TP4056 Led Headlamp Charger Modification

While I was thinking that there is no worse, dangerous, low-quality design for 18650 Rechargeable Li-Ion batteries and chargers, I encounter much worse chargers and batteries. The batteries of the LED Headlamp are completely dead, the charger is extremely low-quality and weak, so I placed a TP4056 module in the charger so as not to waste new batteries (from laptops).

The TP4056 module has a USB type-c input, and many phones already use a type-c charging adapter. First of all, I strengthened the solders of the USB socket. Even if the TP4056 card is zero, the USB solders are weakened.

Then I made the TP4056 cable connections and covered it with macaroni, it is not necessary, but I added a cooler to the TP4056 module.
