3S Li-ion Charging Module: Find a Suitable Module for Charging 3-Cell Li-ion Battery Packs

Question

Hello, is there a module thanks to which I will be able to charge a pack of 3 li-ion cells?
I found one, but I'm not sure if it has charging options (you can't see any LEDs indicating the charge level).

Hello I suggest visiting the site I believe that the information contained therein will be the answer to the question posed.

There is a LED description on the board, it looks like two LEDs, probably to indicate the charge status.

Unfortunately, this arrangement will not work. For it to work properly, each TP4056 module would have to have a separate 5V power source or the switch used had 2 sections so that, in addition to plus, it also switched minus power supply. Power cons and pluses cannot be directly connected to each other permanently.

Hello. From what I know, no specialized charger is required for this module, its basic requirements are appropriate current efficiency and voltage not exceeding 12.6V. Best regards.

gumisie · Accepted Answer

From the specifications on the page I gave it follows that yes, in my opinion, there should be no problem. Best regards.

Thank you for your answer

The catalog card says:
Technical parameters:
Voltage: DC charging voltage: 12.6V CC / CV

I am not sure if I understand correctly ...
So the module has cell charging options yes?
In that case, how do I know when the loading process has been completed?

darkmoner · Answer

Now I just noticed ...
The specification sent by "zbigniewsk" concerns another module.
What does it look like with my module? He has only understood the protective function so?

Why is P- and P + signed as "charge"?

kwazar · Answer

How is that why? After all, you connect the charging adapter and load there. The system is a safety device against overcharging during charging, and against excessive discharging with connected load.
He keeps an eye on the battery.

My only contact with li-ion modules is TP4056. I connect 5V there and I have everything somewhere, because the module will fully charge the cell for me. In this case, if I give 12.6V from a power supply, will the module do everything for me?

goldi74 · Answer

This system is only or until the protection of individual links of the packet against overcharging and excessive discharge. To charge such a package you also need a Li-Ion 4S charger.

darkmoner · Answer

Thanks for any help, maybe you know some cheap and good module of such a charger? I prefer to make sure you meant 4S or 3S?

goldi74 · Answer

Of course, 3S, e.g. such a charger: An example for fast at a not too low price, you can find cheaper.

darkmoner · Answer

I understand, I have one last question. Could such a scheme work correctly and safely charge the cells?

darkmoner · Answer

So having this module and giving on P-, P + voltage 12.6V I can charge the cells freely yes? :about

darkmoner · Answer

In that case, thank you for your help

@gumisie Zajrzyj do noty katalogowej układu scalonego to zobaczysz, że to układ zabezpieczenia ogniw, a nie ładowania.

gumisie · Answer

Layout, layout, module, module. Buddy, what do you think the protection of links is . Read and understand the specifications of this module. and do not provide links to any page from which there is a problem. Best regards.

LED5W · Answer

@gumisie I corrected the link. Protection consists in cutting off the cells when the voltage or current exceeds the permissible values. There is no other system there, so what do you think, what is the limitation of the charging current in this module? And where is the charging current in this specification?
