    Quick question:
    Is this board a charger module + over discharge protection (up to 20A) or only protection?

    If it is the same protection, can you suggest some charger modules? They would load the 3S3P or even 3S4P packet

    Can chargers based on the TP4056 chip (without over discharge protection) be connected in parallel, thereby increasing the charging current?

    This is a charger with a balancer, i.e. with protection for even charging of batteries connected in series.
    EDIT I am correcting my mistake, this is just a balancer.

    Can not. There are chargers made of 4 pcs TP4056 "giving" 3A on the output. Example .

    Is what I have drawn correctly? If you couldn't suggest 2 tiles? Charging 3S 3A (or more) battery and over-discharge protection with 10-20A capacity

    Apart from (for a moment) both modules, how do you imagine charging with a 5V phone charger three batteries connected in series, whose voltage after charging is about 12.6V?
    And now the modules: the first on the left on TP4056 is used to charge one 3.7V battery (4.2V after charging) and a maximum current of 3A. To be able to charge with such current it must be powered from a power supply with current capacity over 3A. The phone charger is too weak.
    The second module - I have already written:

    .
    EDIT As above, I am correcting my mistake, this is just a balancer.
    Since the batteries are connected in series and after charging the voltage on them will be 12.6V, it is logical that it should be powered with a higher voltage than 12.6V
    Your drawing can be read like this: a 5V power supply powers the charger of one 3.7V battery, which charges the balancer of three batteries with a total voltage of 12.6V.

    rather a module ... for installation in a housing (portable speaker)

    You are wrong - look carefully.
    This is only a BMS for the charger.

    Actually, mea culpa. I had some darkness looking at it earlier. ;)

    Would someone suggest some charger for Li ion 3S3P in the form of a single module and not a professional charger? I want to put it in a casing so if it is possible it can be 2 plates

    And the charger you mentioned ... If I have a 3S4P package of which every cell has an average of 2200mAh, will the charger charge the whole package in less than 9 hours?
    Maybe some charger that has a slightly higher charging current? I was hoping for 5h but I don't know if it is possible and whether I will damage the links.
    And one more thing ... what is the difference between Li-po and Li-ion? Chargers same?

Topic summary

The discussion revolves around the functionality of a 3S 20A Li-ion charger PCB BMS protection board. Users clarify that the board primarily serves as a balancer and does not function as a charger module with over-discharge protection. Suggestions for suitable charger modules that can handle 3S3P or 3S4P configurations are requested, with emphasis on the need for higher charging currents to reduce charging time. The TP4056 chip is mentioned, but it is noted that chargers based on this chip cannot be connected in parallel to increase current. Users seek recommendations for compact charger modules suitable for installation in portable devices, while also inquiring about the differences between Li-ion and Li-po batteries.
