You are right, it probably does not have a protection PCB, but it is not totally unprotected.
HKJ has written a detailed explanation about protected batteries, follow the link to:
“How is a protected LiIon battery constructed” in the OP.
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.
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.
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.
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
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.
