help me choose between these 3 lifepo4 battery cells

[emelina]

Hi,

I'd like to purchase (x4) lifepo4 3.2V cells to make a 12V battery for my van.
I am not looking for grade A or top notch batteries, I just want to build a 12V battery for my van that can handle a few thousands cycles, with a capacity of about 200Ah.

I am hesitating between these 3 ones, they are all rather cheap but the first one is veeeerrrry cheap for a 320Ah.
The 2nd ones have a strange shape I've never seen before.

Could you please tell me which one I could buy without being scammed? (my knowledge about lifepo4 techno is limited to what I've learned on yt )

I wrote a few message to the sellers, they seem fine and communicative. Their ratings are good too.

I know you prefer better quality batteries but my budget is limited...
Anyway here they are, thanks !

I know this guy and his content is top notch I learned a lot from him.
But it does not answer my question

If I had to choose between those three.

The first is out. Item 420. I don’t like the cases.

Of the second two. I’d lean towards the last link. Item 400. They are so close looking to Winston cells that they may have been made by Winston.

A comment from a purchaser suggest these are CALB cells

thanks for your feedback. I'd go with the last one then, at first it surprised me because I4ve never seen green cells, in a stretched format. The drawbacks is that they don't include busbars and screws, like the other ones.
Btw, what do you mean by Item 400? and "item 420" for the first one? and the case, what is the pbl with it?

This is no good?

[mitiempo]

Calb, Winston, and Sinopoly are all top notch manufacturers.

Somebody sent this to me as an argument why not to do what you plan to do. I am scratching my head after watching it - "should I...?"


What is your reason not to follow what he recommends in this video?

Yes that was my concern about the first one, I've just read his reviews and I saw he sometimes have the same text reviews from different buyers, so obviously fake ones.
I will follow your advice and buy fr the other one. Thank you much !

His recommendations are all over the place

If it’s helps in real applications the biggest most popular battery “ manufacturer” is half a size good as their claims from China dozens of them can’t be imported here. Putting Chinese cells in a domestic case is a popular scam also. You could pick up a BMW i3 battery pretty cheap because they were not that great but will kick ass in a van.
The First Rand Picnics used this cell in their early boats.

The item numbers I’m typing are the last three digits from the links…..because I’m too lazy to name each one by their alibaba marketing names.

I’m not a fan of the aluminum cases with the blue plastic insulators over them. Not a big deal to isolate the cells with additional thin plastic sheets between them, but why.

Finally bought these 320Ah

Honestly if I end up getting a 200Ah I'd still be happy for that price
