Hello everyone,
I have bought this battery charger (https://fr.aliexpress.com/item/1005002208969387.html?spm=a2g0o.order_list.0.0.29c15e5bLHOiY5&gatewayAdapt=glo2fra ), I can charge correctly my battery. However, I don't have anything going outside of my board if I plug a usb cable, I can't charge my phone. (no voltage in the USB pins)
Here is what it looks like now:
Any idea why it doesn't work, why I don't get anything? I have checked the voltage out of the battery, I got 3.6V, and I got 5 amps, which is reasonable given the fact that they are old batteries, and plug in parallel.
Is that a push-button on the left end of the board to turn on the outputs?

Hello John,
Yes but, but when I plug something into usb, the LED shows output, but I don't get 5V as output in the pins.
It sounds to me like your device is defective. I wish I could help more.
Those four cells are in parallel ?Bad idea.

Bad
Why is it such a bad idea, it is just that if they do not have the same age?
The current does not divide equally.
