge. At a minimum it could be a backup solution to starting the diesel.

This was an AWESOME demonstration! Great job! Thanks for preventing us from having to do it 😂

Hi, you even gave blood for the review! Loving it, showing the way to go. Take care and demurred as you go. M

Most boats have battery trays or battery boxes that use standard size batteries. Southern Florida usually does not go below freezing in the winter for more than a couple of days a year and only for a few hours.

Your dedication is unquestioned !!

I use a lithium ion battery in my motorcycle. It works well because I rarely/never ride in sub freezing temps. The manual actually recommends turning on the headlight to self heat the battery in those conditions. It also works well because it can sit for a whole season without discharging or going bad like a lead acid battery, and it saves weight. It's more expensive, but I've already saved money by not having to replace it. It also has discharge protection with a power reserve, so I don't need to bump start the bike.
