Thats disappointing, watched Will Prowse and a couple other people tear these open and they had the blue prismatic cells everyone is use to seeing. Was about to order their 280Ah model Amazon thats going for 589 assuming their entire lineup used these cells. After watching your video though I went back and youre right, they make no mention.of the cells or construction type... I mean for 12v 280Ah its still a great price but id much rather have the hard case prismatic
*THANK YOU. They are on sale at Walmart for $229.....now I know why. Great review KUDOS!*
Welcome 😁
This was a very important video! Makes me wonder how many other batteries have made this switch. It seems like the norm to put out a good product in the beginning then switch once they build a reputation. Before purchasing we must now ask which cells they are using. Put them on the spot!
When researching chins before buying my batteries I found it discussed that chins had a supply issue with prismatic cells and had to substitute with pouch for a short amount of time. Their customer service is great and all pouch cell battery buyers on the forum contacted chins and they sent them prismatic cell batteries as a swap out at no cost for shipping or anything. I bought 2x100ah 12v batteries, contacted chins as soon as I received them to ensure they were prismatic. They immediately asked for the serial number, then confirmed they were prismatic. They have performed as advertised and with my experience of their customer service and reading others experience I'm a fan despite the pouch fiasco. Sorry to see you had a bad experience! Be sure to get ahold of them and they'll send you a new one I'm sure. -Bob, B.C🇨🇦
That is some great information, Thank you for sharing your experience with chins.
can you post a link to your info ? thanks
@danieltimisan6820 no; that was 6 months ago. I believe it was on willprowse forum, but not certain. Search around and you'll find it.
that is not my expense With Chins i too would like to see the link. i am no expert but the bms would need to be programmed different as well or changed .
Not surprised at all that Chins and others would do something like this. That's why guys like you "might" keep them honest by exposing these companies every now and then.
We can only hope. Now I'm out 4 100Ah Prismatic cells that I thought were inside 😮💨 I can't even put the battery back together and sell it used. It's defective. I'll take the loss for views I guess. 🍻
I know lots of people purchased these batteries based off other reviews. This is such a shame. I’m glad you were able to bring this to light. Hopefully you’ll save someone else from getting a dud.
Before I made this video, I would have recommended this battery to friends and family not so anymore
That 4th cell is the first to hit low voltage protect, and the first to hit high voltage protect. Means It's lower capacity than the rest, and it will never balance out properly to get you full capacity of the battery. Bummer. I do however think it's neat to see different internals. Great vid!
You are right; I thought about that while editing the video. It will never get to full capacity. Thank you for watching.
Yeah you can only cycle the pack the capacity of the weakest cell. No different then lead acid though. I sometimes work on golf carts and yeah doing capacity tests on a bank of 48volt lead acid, 6, 8, or 12 volts.... still have to have fairly matched set.
@@john0270 For sure, One thing with golf carts I've seen is tapping lights into a battery to run 12V lights throwing the pack balance off more and more over time.
Good review. Thanks for all the work you put into it
Thank you for watching 📺
2:45 Lol like the wyns or BG tokens that were in the shop chemicals? 😂😂😂
Thank you for showing us this honest battery review.
You're very welcome 😁
I think this was a GREAT video inspecting and reviewing a costly battery that someone would hope to be a good investment. Great content! Great info! I've never seen your channel before but I'm glad it was suggested!
That battery sells for $200. That’s ridiculously cheap
That was a great reveal brother! Keep up the great work! Aloha!🤙
Thank you buddy 👍
Great catch, thanks
Bought 4 of these for a 48v golf cart. Burned out 3 of the 100a BMS's (even though my cart runs well within its operating specification monitoring current in real time). Ended up de-casing them and making a custom pack with a reasonable 48v 250a Daly BMS and they work great now. The construction of yours is way better done than mine was. Glad to see they used actual bolts to keep them compressed. Mine was just tape and silicone. Spec sheet says each 50ah cell is capable of 150a pulse, 100a continuous, so 4s2p config these cells "can" do 300a.
Really? A 2C discharge on a 50Ah cell. I'm suspicious of that. In any event I'm happy to hear you have the cart running 👍
@@Roll2Videos Suspicious as well, in any event the cart pulls about 70-80 amps while driving flat so having some piece of mind that the papers say 2c is always nice. No issues so far.
@@davidgreen8828 Perfect, I have some nice batteries coming for my cart. Stay tuned
Curious why you didn't warranty them? I have 12 Chins, and 4 Zooms. One of the Chins quit taking a charge. I contacted them and they sent out a new battery and told me to dispose of the bad one. Now I'm wondering if they sent me a pouch battery as a replacement. Also the 3rd set of Chins was advertised as having low temperature protection, and none of the others were. I'm not a fan of pouch cells. I think maybe I'll try weighing each battery to see if I can spot a difference
Nice work man. Thank you!!!!!
Thank you for watching 📺
I enquired to Chins as to the type of cells I purchased. They responded with soft pack or pouch cells (they determine by serial number). I complained for the same reasons as stated in this review. They agreed to replace the cells with PRISMATIC. I received a PRE-PAID return authorization and received 2 new 100A batteries from Chins stating the replacements were prismatic (I did not open). They tested to spec. I must complement Chins for their immediate response and cooperation. I even received the replacement cells before they received my return. If these new batteries are, in fact, prismatic I would rate their customer service as superior. YMMV!
That is great. I'm happy they helped you. My experience is I've emailed them three times. I even shared the link to this video with no response. I even offered to make a new video if they sent me the proper battery to pass my tests. No luck.
@@Roll2Videos the above reply has no videos, no subs . Gotta wonder
Good review👍
thanks for the video , good info
Thank you
The bigger chins use prismatic cells. Buy a 300ah and run the same test. I've noticed most the 100ah or Smaller are pouch
I have 2 Chins smart batteries. I had to balance both of them in order to charge over 14.1v. I have 4 Timeusb purchased as 2 sets of 2. One from each set was badly out of balance. It took about 2 weeks to get them balanced. Now my first pair will shut off at 14.53 to 14.54 volts and the second pair shuts off at 14.51 to 14.52 volts. I just spent another week trying to balance all 4 with no change, so that's as good as it gets.
That doesn't sound very fun. Great job working on them.
@@Roll2Videos More annoying than fun, to be sure. Rewarding tho, to be able to full charge without the bms kicking off. And I picked up 2Ah on the Chins and several Ah on the timeusb. (getting 110Ah and the bms is still alive!) I suspect the factory doesn't balance, or maybe they balance if the battery fails capacity testing? One of my Chins reported 4 cycles when I received it, the less balanced one only 1 cycle.
This is the second video on these batteries failing. I am happy that I did not spend my hard earned money on one of these. I appreciate the effort that people put into the review videos on different products. The owners of products need to be more honest instead of greedy. Honesty goes a long ways in my book.
We need more of it these days, Thank you for watching.
Who uploaded the other fail?
@@GTrainRx7 John Daniel
I run three of the 200AH in my RV, I opened them and pulled the cells out to save space, great cells and BMS (VIP BMS)
It's good to hear about your experience; thank you.
i wonder if that bolt from time to time was shorting one of the cells .That's why the lower voltage in cell 1?
I don't think so. The area it could move wasn't around any wires or terminals. Think it was just a bad cell on it's own.
Is that the mini version of the 12V 100Ah LiFePO4? It seems smaller form factor than what I have, that could be why it's the pouch cell version?
No, It's there regular sized battery
Question: If a pouch cell is used inside a casing, does it then become a prismatic cell? What I found on the web: A prismatic cell is a cell whose chemistry is enclosed in a rigid casing. Its rectangular shape allows efficiently stacking multiple units in a battery module. There are two types of prismatic cells: the electrode sheets inside the casing (anode, separator, cathode) are either stacked or rolled and flattened. Now I'm more confused. Either way, thanks for the video!
No, it's still a pouch cell. Excellent question. I'm happy you're taking time and interest in this topic.
It is likely you got one of their normal batteries. Most tubers they send out batteries they know is their best and others will buy based on the good reviews. I have been having issues two others right now, first (resolved) was an Apretime 200 Ah and right now an EG4 rack 12V 400 ... it is being sent back... less than three months of use and .. it still has 5 year (low) warranty. What are these quick money sellers doing? Reputation is worth more than gold or silver ... and people will say I am nuts.
Sucks to hear your bad experiences. Hopefully the future bring you better luck.
@@Roll2Videos Thank you for the encouragement
May I ask if cylindrical headwaycells good for solar?
I don't see why not, Chevk out youtube.com/@BradCagle he uses some cylindrical cells in some of his videos. 🍻
I don't think they're doing what you stated. I think they are sending known Prismatic Cell batteries out only to known reviewers (and maybe some other select people). And they are manufacturing and shipping almost exclusively pouch cell batteries for normal customers I would guess.
Very well could be.
Pwm may work a little too well would you sell lithium-ion phosphate battery and solar panel that is mono ceiling sales only manasi when shows can you be close more compatible
I'm sorry I don't understand your comment.
Was getting ready to order a deep cycle battery for trolling motor. Will take chins off list.
Yeah... Check out some of my other battery reviews 😁
Great video! Just bought my 5th and 6th Chins 100Ah 12V. Would you be able to weigh your new battery so all of us can use weight to tell the difference.Thanks!!
Great idea
@@Roll2Videos just weighed the 4 batteries two @ 22.3lbs and two @ 23lbs
@@donwilson7826 I'm sure it'll be ok. Just keep an eye on them.
Can you tel me if you know about lithtec lithium battery thank you for your excellent detail
I do not know about them but I will reach out. Stay tuned
Yes video👍 ⚡🔌🔋💡
Good review. I’ve dropped chins as a an option through my solar business. The newer ones with Bluetooth BMS really show how far off cells are. I had trouble with them shutting off under charge at 13.8-14v rather then 14.4. They also do not meet discharge amperage ratings. I’ve had them repeatedly shut down after several minutes at 80-90% rated continuous discharge. Fail on top of fail.
Oh wow, Great information thank you.
Bought 2 Chinn batteries 1.5 years ago and they are junk now. BMS wont wake up. Looking for new batteries for my RV solar now. Thanks
Omg, I'm sorry to hear that. What a waste of money. I've emailed them for comment with no reply. What a shame
@@Roll2Videos replace the BMS?
@@gilianrampart8514 It's not the BMS; there is a short in one of the cells. The best thing to do is to recycle the pack at the proper facility
I’m glad I go with power queen 😊
That's what I'm thinking on.
Where are the comparable tests for Power Queen?
All comes down too availability of the cells.. As it seem when prices started dropping. The Supply chain of the cells can not keep up now.. As the price son them are below $300.00 US now.. This puts them within reach of the average user now... But I would still use them. If they warranty them.. Until Graphene batteries come out.. As Graphene is going to change the world of Solar storage beyond anything out today...
The future looks promising. It sucks I couldn't get full capacity as advertised.
Where did you purchase this battery and do they have a year or month their craftsmanship failed
Chins website, About a year ago.
Now they have the 100ah minis in all brands you can think of and I believe they're all pouch cells which I think is a cheaper made battery at a higher price....I do not like when companies take advantage of customers trust and money...
Dude, the nut is right there on your bench!!
No, there was two terminal screws on the bench. Is that what you're referring to?
"That's different" Ha Ha🤣
Did chins send this battery to you or did you buy it from your own? If its from you own...then perhaps there is something to the these companies cherry pick units for reviewers and send something else to the average buyer...
This did not come from Chins. I really hope most companies don't do as you've described. 🤨
@@Roll2Videos A knock off battery like smartphones? That would be so easy.
I'd love to see a public comment from the company about this. A loose bolt is absolutely inexcusable at any price point.
I've reached out to them by email with my video link for comment. No reply. The worst part is that the capacity test was a fail which tells me there is an internal short in one of the cells. 🫤
They began using pouch cells early last year.
Thanks for sharing your knowledge!
Thank you for watching my video ✌️
Bought 2 chins 100ah batteries only lasted one season each. Used it on 24 volt trolling motor
Only 1 season? Wow that's bad
You sure it's lifepo4? I know that also make another chemistry battery, maybe it's mislabeled
I did not check the marking on the packs. Maybe in a future video, I can check that.
Did you top balance it and try again? How did you verify your conclusions? Not really seeing an issue, you could have returned it, or tested it with a top balance, only then might you have an issue... It would literally take less than a day to check the top balance... then you try to sell something else. Suspicious much?
Thank you for the comment. Yes, I did try to top balance and one pouch expanded to where it was almost going to explode, so I stopped. I was going to film the attempt, but I just decided to move on with my life. Thank you for watching.
I bought a 250 AH Chins for my boat on Amazon. It worked well initially but then refused to charge. After a bunch of troubleshooting, chins determined the BMS was faulty. Despite their warranty that promised a free replacement in the first year, they are refusing to do so. I won't be buying anymore from them.
Sorry to hear that. There are many stories just like yours with this company
that is sad 😢
No your wrong. Pouch cells are dangerous not used for specific purposes. In a battery case there not stable. Renogy was using them and stopped due to failure issues.
It depends on the chemistry.
👍👍🙂
Unfortunately I have more Chins than a Chinese phonebook 😂
Any problems with them?
Nice taking down of the scammers.
do you say lead acid battery
Can you give me a time in the video for reference
it's a shame that once they got a good reputation, they reverted to sloppy substandard work.
I agree
Possibly a cheep knock off of a cheep battery? I would not be surprised. Is it truly a chins?
Well, it came from the Chins website, so I'm going to assume Chins is selling Chins products.
Chins is short for "Chinsey"
If this did not come from Chins it could be a knock off like smartphones and,and,and.
It was not sent to me by Chins for review. It did come from chins without their knowledge of my intent.
I hate to be that guy, but... loose change?
It was a possibility
They used to be good.
We were shocked by the outcome of your test of the CHINS battery. Also very surprised they're using pouch cells. We need to correct one thing we've noticed and say this with care. It's battery cell capacity. Not compacity. Keep up the great work.
Thank you, I will practice this speech correction.
prismatic is a chemistry not a case style. bring it up to charge and top balance then test cap
I'm not sure how a shape (Prismatic) is a chemistry; this is a lithium iron phosphate chemistry (LifePO4). I'm attempting to balance the cells, but cell number 4 seems to not be absorbing the CV.
They should change there name to chintzy.
Hahaha hahaha nice
All the lithium batteries come from China. These have the best reviews on Amazon. Not sure what you guys think you are going to buy. Battle born is 60% more expensive with Chinese parts put together with American hands. I got the 300 ah chin on the way. They are second to battle born by the majority. Get your lithium before you can’t. So he recommends another Chinese battery with a lower review nobody has heard of ... lol
Yes dancer, Because I've tested and opened both batteries. I hope your batteries work perfectly for you.
I read all the comments on this battery at Amazon. It’s more expensive than Chins, and the customer service is nowhere near as good as chins. Any battery can have a problem, if I have a problem I want customer service to remedy it fast which chins does according to everyone. Any of these Chinese kids installing can make a mistake on any given day. The battery has a great warranty and service nothing less than battle born batteries, maybe better from what I’ve heard...
@@samcarrs Your comment about kids is pretty rude. You do realize a lot of these Amazon reviews are fake right? Like a huge number of them. You can trust that or someone who filmed all the tests and opened the battery and showed the internals. Some average Joe on amazon or someone who spends year's focusing on this very topic. All the best to you brother.
I have not seen any issues with CHINS either, sometimes reviews need to be "REVIEWED" ;)
@@Rook137 you own one,right?
spray electrolyte?? lol what?
?
@@Roll2Videos you said the battery could spray electrolytes
@@jeremyconner7610 Yes, That is the liquid inside the pouch. If it's under pressure, it would spray electrolyte
Looks like lazy Will Prose rip off,Of you found somthing wrong.
I disagree. I would say he was the victim of said company. They had changed the manufacturing practice after his review. He no longer recommends this company on his website. www.mobile-solarpower.com/lithium-batteries.html
@@Roll2Videos you're a good friend Peace.
@@daviddorsey8754 he's never talked to me, I'm small potatoes 😁 Later bud
I am not buying one of these even though I need a new battery bank. Typical Chinese company - zero ethics.
I wouldn't lump them all together; plenty of companies, even US companies, unfortunately, have practices like this, Thankfully there is a platform like KZhead for people to review products. I am happy to hear I may have saved you from a potentially bad purchase. 🍻
Then why even watch the review if these are "typical"??
@@Rook137 Right! Lol
So I guess you're only buying Battle Born then if you're ruling out all Chinese.
@@ItsEverythingElse No, not at all. Look at some of my other videos.
They're cheating reviews
That appears to be so
They are at $267 at Walmart......their 200Ah ($550) are prismatic cells
Good luck
@@Roll2Videos does that mean I should not buy it?
@@xbleriot That's up to you. I supply the information to the best of my ability. It's your decision to make
Chins is bad, part of a group of 12 in one importer union. But Chins has a problem, it's a WOKE employee ran all female with 3 USA women in charge. ( current politics in USA related to their bad decisions like Bud Light if your up to date ) so they are picking a lousy assembler in north China unlike its sister brands using south east china. So its poorest built in this line up. They are using same assembly makers as Wulills & LISUATELI tech and cells that makes Kepworth suck.
Wait, What's wrong with bud light? Quick, I'm standing in Target about to buy a case. I guess I can untuck and walk out of here; Canada has the best beer anyhow 🤪
Hahahahahaha
So what are the others that use better assemblers?
OH CRAP!! I just ordered this exact same battery. 🥹
Hopefully you'll have better luck
