You got it exactly backwards and I bought two of these because of your video and I am one happy camper. You demonstrated beyond any doubt that this is the best battery for the money. Let me explain.
The sticky stuff is slastic and it is a good thing. It prevents the vibration that causes copper wire to fail from 'work hardening'. The solder blobs are are good thing - they reduce resistance and act as a heat sink. The short bolts are in spec as you can put several combinations of 60 amp connectors on and still get three full turns. The foam is a great thing, not just good, if you plan on transporting in a car. Dropping on a corner or slamming in a car door cause no damage to internals, as would be the case with almost all other batteries. The temp test was within spec - 79 is within the 75 +- 5 range. And while true that it did not cut off on over current, a 60 amp BMS surviving a 90 amp dump for 10 minutes is freaking stellar, so I would conclude it did not need to cut off (that said, I use 25 amp fuses for my use case.) While there was not a typical temp sensor, there are other ways to monitor temp and you did not show they were not using an alternate method (I don't think they are, but for my use case, I don't care.)
But wait, there is more (see replies to this comment) .
The problem I had in making a decision is the reviews on lithium batteries in general, are bad. But after weeks of looking at different batteries and hundreds upon hundreds of reviews, I realized that the complaints were basically the same for all lithium batteries. Even for the so called, top of the line batteries. So the reasonable conclusion is that the complaints relate to the reviewers state of knowledge about the generic product and not anything about the specific product.
And that really is the heart of the matter - especially for those experienced with lead batteries - the technology and behavior are entirely different than what we are used to. The learning curve is steep because none of the tried and true applies anymore. They don't act the same, charge the same, store the same, or suffer the same problems. You need different chargers, different charge profiles, and most important, you have to know your use cases.
About 'use cases'. If you plan to draw high current on a regular basis or as part of normal daily operation, that is quite different than occasional high current, or rare high current. Likewise, there is a difference between daily life support (wheelchairs, handicap scooters) and the truly important things in life, like trolling motors and beer coolers. And using LiFePO4's as your energy back up is different than using them to stabilize a small solar array. You have to know your uses cases or else you are just making a fashion purchase.
It costs money to learn poker, and even more to learn Lithium.
A little more about uses cases and cost. I have never had a handicap scooter battery last for three whole years. The first time you are too tired to take it out of the car in winter, the batteries are damaged forever. That is the main reason I bought lithium - I don't have to take it out of the car every time. 50 AH is way over kill for replacing a 35 AH AGM, but I have a second use case, which is to make my 500 watt solar array useful in day time only. I am not using the batteries to store power at night, but rather to just balance the system. For both use cases, the batteries never come close to going below 30% charge, and so should get a lot more cycles in their lifetime. While it did not occur to me at time of purchase, I realized that I did not need to buy a new battery for the camper as the pair of 50 AH batteries is more power than what they would be replacing. So in my case, the choice was $400 US to satisfy all my needs, or multiple AGM batteries - 35's for the scooter, and a 150 for the camper and solar. If they make it the 7-10 years they are supposed to, then they are half to one third the cost of AGM. Note this is not at all the same as using them for a trolling motor or beer cooler, where you will fully drain the batteries every use, but use them less often. Also, the previous use cases are not the same as constant high power drains, like running high wattage appliances. If you don't know your use cases, then you are just making a fashion purchase.
Thanks for watching and taking time to comment. I'm delighted that the video helped you make an informed purchase decision and the batteries meet your requirements.
@@DCGUY No Problem. Glad to help. These tear down videos are important for those of us who don't follow the rules. And your review of the fake MPPT controller was huge eye-opener for me. One other thing I noticed. I could not find where the manufacturer (Eco-Worthy) made any claims on this particular battery as to temperature or high current protection. I have only seen those claims on eBay, Amazon, Walmart, Ali-Express and most other re-sellers. If you did see it from eco-worthy, could you post the link?
I'm going by the data sheet I received with the battery when I bought it, you would have them too with your batteries. Specifically states Max charge voltage 14.5v, Discharge Temperature range - 20 - 50⁰c Max discharge 60A. Temperature control 75⁰c and so on. The bms manufacturers told me via email that over temperature protection was built into the BMS as well. Their websites (dot com and UK) show over voltage protection. I personally like the eco worthy battery's they offer value for money and I'm still using 4 x 100ah daily. In case you are perhaps thinking, I do my best to give unbiased views and want people to make informed choices not based on sponsorship or paid promotions. People will buy what they can afford and if used properly e.g not pulling too many amps they are fine. My concern is the fact the battery BMS didn't cut off as I expected. Again thanks for taking time to comment, I do appreciate the feedback.
Hello,
I have bought months ago 2 x 30ah for parallel.
And opened them the day of delivery.. For the purpose of my needs they are okay!
I was disappointed to, the bms inside reeds 25ah and NO temperature sensors in both 👎🏼..
Tested the 30ah delivery test, and both Succeeded.
Great videos you make!
Keep on going!!
Greatings from the Netherlands 👋🏼
Thank you for taking time to watch & comment, your support is appreciated 🙏
I was waiting for this review before I went ahead with purchaseing the 50 ah for a 45 lb thrust trolling motor, glad I hung on, thanks for the info. I watched your video series on the 100 ah and that looks good in comparison but more than double the price. I will be watching your follow on to this.
Thanks for your valued support. Yes the price of LiFePO4 batteries are prohibitive but in time they will hopefully become economically viable for all.
How does it work with your trolling motor? I'm thinking of getting one my self
I was going to order the 30AH today direct from Eco-worthy but thought let's see if there are any reviews on here. Thanks you just saved me £140 as you and others have pointed out the quality is lacking, no temp cut outs on some so I may go back to my original idea of AGM. Thanks again, a useful review.
Many thanks for watching and taking time to comment. Its appreciated.
Hello, thank you for the detailed tairdown. If I gently press on the casing of my 30Ah Eco Worthy, you can hear the foam/tape crackle very slightly. I'm not impressed by the pouch cells so I'll use this for extremely light loads from now on. I bought an Ecotree Lithium 12V 24Ah battery a couple of weeks a go and the M5 terminals are much deeper and you get a pack of brand new insulated M5 screws. My Eco Worthy's screws were slightly stripped when it arived but the case had no marks. Thankfully capacity is spot on. The Ecotree uses cylindrical cells and you can't hear any tape crackling if you push extremely hard on the case. The battery is sealed but capacity and a sustained 2C output are bang on with a 3C surge for a few seconds plus you get a 6 year warrantee with a proper UK company with UK staff who don't write in Chinglish. They provide all the UN38.3 certification numbers as well which is reassuring.
In future, it would be good if you could look into Ultramax 12V LFP batteries both the standard lead acid case varients as well as the golf trolley type which use T-bars and standard Powerpoles as the golf trolley varients can sustain 25A and burst to 35A for a few seconds with no issues considering how compact they are. I use a 18Ah golf trolley battery with my SG2 and 8TB 3.5 HDD and Victron 250W all using standard PP connecters with a lot of curious questions from the public who are interested in the battery specs.
Sorry my comment is so long I love your review style and all the detail so please keep the videos coming.
Thank you for taking the time to watch and comment, I really appreciate the feedback. I've been looking at the different battery suppliers in the UK including renogy and the one you mention. There are not that many out there, our cousins across the pond have lots of choice. Pouch cells aren't all bad, they are common for smaller capacity batteries as are cylinder cells. Again thanks for the feedback 😀
I have just repaired one of these. The Negative lead had come off the BMS because of a dry joint. You can really tell they didn't give it enough time with the iron
Thank you for the tear down.
I have an Eco-Worthy 12V 30Ah battery which I use to power my ham radio, and it does the job. So I was thinking of buying the 50Ah.
I looked on Amazon to see if any 50Ah had the bluetooth monitoring, but that only seems to appear on the 100Ah units. Perhaps as your tear down reveals a bluetooth BMS could be used to replace the supplied BMS?
From what I can see in the video, the quality of the soldering looks fine. It may not be pretty, but nothing looks cold or anything. It's perfectly fine.
If they had more heat energy, it would have flowed better. There is a lot of metal there pulling the heat away.
Thank you for this video, for showing what's inside the box. What a surprise!
I am looking for a lithium battery for my boat, I already have 2 trojan 6v T105, but I need more energy for the days without sun.
I am planning to add a distinct circuit, from solar panel to socket using a lithium battery.
Am I correct, in thinking that for lithium batteries, it is better to have a smaller battery that goes trough all the capacity rather than a larger one that very rarely get discharged ?
Thank you again.
You really need to size a battery to any potential demands that will be placed on it. An undersized batteries life span will be significantly shortened if its over working. Depth of discharge is greater with lifepo4 but as with any battery chemistry the harder it's working, the shorter the lifespan. I'd rather oversize my battery than potentially undersize, especially on a boat.
@@DCGUY Thanks , I will think about it.
Wow thank you for doing this video. I picked up one of these to use as a house battery in my SUV. Recently I became concerned with temps because I was doing some testing and the ambient temp became 102deg F in the area where the battery is stored. Not too bad but it is only spring here in southern California. I can't imagine temps when it's full on summer.
And now with your findings of no temp cutoff sensor concerns me. I will reach out to the mfg tomorrow about it.
Other than the temp sensor and that it is cheaply made. Would you think it's ok to use ina bumpy environment (off road vehicle)? Thx!!
Thanks for watching and taking time to comment 👍 it's a difficult question to answer as these are made for static placement however I personally don't see any potential issues if used with your atv.
How did you open the battery? With a heat gun??
The main issue i find with Chinese electronics is very poor QUALITY CONTROL or total lack of, especially with the unbranded items, the bigger end manufacturers like Renogy and auxbeam have a much better QC 🤔
You really do have pot luck with lower end brands it seems ☹️
Really enjoying the channel chap 👍 keep at it 😎
Yes it's certainly a lottery. Thanks for taking time to watch and comment. Really appreciated 🙏
In Chinese products, anything that can be hidden will be hidden. Anything they can get away with they will get away with.
You have to go 100ah on these to get to the prismatic rectangular cells. This isn't a bad showing though!
So what manufacturer would you recommend instead? Was looking at this one
Hi Val, is 50Ah adequate for your needs? If so these are fine as long as your not pulling a high current continuously. The fogstar brand are decent but not sure they have 50Ah. Ultramax have a 50Ah battery, they are decent batteries too.
Hey ive heard alot of good things about Krohm batterys. Have you heard of that brand before?
Not heard of that brand.
good jop！
Just use longer screws
Ohh dear just read the comments. Looks like a 100ah lead acid would be better. I'll check out your video over this coming week end.
The findings weren't good I'm afraid. LifePo4 is still better value over lead acid, its just the cost up front that stings. I have no doubt there are good 50Ah lifePo4 batteries out there, just not this brand. I did a review on a 130Ah lead acid which can be viewed here ua-cam.com/video/hxD6bkg49R0/v-deo.html
Have you considered a self build?
@@DCGUY I've been looking on AliExpress for a LiFePO4 100ah. What's your thought's?
It's a lottery I'm afraid. I can't recommend any particular brand or seller, but I would say do your research. Check how long the seller has been in business, ask what cells are used, what bms etc.. If in business under 3 years move on. Always check reviews, look at one star reviews too. Pay with PayPal. Be prepared to wait as they usually have to be shipped not flown. Consider buying cells and going DIY. EVE cells are good but often faked. Check with Amy Zheng of Docan Power for availability they are the manufacturer of eve.
@@DCGUY Thanks for your wise words and top tips.
@@markweatherall7437 oftentimes the shipping totally consumes the potential savings so ali doesnt seem to be worth it. I found another german video were a battery from alibaba was recommended but as I said… shipping fucks it up, additionally no guarantee and so on.
Oh I bought the 100ah am running marine electronics with it should I be alarmed
The 100Ah is ok you needn't worry. I've reviewed those and I'm still using mine. Just the 50Ah that let's them down.
Thanks so much
Hi I purchased this battery. I purchased 50ah with 12.8v. Is this battery really a lithium iron phosphate battery? It has very little capacity. Also, the voltage does not rise above 13.0v. A new battery will normally be fully charged at 13.4V. I've already purchased it 3 times with the same result. Is this battery really a lithium iron phosphate battery?
I cannot be 100 percent sure these days what eco worthy are using.
I knew it! the china battery is so low quality from a japanese perspective.@@DCGUY
It's like a Russian Doll - A Battery inside a Battery inside which. even more batteries!
Dang! This battery is total junk! Some of those cells were already swollen! I was going to buy one of these just today and accidentally clicked on your video! So lucky I watched your video! I'll never buy one of these!!!! Geez
The 100ah were a bit better, but the 50ah is probably the cheapest built battery I've seen. Maybe I was sent a bad example, old stock perhaps but I was very disappointed regardless.
hello you think i should change the bms on the 50ah? i just bought in
Got 4x these. They have been working fine for 3 yrs. What ya expect for HALF the price of every other option available on the market?
This doesnt look too promising… any hopes of you comparing several 50 Ah ecoworthy batteries like u did with the 100 Ah?
Absolutely it would be interesting for sure though I keep an open mind.
Wondering what their 260ah battery would be like . I could use 2
Let us know how things go if you go with them. Cheers
This technology can't go in flame even if there is a default they will just expand and explode if needed, so they are safe
am i the only one who read the title in randy marsh' voice?
Not very impressed with this battery.
Never buy these. They ship 7ah in the larger case and hope you don’t catch it. Never buy these.
