tp4056

I'm working on an outdoor LED lighting project. It just basically works as a motion detection light (turns on when movement is picked up through a PIR sensor). The amount of LEDs I want to use brings the power consumption to 7.2W (12V, 600mA), but the LEDs will only stay on for 20 seconds per...

Hello everyone. I would be very grateful if you can help me with this circuit I am working on (sch.png). It consists of a TP4056 charger connected to a 3.7v/3Ah Lithium Ion battery to supply a low battery level indicator and a load (a block of white leds and two fans), through a MT3608 Step Up...

Greetings. A vendor selling TP4056-based 5 V charging modules for Li-ion cells specified the following resistance values and resulting current for selecting the current-programming resistor: R (kΩ) I (mA) 30 50 20 70 10 130 5 250 4...

Hi everyone, I plan to build a high capacity 3.7V/5V solar charging powerbank (something like 10-15ah). I’m going to use modules of TP4056 breakout board each coupled with two 18650 cells in parrallel. But I was wondering what would it need to charge two or three of these TP4056 modules with a...
