Thought they said lithium iron phosphate (LFP) does not catch fire nor explode?

mctfopt:


CATL is not superior to EVE cells, the issue is will you get the real EVE cells? Many sellers sell fake EVE cells. Better you buy an original CATL cells than a fake EVE. But if you are sure of your plug, EVE is better

mctfopt:


LFP do explode. But it may not catch fire. Here is one that a friend had that was consistently overcharged without BMS

By that logic,.....CATL 240 ah should be able to handle.

Those that are using Jbd bms, what is an average MOS Temperature of the bms while charging the battery and does it have a stopping point.
I connected 150A Jbd bms to charge 48v 160ah lfp today. As the charging amp/watt was increasing, the bms MOS Temperature was increasing which is normal. At about 1800w going into the battery, I was seeing the MOS Temperature of about 36'C.
Unlike my Jk bms that the MOS Temperature does not pass 32'C even when I pumped 2500w into the battery.

With this price if you are patient and can wait 3 months for shipping, are willing to learn, you are better off ordering certified automotive grade cells and a diy kit and have peace of mind…..and for less money. To me there is a level of spending where he “F” batteries makes no sense for what they are. I am yet to see any review of any “f” battery where the tested capacity matched the claimed capacity.

By that logic, all CATL cells on the market are grade B cells. The only way you can get a true grade A CATL cell is either in an EV or in a battery from a reputable battery manufacturer, in short there is no way for you and I or any Retailer to get his hands on a true grade A CATL cell. While it is true there are a lot of dodgy Eve cells on the market, you can get certified automotive grade Eve cells, you can even buy from Eve directly but ALL the CATL cells on the market are rejected cells. So I would say buying a CATL cell is perhaps more risky than buying an Eve cell because you know for certain it is a rejected cell..

If you read the solar forums and look at the places that have emerged as the source for reliable cells (including certified automotive grade) in their respective countries e.g Sunfunkits in the US, fogstar in the Uk, gobelpower in china, Nkon in the Netherlands, none of them stock or even advertise grade A CATL…because they aren’t available on the market. Of these the only ones who sell CATL clearly state they are grade B cells.


Once you are dealing with grade B which constitutes most of the batteries on the market, you are at the mercy of 1) quality of the cell, I.e you hope it is what they say it is 2) the cells match so they perform well together in a pack.

I would suggest that you disavow yourself of the notion that because the EVE market has been bastardized, CATLs on the market are any better.


As for the different battery choices,

That a battery contains a particular brand of cells does not mean they contain grade A of that brand. Felicity uses CATL for some of their LpBF batteries, so does this Nruit. However if you check the continuous and maximum discharge specs for CATL cells and compare them with that in the Felicity or Nruit battery, it is clear they both use Grade B cells, perhaps weak grade B. Whereas if you check the spec for Eve cells and check the specs for the Deye battery it would suggest the Deye battery contain grade A certified cells. TheDeye I checked has recommended continuous of .5 c , Maximum continuous charge of 1c and peak of 1.5c whereas the recommended and max continuous max charge for the Nruit is 0.5c or less which is usually a sign of lower grade cells.

I didn’t check the dryness but between the Deye and the Nruit, it’s a no brainer…for me.

Hello house

It's 4 weeks now @chichilas wrote a defamation of character review on google that

1) I stole his cable
2) I damaged his roof

I will like to update the house that he has received additional cables since 3wks ago, was called and he confirmed he received his cable

Secondly he never told me anything about a leaking roof since around 2019 we installed for him. There have been several modifications on the said installation by other installers which I have also offered support remotely. We have spoken several times on the phone nothing of a leaking roof was mentioned.
He suddenly remembers his roof is leaking towards the end of 2023. No evidence and nothing.

Since he still have issues with the cables, I have since then requested he sends the cables back to us and get a refund which he is unwilling to do and I don't know why.

@chichillas also @theoilguy is very toxic and I don't wish to do business with him furthermore.

Tell him to pull down his false review. I did not steal his cable and did not damage his roof.

I hope nairaland mods will one day do something about defamation of character.

@mynd44

Chichilas:


Cry cry baby… so you do not want to do business with me anymore? LOL. do I wish to do business with someone like you too? I am not pulling down any review because that is exactly what happened. Take a lawyer and sue me if you think I lied and all the evidence will come out. Do you have pictures of the two pieces of cable you sent to me?

Is my roof the first roof you are damaging on Nairaland?

Am I the first client to have issues with you here? If you want me to do a search of the other clients you damaged their roof, I will post proof.

So what is new? A simple search of your antecedents will tell prospective clients what they need to know.

I wanted you to feel the pain and anger I felt when you insulted me on top of my money and patronage for no fault of mine. I see you have felt it now so I am satisfied.

DO NOT THREATEN YOUR CUSTOMERS.

The internet is very powerful.

Chichilas:


I have no grouse with him. I do not plan to even patronize online vendors on Nairaland anymore. A brick and motar shop is a better option.

A proper apology would have sufficed weeks ago but he choose to drag the matter on and continue to run his mouth and call me names on Nairaland forgetting that some people have time and energy and can go all out to right a wrong. It is too late for an apology now and I don’t need it. There is nothing I need from him at this point.

I just wanted him to know that as an online seller, you have much more to loose than a buyer so treat them right especially one who not only is a return customer but also recommends customers your way. I hope he has learnt his lessons.

As a lot of people here have opined, “the internet never forgets”.

it's like saying "unLimited" bandwidth or diskSpace or memory or ...

Am still in thought Chief

I don't blame some clients we come across saying;

- Install panels outside their roofs as carport/ swimming pool ports to avoid roof leakages , fire etc

- Install batteries , inverters outside the main building for similar fire reasons .

I've also come across several indoor installations running over the years without issues. Battery temperature sensor connected to ESS charge sources also need to be considered in most power system designs .
Guess lithium chemistry needs to be seriously studied especially now we've refurbished cells, substandard BMS et al hovering around the market esp in Nigeria . God help us

A single testimony from a satisfied and verified customer, is worth more than a million advert.

Sellers using proxy accounts to promote they brand, you are only doing more harm than good to your brand!

what about i-d-i-o-t-s like Us wey no dey use testimonies wether good or bad ?

Thanks for this piece, na to calm down complete the money buy the Deye stackable battery jejely as they're the only ones with specs with that of the manufacturer of the cells out of the 4 options I have (Deye, Dyness, Nruit and Felicity).

bassdow:


see eh, I have various things I invented, or alternate ways of doing some things I can't easily do for others NOT because I don't want to, BUT because I know they don't have the knowledge to maintain such.

Have had to suggest relocating battery bank because the temperature where it was situated was so unPalatable

Ok, I'll have to wait for them to have the 5kwh in stock as they currently have only the 9kwh and 12kwh.

Thank you

I usually liken batteries in series to a chain links that made up a chain, if a particular link is weak, the chain is now as strong as that weakest link.

Eg I remembered when one of the cells in my 16s 48v ebike'$ battery got lower than others, this lead to the bms cutting off supply to the motor when I'm riding it. This is super annoying, thankfully my BMS has Bluetooth so it was easy to fish out the rogue cell and charge it separately and we are good to go again. Battery pack is still performing wonderfully till date.
