How good are these EVE 304Ah batteries? Worth buying?

The boxes, guys! Have we forgotten about the boxes??? I'm unpacking, checking, measuring and capacity testing the new EVE 304Ah cells from Qishou Technology in China. Very good quality, no dents, no burn marks, no condensation are just my first impressions. With voltage and internal resistance matched, let's do a full capacity test and get some curves on the screen!
The test of all 4 cells has not only exceeded my expectation but also the nominal capacity of the cells stated in the specs.
I'm impressed. This is the new standard!

Hi Andy, new to your channel a week or 2 ago I came across it and have now watch all your vids, I'm retired now and have been setting up a camper trailer to leave sunny(not) Victoria and tour up the east coast and follow the sunshine, returning to Vic during the warmer months. My setup started with AGM batteries but after thinking about the 50% suggested max drain this was a joke, so searched the forums and youtube for information on LPF, a week ago I placed my first order for 4 EVE 105Ah cells from Luyuan (also Amy) this was one of the suppliers mentioned on the DIY forum but it was your channel that made my mind up after learning so much from your videos, cheers.

[@john_in_phoenix]

Many vendors are selling bloated cells and saying they all are bloated from the factory. They also sell them as 310 or 320 amp hour cells. New cells are not bloated, and will not bloat unless abused, and the manufacturer rates them as 304 amp hours. They may indeed test higher, but many vendors are not telling the truth. I would have to check the spec sheet for the tail current on a standard charge. Looks like you received quality cells. Yes, I personally use 3.1v, but certainly not below 3.0v. The cell temperature will rise below this by about 5 degrees C. FYI, temperature differences can cause the difference in capacity as well. If you are really interested, take them into a temperature controlled environment for testing.

[@HappSsack]

Question for you. In your opinion, and experience. I see many people trying to address/ prevent buldging/ swelling through compression. Even the mfg. Reccomends compressing for extended charge cycles, even though there is a lack of instructions on the process. Do you find different amounts of swelling in different Ah cell capacity? For example 200Ah vs. 280Ah

[@OffGridGarageAustralia]

Tbh, I've never seen any cells 'breathing' during cycles. That's maybe mainly because I don't fully cycle my cells and use only a small amount of capacity with every cycle. Compression only gives you and advantage in terms of cycles if you have very high C rates. The test conditions specify the exact conditions for the test they did to get these additional cycles. Charging with 0.5C and discharging with 1C. Who does that at home? If you go away from that test environment, the benefit will be less or even vanish. I doubt you will see any difference in cycles over the life if you mostly stay in the 0.1C -0.5C range for charging and discharging between a compressed to none-compressed cell. It's good to see Will Prose and Lithium Solar coming to similar results and go away from this compression madness.

Hello Andy, I've been waiting for someone reliable to review these Chinese battery and found your video. Its fun watching your video keep up the good work. Fan🇵🇬

[@rcinfla9017]

A little suggestion you might try when you run discharge and charge tests. I don't know how many sequence steps your tester allows but if you insert a 5 minute no load rest gap every 15-20% state of charge points you can see how much terminal voltage drop to expect at your discharge rate when it picks up discharge again. In a five minute rest period the cell should recover to no load rested voltage. Five minute rest may not be enough to fully recover to no load equilibrium below 20% state of charge, The terminal voltage drop for a given cell current will give you an additional cell matching indication. Truely matched cells will have only couple of mV difference in terminal voltage drop for same discharge current. The terminal voltage drop is not just the cell resistance x current. If you remember the issue with active balancer if the cell terminal voltage drop does not match for same cell discharge or charge current the active balance may transfer in wrong direction. At 40 amp charge and discharge current (15% CA) I would expect about 35-40 mV terminal voltage shift after equilibrium reached around 20-25 degs C from no load rested for a cell in 280-300 AH range. The measured cell resistance voltage drop of 0.2 milliohms x 40 amps is only 8 mV of that 35-40 mV drop number. This terminal voltage drop is dependent on temperature and gets much greater below 10 degs C.

[@nateknowsmore4774]

Yeah what he said...

Sounds like a great measure for an active balancer to include?

They're branded as EVE|22 whatever that means... So they're not really rejected B grade, and they're rated at 1C. They probably just failed the 30 seconds 2C test or something. Of course I've only recently received 20 more QSO 304Ah cells at over €100 each 😭

Hey Andy, I ordered a set of these a while ago now. Unfortunately I haven't had a great experience so far. First of all they have sent the ones with studs, not holes to use my own studs, so their photos don't necessarily match the product. It turns out either version can be ordered, but I wasn't given the option. They have also not been able to provide working tracking information for about 6 weeks now. But apparently they are now in Australia and should be moving. Hopefully this is a one off experience, but all the little hassles like this are the reason I try to purchase from an Australian supplier myself. The language barrier makes it worse, but their lack of transparency is a killer. I only hope the cells are decent, because it would be a total nightmare to claim any sort of warranty refund.

[@OffGridGarageAustralia]

Thanks so much for testing these ⚡👍👍

[@OffGridGarageAustralia]

No problem, thank you.

[@craigjameslister290]

Hey Andy, Great vid as always :-) Wondering if the two cells that stored the most amp hours correlate to the cells that had the lowest internal resistance ??

[@OffGridGarageAustralia]

That is a good question. I didn't pay attention to that 🤦‍♂️ I guess, I can just measure again...

[@franks2354]

@@OffGridGarageAustralia also very interested in knowing this...

[@OffGridGarageAustralia]

@@franks2354 I'll do the test! 😉

[@evil17]

@@OffGridGarageAustralia What was the result Andy, did the 2 cells with lower resistance have the higher ah capacity? it would make sense that they were the 2 better cells I would guess. Don’t know how you keep up to all this and keep the great vids coming. Thanks & Cheers

[@dig1035]

Imagine 16 of these! Thumbs up and subscribed! Set skrews or studs! Those are huge cells! Cost vs 280s? 6am passion! Wish Australian or American made! 304ah is what in kWh? 304ah improves my days of autonomy! Appreciate your efforts!

[@john_in_phoenix]

Chinese manufacturers do not have to pay royalties on LiFePO4 cells, but those patents expire in April of 2022, so I expect there will be more manufacturers next year.

Where can I order these batteries from

[@jackoneil3933]

LOL "I was just about to ask" Thanks Andy, good review.

[@OffGridGarageAustralia]

Any time! 😂

[@PowerPaulAu]

Looks like you're going to need some more bus bars soon ;) What was the delivery time from order to arrival this time? And did you end up having to pay any extra customs charges?

[@OffGridGarageAustralia]

I got these ones with air freight, so it took less than 3 weeks. Just a 12V battery so far, once I buy another 12 of these, I will need more busbars, for sure.

[@jamesharlow6603]

@@OffGridGarageAustralia How much for the air freight Amy quoted me like 400 slow boat to US

[@OffGridGarageAustralia]

@@jamesharlow6603 I'll update the spreadsheet soon. Door to door freight was like US$160 for 4 cells. They should have them ins stock in the US, she said.

[@geraldgrogan]

Message from the DIY forum: posted right after this video was published "Gone! Quoted me $115 US per 304ah battery, but said US stock went fast."

[@OffGridGarageAustralia]

Thanks Gerald. So no US stock any more?

Is there a way to get a shipping quote without signing up? Is it safe to deal with Alibaba?

[@OffGridGarageAustralia]

I made a series of video about how to order, what to expect and what the costs are. kzbin.info/www/bejne/aGK8imd-fcmEj6s kzbin.info/www/bejne/pJ3Uno2YiZahg5o

[@GabrieleBertaina]

Curios to see the end of the video and test, but with very similar dimensions and weights I expect slim chances of 10% extra capacity... I think will be pretty much exactly same capacity max 2%... Lol I was wrong, nice cells!

[@OffGridGarageAustralia]

Hahaha, you commented before finishing the video 😂

[@MelonpanIslife]

Im watching this @ exactly 4:05am,, so its GOOD MORNING ANDY!!

What time zone is that in??? All video appear at 5am AEST. Good Morning btw 😂

[@nizamersoftware]

The prices are 50% down in just 2 years.

[@vladimus9749]

Expected to drop another 60% by summer 2025.

[@jedics1]

That is jaw dropping value, how much did shipping the 4 cost? I paid nearly double for about half the capacity about 2 years ago.. As someone who relies on my batteries full time this is exciting, they are even very close to the same size so they will fit in the same space I have now and double my capacity to make my winter easier and maybe even able to run an aircon in summer :)

[@OffGridGarageAustralia]

Have a look at the spreadsheet linked in the description. I keep track of all the costs there...

[@PAULNAT]

Good info there Andy, I will be looking into these as I am chasing a new battery set up for my off grid set up. 48v just up the road from you in Brisbane. thanks for sharing.

Next week i am about to receive 8 cells from CATL rated at 302 Ah .. they should be pretty much the same as yours i hope!

[@mihaitaiosub]

I received 32 such batteries (CATL 302 Ah) a month ago from Shenzen Basen.Almost all the cells were a little swollen. I wrote to the seller about this and he replied that these types of cells are always, from the factory, a little swollen.Please write to me when you receive them and tell me how they are yours.

[@michaelbouckley4455]

The Catl cells seem like Eve rejects, so Grade B or C cells. Maybe half of them bloated, and varying internal resistance. I have the 310Ah (which seem to have been downgraded). Worst thing is the welded fixed 6mm terminal screws, with 10mm dia. Bases, obscuring most of the terminal. The supplied bus bars are too short for any bloated cells. I have 8, only 2 connections still use the supplied bus bars (tripled). I bought longer heavy duty bus bars, and filed out the holes to fit 10mm, individually measured and fitted. Other supplied hardware was 8mm bolts and nuts!!

[@dauerwerbesendung7045]

@@mihaitaiosub unfortunately they arrived swollen and with some minor damage to them. not sure if i should send them back or at least get some money back. What did you do?

[@mihaitaiosub]

@@dauerwerbesendung7045 The cells I received were really a bit swollen, but the physical appearance was perfect. I did a capacity test and I got an average of 310-315 Ah, I measured the internal resistance of each cell and I obtained values between 0.2 and 0.24 mohms, so I kept them, I built the battery bank and so far everything is fine. What is the name of the company where you bought from?
