Hello.
In this forum we has talked long and hot of BMS.
Today I have found out that all las baterias de litio de los mobile phones have an integrated BMS...

Such as the commonly used 18650 sized cells. https://www.ecoluxshopdirect.co.uk/by-s ... -protected
Or you can buy unprotected 18650 cells. These can be discharged to whatever voltage you want. And charged to whatever voltage you or your BMS chooses.
The idea being that the end user or consumer buys protected loose cells in the same way that you buy NMH AAs and similar for torches clocks etc. And then they are safe for use by dummies.
And the unprotected pure cells are for use with packs with cell taps, or by manufacturers, or with a BMS in say a laptop. Or with the PL8... hobby use.
The protected cells cant be charged in a pack in series. Because as soon as the first cell is "full" at 4.2V the protection opens up. So no current flows through any of the other cells. They are intended to be charged in a seperate charger like these: https://i5.walmartimages.com/asr/390f59 ... 6ac9ae.png or similar.
Or inside a phone, or whatever.
