    Hello all,

    I have several TP4056 modules and I need quite a lot of power, and chargers loading several pieces at once are expensive, maybe I could use them somehow? I drew a simple "scheme" will work it?

    If each link is loaded separately, it will work. Output OUT does not connect. The power supply for all this must have adequate power.

    do you want to connect these links in parallel yes? have these 4.2V and a correspondingly larger capacity? or in series and have these 16.8v?

    .... parallel ... I would like more capacity.

    It's just connect the links in parallel. If the charging current is also to be larger then the charger modules are based on several TP4056 chips:

    In this case, you can, for example, connect these cells in parallel (if they are in a similar state: degree of wear, capacity) and buy a ready charger or make a charger for them based eg on LM350 (3A). In this charger you need to have a current and voltage limit of 4.2V. In addition, you can give a security chip on each link (they cost a penny). In general, even one ordinary TP4056 could charge it, but at max current of 1A it could take a lot of time.

    Thanks to all for your help!

    I will try to play the charger on the LM350.

Topic summary

The discussion revolves around the feasibility of using multiple TP4056 modules to charge several 18650 batteries simultaneously. Users confirm that connecting the modules in parallel is possible, provided each module's output is not interconnected and that the power supply can handle the total load. Suggestions include using multiple TP4056 chips for higher charging currents and ensuring that the batteries are in similar states of wear and capacity when connected in parallel. An alternative solution proposed is to use an LM350-based charger, which can provide a higher current output for charging multiple cells efficiently.
