18650 charging box

Overview

I have a lot of 18650 batteries idle in my hands. However, an accident caused the charger to become two and a half, which made my family, which was not wealthy, even more miserable. I couldn't bear to look at the pile of lithium batteries without chargers and dying alone, so I opened a certain treasure tremblingly. However, the charger was too high, so I had to settle for the next best thing, so I bought 10 pairs of these for 6.88.

Since I can't afford to spend a lot of money to buy a charger, I have no choice but to do it myself. I can't help but choose my fate! Start drawing!

Begin violent disassembly and assembly

Seeing that this pile of lithium batteries finally found its home again, the steamed buns and pickles in my hand became even more fragrant.

The charging and protection circuits have not been soldered yet. I will solder, debug and update them when I have time.
