“Sometimes they look really cool on the outside and they’re awful on the inside.” Just like people

Thank you for checking these batteries & letting us know what is junk.

Will, after all these years of watching you grow into the best expert on lithium styled batteries and solar systems from small 12V systems to massive 48V ones, there is no other one who knows solar components and tests them to the depth that you do. I continue to watch your videos just to see the next exciting thing that you come up with. You have helped more people learn how to build a solar system than anyone else in this industry and what you do for the DIYer is has gone far beyond most people's gratitude, including mine.

Will, your battery teardowns are invaluable in both steering us away from deficiently manufactured products, and in holding substandard manufacturers accountable to improve their manufacturing processes. You are providing information that is otherwise unobtainable to us consumers. You also educate us on the technical aspects of electrical systems. Thank you very much.

Well, I finally went lithium. My LI TIME 100 amp came today. I thought this video was going to make me regret the purchase. Thankfully it didn't, but instead confirmed I made the correct decision thanks to you. I didn't get one with low temp sensor. I just won't be using it in the cold. But I will probable buid an insulated box for it. Thanks Again Will.

!!!THIS!!! ..... This is one of the MANY things I REALLY like about Mr. Prowse! .... If something SUCKS, he WILL call 'em out and let everyone know!..... If something is AWESOME, he WILL let everyone know also! .... I wanna be Will Prowse when I grow up!

Thanks Will for all the information over the years. I finally finished my 800 Watt NewPowa (on the shed out back) system in via 8 gauge wire to an EPEver 40 amp MPPT charge controller feeding two SOK 100 amp hour batteries to a Gowise 1500 watt inverter. The system has been powering my 10 foot chest freezer for weeks now. Oh, I bought your book and actually read it! Top shelf!

...purchased 12 Vatrer, was relieved after your breakdown.

Great Video… you had me cracking up…. “Ehhh… What is that?”😂😂. I agree with the teardowns. Some night see it as a waste, but as you clearly show you just can’t judge the battery by looks and capacity. Still the best solar channel on KZfaq! Thank you for all you do!

Thank you for your work and help. Most people are so sick of cheap crap thats overpriced.

Yes! Back to basics! The battery manufacturers probably think they can put out sub standard units again because Prowse doesn't seem to be ripping them apart anymore! Knowing what to avoid till the end of time! 😂

Thanks for going back to the 12v affordable review. I appreciate it.

I LOVE that you rip these open. Just told the wife that if I were to buy some new lithium batteries, from an unknown company, if you don't cover it and don't rate it well, I absolutely would NOT buy it.

I helped a fiend put in solar and lithium battery with Renogy inverter and MPPT in his Class C motorhome. So far, so good. He got the Vartrer 460 amp hour 12 volt battery. It had a metal case, external on/off push button, lifting handles, and looked excellent from the outside. Screws held the metal case together. For $1400 it better be good!

I remember cringing the whole time you took the cutter and went to town on that first BattleBorn battery years ago now. Little did we know then how helpful that would eventually be, especially as all these cheapies flood the market. 👍

"This says dedicated and professional, sure pal" got me. 🤣

Excellent -- I love your teardown videos. Suggestion: From the two good ones in this round-up, get the 200 and/or 300ah versions and see if they have the same quality.

I take your advice on solar for years,always make it easy to understand and your comparisons/reviews are great.

It was fun to watch how much you enjoyed watching taking the batteries apart.

thanks for doing all those tear downs, very nice to see

I have the self heating version of that Vatrer and it was the cheapest self heating battery I could find. Seems pretty good so far. Being able to connect to the BMS with the JBD app is great. I actually replaced the 12v battery in my 2006 Mercury Mariner Hybrid with the 50ah Vatrer low temp cutoff battery and when it got down to 10F last week it did just fine. I have a 100W solar panel on the roof to keep it topped up because it is a backup vehicle.

I recently bought and (unfortunately) repaired a 12v 100Ah LiFePO4 battery which arrived with low voltage, which I eventually tore down to find the bus bar between cells 1 and 2 had come unattached during shipping. Amusingly said battery had threads in the battery terminals and holes in said bus bar to actually bolt the bus bars in but were welded on instead... Really like this video showing some of the gotcha's of these batteries, I think the thing that irritated me about the whole situation was the seller in question said my charger was at fault 😬

I use Power queen 👸 batteries I have been using it now for over two years and some months, still maintaining the same capacity that was rated for

We've come a long way from the 18650 rigs.

Thank you so much,Will. I was just looking into purchasing the two worst ones you just tore down, now I know better and I really appreciate it!

copper plated steel wire / copper plated aluminum wire I'm sure you're finding units with undersized conductors, but have you given thought to checking the quality of the wire itself. I recently found that some of my test leads were made of steel plated copper this inexpensive battery system could lead to devastating failures.

thank you for protecting us. we regular-joe consumers would have no idea about this stuff and i think those guys know it and try to take advantage. you perform an incredible service. thanks and keep up the good work.

Absolutely love these turn down videos I am so glad you do them to help inform the public.

Your videos are BEST of it's kind on youtube!

Thanks for posting this video.hello from Scotland

I love your honesty and your reviews on all pieces of equipment that come through your hands. I hope that the companies appreciate your reviews.

Been waiting for a updated showdown, thanks for doing this yet again!

Hahahahaha I was laughing for most of that video, Thank you I needed that. Lol 😂😂😂

Good Job ... Thanks for your investigative research. None of us could do that teardown

This video was fun hahaha. No Vatrers though, too many problems/QC Issues and their staff not knowing how their own product works. And OMFG that solder on the Bunfloe wtf never seen anything like it. Regarding the Sokerty, it's not even clear to me what they're selling. What is a "LifePo4" battery? Never heard of it. Seriously, if you're going to sell it, type it correctly. Lastly, I've had trouble testing temp sensors with ice. I always end up getting it around 0-2C and it's difficult to pull off those last few degrees (at least for me) and is why I always use the computer duster. That, and some end up being set for -5C. Anyway, sorry for a long response but this one was too funny! I've turned away so many just because I'm tired of looking at the 12V 100Ah's - maybe that was a mistake, missing out on entertainment LOL.

Great teardown video. It's a good refresher for "No Safety, Know Pain. Know Safety, No Pain” and definitely wouldn't hurt to see these more often.

I needed a battery for my Suburban camper, and recently bought an SOK 12V/100aH battery with the Bluetooth option. It cost me a little extra, but it looks like I made a good choice based on what I'm seeing in your battery tear-down videos.

Glad to see you back in my algorithim.!!! loving my skoolie solar setup that i tackled with your advice.

Most of the cost building it was paying for the solder.

I been waiting for budget battery review on this channel a long time..... can't thank you enough for this video

That's not big globs of solder on those batteries, that's what my welds look like. Nothing wrong with them 😅

Thanks Will, As always your expertise and straight up testing are the go to in Solar for the average guy.

I recently just switched all of our UPS batteries in our power UPS' to Vatrer batteries in the 12v 7ah batteries. They have been top notch. No issues. I'm also going to be using them in our kids Razor Electric Dune Buggy as well instead of the lead acids. Great video.

Thanks, WIll! We ended up buying the 200Ah Powerurus you have listed on your website. It's been great. Went with that instead of these ultra cheap ones, because the BMS has bluetooth, so we can see what's going on inside the battery. It's served us very well so far, thanks!

fantastic info, love your vids and very impressed by your knowledge / commitment!

I am very wary of the budget stuff, I wait and learn from experts like you about reliable brands. So far I bought two Redodo minis to start off with more than just the power stations. As a senior with some back problems, I was enticed by the more manageable weight plus the good reviews for Redodo, Power Queen and LiTime.

Somting wong with those batteries. Keep up the great work. Love your channel.

Valuable information Thank you

Thanks for doing the test of some of these 100 amp batteries there's a still probably a large group of us that aren't using server rack batteries

Thanks Will ! TAKE CARE..

Will i must thank you, with your videos i was able and interested enough to build my own battery with cells from a distributor (16x105Ah Cells its a 12V System) instead of buying one of these like in the video. And after 1 year, i looked up at the bms and i had only 30 made Cycles (my pc and the other electronics i can run with it and my power bill is now at 40% of before) And just top balanced the cells and holy crap. instead of 105 they had something like 115Ah on capacity. maybe its so, because i dont load them up very fast (in summer i get 25A max here with my little solar) - and overall peak load is about 40A... So thank you for this experience. i can only say to any other person, get comfortable with it, build it your own. its so much fun, and if something isnt working, you build it, you know exactly where to begin hehe Thanks

Thanks Will

That is the good part of you. You open and show us insaid even Inverters I seen you do same for acknowledge that good

Love what you do man, keep up the good work!

I really wanted another 400-600 amps for my boat and was looking at all of these batteries. I ran across some used Valence U27-12XP batteries with tested 120 amp capacity looking like new for just over $300 including shipping. I bought 6 of them without a thought. They all came within a week and looked brand new. Now I have 13 of them for the boat. With this many, I don't worry about starting big diesel engines with the. Even with 6, I had no problems starting the engines. The Bms in that battery is 150 amp continuous and 300 amp for 30 seconds. No problems any more and my search is now over

We had extremal fun time!

Finally, i have seen a few of these several times lately. I was iffy of these!!

Thanks Will. You really have helped so many including myself. You are a legend.

I wish your recommended batteries were available in Australia. It's a dice roll for good value LiFeP04 batteries over here.

@7:30 " Bigger the Glob / Better the Job" ! LOL

Your enthusiasm for batteries is fantastic 😂✌️

Those solder globs!!!!!!!!!!! WHAT!!! SO BAD!

This might be my favorite video yet. No. Wait. It is. What were they thinking?

Thanks Will, great as ever.

It would be nice to have a chart of who builds for whom in the market. Although I am sure it shifts around based on marketshare and pricepoint for some of these factories.

Great video! Thanks for disassembly and deeper review, not just "it works"! 👍😇 This video, probably, cost lots of money.. Safety first.. Some of them I, definitely, don't wanna in my house.. 😂

Thank you for all the work you put in to reveal the hazards companies and there products that shouldn’t me on the market the true danger of these batteries catching fire

Can you please teardown some of the new "mini" batteries?

Interesting video. You can get conductive adhesive/threadlockers for up to 200kv so it would be worth checking if that was the case. Probably not but maybe

Great job Will , thank you !

Thanks for doing this and I don’t know if they came from Amazon or not. If so it shows that with many products there is no QC and it’s usually you get what you pay for. It is really disappointing that there is a lot of low quality items online and the consumer is left to basically guess so thanks again for giving the lowdown on these batteries

Personally my top and most trusted source for all things solar!!! Thanks Will, keep up the great work you do here!

Thank you for doing this! Great information!

Thank you these videos help so much

Good gate opener battery tho!!! LOL

Thanks Will! I'm helping a gal with a trailer with a 120v refer and her 2 12v wet cells die at 2am. The issue is the plastic battery boxes are small, so the only lithium batteries that will fit are the minis. Grenerpower, GenhoalM, Weize. How about a video to help the trailer people. I recommended the Weize?

now THIS is a breakdown! great video!

You are a beast. I bet these manufacturers fear you reviewing their products. You help keep them honest. If they want more business they'll need to improve to pass your tests! I absolutely LOVE your channel, you are teaching me a lot. I just received my EcoFlow Delta Pro batteries with the 240V hub, but I'm thinking of returning them and building my own system based on your reviews. That EG4 6000XP looks fantastic. Will, I'm happy for how your life has turned. You worked hard and are blessed. FYI, my brother lived in Henderson, NV. I've been there, nice place. It does get a bit warm though!!

Amazon is carrying lots of weird battery names. Some of them are very cheap. I see one the other day for $197.12 V lithium ion curious if you’ve ever torn any of the Amazon stuff down

KIDS Building BATTERIES!

Thanks Will, you saved people money!😊

I would really like to see a teardown video with lithium motorcycle batteries like this. The market is quite the minefield. Seems almost nobody in the motorcycling community knows much about lithium batteries, I think it'd be beneficial to the community.

Already using it, don't care. I smoke cigarettes and am 20 years passed a terminal diagnosis. I am living on the edge. I'll give you a field test rating once I have it pushing 200 amps every day. It charges fine and powers my RV macerator. As far as replacing my 12v system... I'm waiting for my leads to die. I need to integrate my lead acid lfp or figure out a split phase solution. AC still needs 15 amps... crazy.

Thanks Will. You are my goto authority. Good video!

Waiting on a Scremower 400 AH battery!!

Thanks will would love to see a follow up on the weize 12v battery the price has dropped alot recently and I wonder if the quality is the same or worse

Thanks Will, you`re doing great testing all this junk. Keep it up

This is great, but there was a few brands 230-290 that I think you should really add. Some of us are new and tight on budget.

You ARE the Man!!!

Love your videos, I started watching them a few weeks ago on a journey to understand energy storage for my RV and propulsion for my little boat I am building. I have noticed that the brands seem to change so fast that review videos can't keep up, I hope you will keep tearing these things apart! Would you consider reviewing a cheap (sub $100) Lifepo4 charger for those of us who do not yet have solar? Either way I am subscribed and plan to convert my RV to lithium and solar as soon as possible.

Thanks Will.

Thanks will this has been a very informative video thank you for sharing this six stars

Awesome video, thank you!!

"The bigger the glob the better the job!" sounds familiar. Don't let the bumflow.

Could we get a power queen tear down please?

I appreciate these videos the most

Well done great content . Your a crazy man ! I love it!

been thinking about a 12v lifepo4 battery as the backup supply for a basement Watchdog emergency sump pump. they're usually spec'ed to work with flooded batteries, but mine at least uses a wall wart low current power supply to keep the battery charge. I've had SLAs connected to it for years and it hasn't roasted one yet, so it's definitely not pushing a lot of current. one of these lifepo4 batteries would safely supply enough power to probably keep that pump working for a month or more. :D

Thanks!
