Hi,
maybe it's a novice doubt but... Is there a battery capacity to be charged through a TP4056 module? can I use this module to charge, say, a 1000mAh battery or a 3.000mAh batteries? In case of "yes", can I use just one TP4056 module to charge a set of batteries in paralel mode? How may batteries can a TP4056 module charge? Or what is the maximum capacity of an ordinary TP4056 module?
(Please excuse if this question is too primary and my not-too-good english.)

Do a Google search for;
'TP4056 datasheet'
The datasheet for the TP4056 will tell you the maximum charge current it is capable of.
A TP4056 can charge at 1A maximum. You can charge just about any li-ion/lipo battery with it provided you set the current accordingly. Many modern batteries permit charging at currents greater than 1C.
There is some debate about charging multiple batteries in parallel. The manufacturers rarely recommend it. However after some testing I'm happy parallel charging my own lipos, even lipos of different capacities (though obviously the voltage/number of cells must be the same). But I'm careful, I know what I'm doing and it's still possible to get it wrong so I'm not going to recommend parallel charging to everyone.

Thank you, srnet.
I've found this datasheet: https://dlnmh9ip6v2uc.cloudfront.net/datasheets/Prototyping/TP4056.pdf
But I'm not sure I've understand that properly.
"Programmable Charge Current Up to 1000mA"
It means the maximum current provided by the module to charging the battery(ies) by the TP4056 CI OR the maximum the battery(ies) fully charged can provide to the circuit feed by the battery(ies).
And now occoured me another doubt: if 1A is the maximum provided through TP4056 to charge the battery(ies), is it 1A the maximum provided to the circuit AFTER the battery(ies) too?
I'm asking that because when the circuit feeded by the batteries I've built can ask more than 1A. Actualy it's a PWM sound amplifier (class D) wich can took, when the sound are louder and full of basses, even 1.5 or more amperes. And beyond that amp I have also a player, wich, as in the specification paper is said, takes something between 0.5 and 1A. (USB reading takes more than FM receiving, for example).
Thank you, Steve.
I'm using two TP4056 to charge two 18650 batteries, both connected in paralel but I'm not sure I'm doing right. My idea is double these circuits in order to avoid overcharging each one (and with hope it can divide current as they work with the same tension, voltage).
But recently I've noticed a person uses just one TP4056 module with a REAL 3300 mAh battery without problem. Well... the batteries I'm using says it can offer 8800 mAh (I've discovered too late it's impossible, probably it's manufactured in some sort of shady company).
Now I got 2 Samsung original batteries wich says can provide 2200mAh each. And as I'm remaking the gadget I'd like to do the right thing.
Some told me it's better to buy a real BMS board. The problem is that this units are rare in my country, Brazil (as rare the good batteries too). And beyond that, these real BMS boards don't have a LED to indicate the batteries state, like the TP4056 modules have.
Yiu said you charge mor than one battery with just one PT4056 module. How many batteries? Can you recommend how much mAhs can I charge with just one TP4056 board? And what do you think about double-ing the charging scheme, as I did first?
rmlazzari:
"Programmable Charge Current Up to 1000mA"
You asked what the charge current the TP4056 can provide and as the datasheet says its 1000mA.
The TP4056 IC does not care much if its connected to a 1000mAhr battery or a 5000mAhr battery, the maximum charge current it can provide is the same although the larger capacity battery will take longer to charge of course.
rmlazzari:

Your confusing charge current and the capacity of the battery, not the same.

Thank you. I've answered me when you said

I guess it doesn't matter if it is just one 4400mAhr battery o two 2200mAhr in paralel, is it right?
But now, thinking about using the device connected to the charger in the wall, when the set player+amp asks more than 1A, isn't it problem for TP4056, as something in it is between the set and the charger?
The charger is rated to provide 3A.
The TP4056 can charge up to 1000 mA. The actual peak charge current is set by the value of the resistor "Rprog" on pin 2 of the TP4056.
The peak charge current should be set so as not to exceed the maximum charge rate of the battery. This should be specified in the data sheet for your particular battery.
The peak current out of the battery is also a function of the battery and should be specified in the battery datasheet. Some LiPo batteries allow very high discharge rates, particularly those intended for use with quadcopters and such.
I guess it doesn't matter if it is just one 4400mAhr battery o two 2200mAhr in paralel, is it right?
Yes it does matter, only connect use and charge, LiPo batteries in parallel that are of the same type, charge state and well matched. Some will suggest its OK to take a chance, risk your life\shed\house and mix and match LiPos in use and charging, I dissagree.
But now, thinking about using the device connected to the charger in the wall, when the set player+amp asks more than 1A, isn't it problem for TP4056, as something in it is between the set and the charger?
Again, the TP4056 neither knows or cares how much current a project is drawing out of the battery, it can only supply 1A into it.
Actualy the batteries I'm using are Li-ion, srnet. But as I'm not specialist maybe it's not different of the LiPo ones.
And about double-ing the modules TP4056 in paralel... is it waste of money, is it good, bad, nothing... what?
I confess sometimes I think about these modules as it were ICs...
Hello,
Most of the battery can be recharged with 11% of the nominal value for 15h, this is known as slow charging. [Valid for batteries such as Ni-Mh and Ni-Cd]
For faster recharges, it is recommended to see the battery's datasheet.
The TP4056 should be very hot when operating at the limit, 1A, I noticed that when using 5V at the input, and the PROG with 5k ohms, 250mA, the TP4056 should warm up very little. Hot operation can cause irreversible damage in a short time.
It is also recommended to use the battery protection,
There are boards with TP4056 + Protection:

Very dangerous advice! This does NOT apply to Li-ion/Lipo batteries. They need a specific Constant Current/Constant Voltage (CC/CV) charging method, generally at 0.5 to 1C.
What you suggest will overcharge the battery by more than 50% and is likely to burn your house down. It is a method that can be used for charging Ni-based batteries only (NiMH/NiCd). Definitely NOT the Li-ion/Lipo batteries that we are talking about in this thread.

Can you delete or revise your post please, that is very dangerous advice ?
Ok
What do you think? Was better explained?

I have several emergency luminaires with 18650 batteries, and they are recharged with approximately 25mA constant, and have only one voltage limiter with the TL431 IC to not rise beyond 4.2V. They've been running for years.
There are normal and protected 18650 cells.
The protected cells have an over/under voltage/current/temp protection circuitboard buildin.
Safer, but still not wise to charge them with a constant current.
Leo..
