Thanks for opening it up, inspecting, snd testing. Although the price is attractive, the less than desirable quality, would seem to indicate that other, unseen "shortcuts" have been taken.
The direction you were pulling on the strap was about 90° from the direction of the 'compressor' fixture of the battery. Still most of those types of straps are hard to release by pulling. My guess is it was either not hot enough or tight enough or both when fixed into place. Thanks for the review.
I wonder if having the cells the right way up would make a difference in the capacity output. I am guessing they are put in that way just to make them fit in the battery box. Not the best battery I have seen from Weize. But glad you opened it up.
To validate your results, you should at least make two capacitances test to confirm your results. It would be nice to see if those output as intended. 🤔
While I do understand your point and agree to an extent, I test all of my batteries the same way so if 19/20 pass on the first run, why should I give the 1/20 a second pass? That's why I'm hesitant to simply discard the first results. I might test it a second time here, but I still need to report the first test results to remain open and honest.
I went with WEIZE for my ATV one year ago and it works perfectly. The quality has gone down from what it was before so I will not use them in the future
Great review! It’s always insightful to see a detailed teardown and performance analysis. While this 48V 100Ah LiFePO4 battery has some interesting features and a competitive price point, it’s clear that balancing and cell quality are crucial for optimal performance. At Enjoybot, we take pride in our rigorous testing and quality assurance to ensure our batteries meet high standards. If you're looking for a battery with advanced features like self-heating and Bluetooth monitoring, feel free to reach out.
Thanks for the video. Im still learning, what were the individual battery specs? I saw some grade a Eve 3.2 105ah batteries for 39 bucks recently for a diy but after everything the savings isnt to much imo.
What would you recommend battery for your own home budget friendly EVE LF280K V3 Grade A Cells - 3.2V LiFePO4 280Ah Battery do you recommend this best bang for buck?
Their smaller 12v batteries appear to be of higher quality. Those cells are likely a new manufacturer that hasn't got the additives and coatings down 100%.
I don't think they're used because I was able to hit the rated capacity on the second test (after balancing). I think they're just lower quality cells.
He said he would cut the price to the price in the picture on ebay on 8/26, but he hasn't updated the listing yet. This will pay for itself in 1 year here in Cali, within the warranty period... so I'm tempted.
I have 4 different cheap 12v 100ah batteries bought brand new in series for 48v 100ah connected to my 2 lv6548. Each night after the sun goes down they keep dieing on me after 1kwh even though I'm putting 3-4 kwh in them through the day. 1 of them always dies and that triggers the BMS to turn it off. How do you balance them with this inverter? Use the AC input at 2-5A charging?
Shoking quality. I wouldnt touch it with someone else's barge pole. Undoubtedly grade b cells. Initself not a problem if theyre matched and build quality is good. I am of the belief that all batteries should clearly state what cell type manufacturer and grade are used 😊
@@LithiumSolar Electrical power is more efficient with copper plus higher heat/current compared to aluminum? Aluminum overheats if anyone ever takes a temperature gun you will realize this that those bus bars get extremely hot. Copper that is tin plated or silver plated or nickel plated is preferred and at that point it’s hard to tell if it’s aluminum or plated copper by a video that’s why I asked.
I don't know why companies are doing that. I understand 15 x 3.2V = 48V exactly; however, voltages at the low end of charge level does not work on most 48V inverters on the market.
1:32.... I would do on identical non balanced Discharge test as the 1st test and see if the results are the same low capacity. I never trust the very First tests I do until I can repeat the results .

For $100 more you can buy a eg4 server rack battery
48V batteries are so much cooler than 12V. Thanks for the review.

Ooooh that's a very interesting theory! Maybe I need to leave them on their sides for a few days then run the test again.
Alright, batteries are back on their sides. I will leave them sit for 2-3 weeks and try another test (or a few of them).
Looks like it has a similar built quality like the 12V 100Ah version and a similar branded BMS... Thanks for the video!

Glad to hear it's working out. Which one did you get, guessing 12V based on ATV use?
@@LithiumSolaryes I do use a trickle charger and I’ve never had a problem.
I did the same, mine died at 11 months, but thankfully still covered by warranty.

Nice video.. was interesting. Thanks
I'd rather have the waterproof EG4 100AH with 200amp BMS for same price.
Good review!
Didn't they stop selling those for some reason? I see they're only carrying refurbs now and looks like the new-condition listing is gone (still).
@@LithiumSolar did not notice. Been a while.
What would you reccomend for a good value and quality 48v 100 amp hr ish battery for a golf kart?
What would you recommend battery for your own home budget friendly EVE LF280K V3 Grade A Cells - 3.2V LiFePO4 280Ah Battery do you recommend this best bang for buck?

Why would they use different cells in different capacity batteries
Guessing the internal resistance of cells are not the same,or bms is not balancing correctly
Good review. Thanks
You sure the cells prefer to be used upright? Never heard of that one before…
Maybe they installed the busbar upside down for clearance in the case.
Maybe, but if that is the case, then they need a bigger case lol.
wondering if the 2000 cycles hints that the cells could be used ?
I don't think they're used because I was able to hit the rated capacity on the second test (after balancing). I think they're just lower quality cells.
16 x €35 = €560, €40 for BMS. Almost $350 is for a plastic case?
You should review 12v 100ah dc house batteries. They are $575 for 48v 100ah
are you sure its not a 50ah
I couldn't find it at that price either. The cheapest I see is $750 with a $150 coupon code that's currently active on Amazon.

Tnx
Like the price but that is about all. I would look elsewhere.
Which batteries have you tested that are using copper components including copper bus bars?
There is nothing wrong with aluminum bus bars. In fact, that's the preferred choice as the cell terminal are aluminum as well...

Thanks for the video and I will NOT be purchasing this battery and will go with a server rack for the same money!
Most 48v lifepo4 have become 15S. Sadly.
I don't know why companies are doing that. I understand 15 x 3.2V = 48V exactly; however, voltages at the low end of charge level does not work on most 48V inverters on the market.
Well,the price is going down but so do the quality lol
48v its fine
You’d be weize not to buy this battery…. Amirite?
am i wrong to assume this is the same company in Austrailia that is SUING a fellow youtuber for a negative review of their product?
No, that was DCS (Deep Cycle Systems). This is WEIZE.
wrong company--- have a search engine?

Pack them in😅😂
