Test/review of Golisi IMR26650 4300mAh (Gold)

Hope some day you will test them and we will know what they are like. Most probably, some high-drain type like PF.

I am not really interested in testing used batteries (Except when sold as new) and getting new Tesla batteries is probably not possible.

I think “like new” with minimum mileage (or cycles) is possible.

I am not talking about used or rewrapped cells, I mean genuine Tesla cells that may have different chemistry. I am not talking about worn-out batteries.

My problem is getting the batteries, the only offer I have had for Tesla batteries are from a old pack.

Yes, there is a point only if someone offers you a new salvaged battery.

Specs look very much similar to PF, but charging current is higher.

No it does not. Stop talking BS you read in Russian patriotic blogs.

This thread is a test by HKJ and my request concerns finding out the chemistry of Tesla cells and if they are close to any known NCR models. If you can’t tell the exact type then for God’s sake do not litter this thread.

What do you mean by BS / Russian patriotic blogs?

I think, and I am pretty much sure that I was NOT talking to you.

Probably, there is no need to remind that this is a general FORUM, and in no way PERSONAL correspondence with any particular person. Therefore, your questions about Panasonic in this topic about Golisi, in fact, are inappropriate here for everyone else, and not just for volchyonok.

They use very high capacity. There is no need for high drain once you consider how many cells there are.

Some older model vehicles used Panasonic NCR18650B 3400mah (possibly). The newer 21700 are around 5000mah.

Here is a thread where you can read more about the new cells.

It is widely assumed that it is 18650b, but people say that the current curves are different. It appears that there are several subtypes of the B.

Juste un autre ennemi à moitié plein d’esprit de la société californienne qui croit pouvoir exprimer son opinion de profane partout, même quand on ne le lui demande pas. Mépris :slight_smile:

It’s protected only in the sense it has a fusible link in it. It doesn’t have a traditional circuit board to protect it. You can see where it says 25A constant. No pcb protection board goes that high (to my knowledge). It is also listed as 65mm long. Normal protected batteries will be around 69mm or 70mm long.

Here is Banggoods listing:

Safety protection: S43 has a protection mechanism. It stops working immediately and permanently when short-circuited, no worries of flame or leaking.

We refer to this as unprotected.

The only one I know of is this Sanyo cell being sold by Vapcell.
It would be nice if you could test them, but I don’t want to get this thread too far off topic.

There are a lot of fakes of this cell our there. I would buy from known good sources, unless you just feel lucky. Maybe buy one or two from Banggood or Gearbest to see if they are legit. At least those are big companies and might refund you if they are fakes. From Aliexpress you never know. They are a market place made up of many stores, similar to ebay.

This person charged his different batteries with the same charger with a certain charging current. However, the elements do not like to be charged with strong currents, therefore when high currents are supplied to them during the charging process, they gain threshold voltage much faster and therefore disconnect from the charger earlier. For a battery with a large number of cells, its charger is relatively normal, but for a battery with a smaller number of cells, this device is too strong. It’s simple, you just need to be able to think like an expert, and not like a paranoid despising Russians, because not politics is discussed here, but equipment and batteries.

:person_facepalming:

Oui, c’est pareil pour moi, je n’ai pas compris de qui ni de quoi il parlait! Il aurait mieux de dire cela en Anglais peut-être que çà aurais presque pu vouloir dire quelque chose de compréhensible, mais là j’avoue, je donne ma langue au chat comme on dit en France, quand on ne comprend pas ou on ne sait pas une chose.

In english, for no-francophonic people:

Yes, it’s the same for me, I did not understand who or what he was talking about! It would be better to say that in English maybe it would have almost meant something understandable, but here I confess, “I give my tongue to the cat” as they say in France, when we do not understand or we do not know a thing.

so it is not really protected but not completely unprotected. So can this protection beware from burn or explosion?
