It seems that he’s not alone, so he set out to reverse engineer the battery charging circuit to see if there was a fix. Boy is there, what he found is the diode above, apparently installed ...

You’ll need a TP4056 board, providing charging and battery protection features, a jumper, and maybe a pushbutton – the Fritzing diagram shows everything you’d like to know. From there ...

Each component makes something happen using electricity. The picture above shows a circuit with a bulb and a battery cell in. The diagram next to it shows the symbols for each of these components.
