Increasing Current Output in TP4056 Chargers: Parallel Connections and LED Control

Hello
I have some questions about Li ion battery chargers.
1. Can I increase their current output per OUT by connecting the chargers in parallel?
2. Can I "pull" 3A by connecting 3 such chargers in parallel with OUT?
3. Will the cells (3 connected in parallel) charge in the same way?
4. Can I solder to one module and lead wires to the LED to control the battery charge level or do I need to put several AND gates there?

The TP4056 circuits themselves can be connected in parallel, there are such ready modules: https://www.elektroda.pl/rtvforum/topic3036268.html#15576657 I am not sure just how the case with the security system will look.

Hello forum users!

I have a similar discussion regarding connecting two converters for charging Li-Pol battery with booster function.
I am interested in a specific model
https://www.tindie.com/products/ceech/lipo-ch...converter-5v-33v-outputs/?pt=full_prod_search

I want to connect 2x8000mAh battery power inputs and power the Raspberry + display simultaneously.
Raspberry is supposed to work non-stop, and the batteries are to be charged or discharged depending on whether they are used or not.
According to the designer, the max battery charging current can be set to 2A and the max 5V supply current can be set to 1.2A.
For me, the desired current for 5V is a minimum of 1.2A, so I want to connect them in parallel with 2 converters.

The DC power supply would be made with a 12V 2A charger (for one converter) where the converter would also handle this current and voltage according to the designer.

My question is whether there will be different potentials on the 5V power contacts and can I connect the batteries in parallel or separately for each charger?
According to all information from the forum and my knowledge it should work but I would like to confront this knowledge with advanced users on the forum
As for me, the best for batteries would be to connect them in parallel and parallel connection to both converters. Then the charging current would rise to 4A.

Regards!

Hello
I have some questions about chargers ...

Ad1 Ad2 already got the answer in post # 2, those in the picture can not be combined in parallel.
Ad3 Yes
Ad4 write something more if you want to implement it and when this measurement would be.

Damn, now I have a problem ...
I need 12v power supply and 3A efficiency
I wanted to charge them with the charger that is in the post. But the output current output (OUT) is only 1A.
How can I solve this?

Did you see this or this ?
