Thanks for the video and review! Do you expect to have a new discount code for PQ?

[@mikemcguire5859]

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

[@worldfamouspopcorn19]

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

[@ScottDLR]

I did a ton of research before buying 4 of them and I've been nothing but pleased.

[@mickeybrumfield764]

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.

[@heathenshaunt681]

Not designed for golf carts it's on pretty much all their battery pages I saw so far would nit be surprised if it needs a bigger bms to go there

[@markmiller2131]

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.

[@aantosca]

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!!!

[@carlhilton9506]

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

[@searlearnold2867]

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

[@jasonbroom7147]

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.

[@ZF0317]

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.

[@savvyshopper784]

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.

[@andrewvickers4487]

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

[@davidjernigan8161]

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.

[@Sylvan_dB]

Yes, this. Unless they can make them 1/2 size to fit two in a standard space, they would also need to sell spacers to allow fitting the smaller battery in a standard space!

[@LordFalconsword]

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.

[@HOBOTECH]

They already offer a "mini" 100Ah battery in a smaller case. Why not use that case?

[@stedyone1090]

@HOBOTECH For some consumers size matters. Lol 😆

[@RaconteurMan]

@hobotech my hobohobo My guess on the foam would be to: a) provide some protection from extreme temperatures with added insulation 2) provide drop protection and impact damage resistance for the batteries' intended-use environments C) add a "perceived value" to the end-use consumer. IKUKWIMR, who wants a little dinky battery when they're shopping for 'trolling power!'?

[@TheCornucopiaProject-bd5jk]

$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.

[@HOBOTECH]

$229 with code ...

[@markeh1971]

Hi, might be easier to keep a lead acid battery just for starting the engine. Easy to get high loads as the compression builds on each cycle of the engine and a small lead acid battery is cheap and should last years! Take care M.

[@TheCornucopiaProject-bd5jk]

@@markeh1971 it’s cheap, yes. But so are LFPs now. And LFPs should last longer as well. But even if lead acid is around for decades, having a house bank of LFPs that can fill in in case of emergency is a good strategy.

[@davelamont]

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

[@thedownwardmachine]

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.

[@carlhilton9506]

This was an AWESOME demonstration! Great job! Thanks for preventing us from having to do it 😂 I recently bought some “Lomrige” 200AH lithium iron phosphate 4 batteries from Amazon the case closely resembles my purchase (less the size of course)

[@stedyone1090]

Just got 2 of them. Installing them on my boat today with a Li Time balancer.. Hey now That's right ✅️ 😮

[@mats77]

Your dedication is unquestioned !!

[@keithtarnowsky7112]

Boat batteries follow car batteries, they most commonly use battery boxes sized for group 24 or group 27 so that may be why they make the battery cases those sizes.

[@Robert-Wilson]

I was going to say something to the same affect. My mobility scooter uses 2 12 volt 75 AH group 24 batteries. I’d love to upgrade them to lithium iron phosphate to get longer range.

[@markeh1971]

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

[@cherriemckinstry131]

I always learn alot when im here.

[@ralphsmith8350]

VERY good . thanks!

[@clarencewiles963]

Thumbs up 👍 this is way better than I thought

[@spockmcoyissmart961]

I have 4 Power Queen; tips for charging new: I have 4 in series in my system. charge each individually. Move charger to 2nd battery, charge it. Once all 4 have been charged individually, remove the charger and place all 4 in parallel. Leave alone for several days. This is the proper way to equalize all batteries ready for your system.

[@Sylvan_dB]

Almost. But it is better to also use the charger with the parallel batteries. And if the starting voltage is within 0.1volt max delta, then just connect them all in parallel to begin with and start charging. (0.1volt delta, over a battery internal resistance of 20milliohm, means 5amp will flow - this is fine. Even 10milliohm or 0.2volt is fine but I prefer to be more conservative and when you are connecting more than 2 in parallel you need to be conservative.) And if using them in series, once a year or so disconnect them all and do the balancing again. Or using a series balancer (LiTime and others exist) to maintain balance. Otherwise over time the slight differences add up between the 12v blocks in series just like they do for individual cells in series.

[@spockmcoyissmart961]

@@Sylvan_dB I went by power queen instructions. I understand the internal resistance/measuring, but most people here couldn't do that. What PQ recommends is a simpler method for those people. Of course, people have to buy the correct charger for their Lifepo too and don't use an old lead acid trickle charger.

[@anthonymarino4260]

well done

[@JD-ft2lr]

Thanks for the battrry review! But i also appreciate the added info regarding charging, etc. As for starting.... if this battery is used in a boat for electric trolling motor, seems it could be used as backup starting for outboard motors. Most fishing boats have both motors with house batt used for everthing except trolling motor. Having this trolling motor batt on a switch or using jumpers one could possibly use it as backup to start the main motor. Size of outboard and how long it cranks may become an issue i suspect.

[@pdieppa]

Great intro sfx!

[@travelwithherandI]

Great video! I am purchasing 2 of these based on your test. Thank you! I am running them in parallel in my small camper for 200ah of power. What charger do you recommend? Should I charge them individually or can I hook it directly to the bus bars? Thanks for any help!

[@davidjones1393]

THKS

[@ckelley6940]

Great video,information was very well stated. You sounded as if you have a cold or allergies effecting you.If so take care Sir.

[@brownnoise357]

First thought I had on the Case size and foam inside it tbh, was them providing critical protection against destructive Cell Damage? That they have it that way, pretty much guarantees that I’ll be a future Customer frankly. Cells next to the walls of a Case? I’m walking by with a firm grip on my wallet. Great Review. Best Wishes. Bob in Wales.🤔🌟🌟🌟👍🏴󠁧󠁢󠁷󠁬󠁳󠁿🇬🇧

[@EfficientRVer]

When it comes to LiFePO4 batteries, energy per unit volume is about the most important factor for me. I WILL NOT buy a bloated battery where half the case is filled with foam. I love my mini 100Ah for car camping. Space is a very precious thing. They really do need to stick more cells in there to up the capacity, or put it in a smaller case.

[@sellC1964]

Love the review of the battery. I wonder, however, with low temp cutoff, won't that damage any solar charge controller its connected to?

[@2hotscottpro]

All that foam is nutz!

[@-_Raven]

Really like your videos and was wondering if you could do a video on the settings for victron charge controller for lithium ion batteries and lithium iron phosphate batteries cheers keep up the good work

[@HOBOTECH]

Victron has a lithium setting. Use that or flooded lead acid. Battery BMS handles charging.

[@maxoverridemax]

Fome? Maybe it's for protection. You'd have to stab pretty deep inside the battery in order to penetrate the cell. Thank you but like an outer bulkhead.

[@STB-jh7od]

Regarding the size of the battery case, I wonder if it's a logistics issue, buying the same case for all their battery products. just a thought.

[@user-if6jv6ws7o]

Isn't those dimensions for a group 31?

[@stuartstuart866]

I’d rather see more cells stuffed into the existing battery case, than a smaller case. I already have the space in my RV for the bigger battery box, but more capacity would be nice.

[@landi6282]

Could it be used for an ebike

[@jeremymcauliff8485]

Do these batteries require a special charger? I already have an onboard Minn Kota MK 460 charger for my boat. It does have selectable modes for gel, lead acid and AGM batteries.

[@zgomez68]

You need one specifically for lithium batteries. If your charger doesn't support lifepo4 then it won't charge lifepo4

[@HOBOTECH]

As said in the video, you can use any charger that outputs 14.4-14.6v. Doesn't need a lithium setting!

[@ralphsmith8350]

They could make an inner battery with standard terminals sit inside a removable standard case, but separable for those who want the smaller size.

[@Sylvan_dB]

Sounds expensive. How about the smaller case, and optional dummy spacers for those that need to fit in a standard battery hold down.

[@charlesurrea1451]

I've been looking at solar fired security. A lot of them require these damn SIM cards which is a cost I really don't want to incur

[@tinkering123]

My testing to run my 1500w microwave off 100ah AGM. 1 battery was able to run it (140 amp pull) for about 60 seconds. So like any good fool I bought another. Speculation 2 minutes??

[@JD-ft2lr]

LiTime has a small 100ah batt.

[@Snerdles]

What's the difference between their regular model, trolling model, and premium model?

[@stuartstuart866]

For this particular battery, Tom mentioned a better BMS and cut off recovery time. He also mentioned water resistance at the beginning of the video.

[@michlardot2215]

Can I use this battery for off grid ? Like running a fridge ?

[@Sylvan_dB]

Sure. You might be able to find a cheaper alternative without some of the features like cold weather shut off if your battery will be kept at "room temperature."

[@HOBOTECH]

Yes, of course. I said in the video it works great as a house or solar battery.

[@sciologist]

Need results on Over Voltage Charging Protection. Will the battery shut down on Over Voltage Charging?

[@HOBOTECH]

The BMS of course shuts off charging when it reaches 14.6v. There would be no way to charge the battery to full if it didn't work.

[@sciologist]

@@HOBOTECH Have you ever tested it?

[@HOBOTECH]

Read again .... "There would be no way to charge the battery to full if it didn't work."

[@johndrenning5453]

Pretty new to all of this and have a couple questions. Would a Power Queen 200Ah or 300Ah be a drop in replacement for the lead acid battery in my travel trailer? Will it charge when hooked up to 30amp shore power like my lead acid battery? Does it charge from my tow vehicle while driving?

[@HOBOTECH]

The battery acts like a lead acid and will do all the same things.
