Requirements;

1. Battery Charge Controller Card (XH-M603, HCW-M632 https://aliexpress.com/i/1005004109363595.html)
2. 4xM2 screws

Notes Before Print;

1. PLA, PETG or ABS can be used
2. %15 infill enough, main box requires support

Optional;

There is only 1 red led on the normal control card and it only lights up while charging. If you want the red led to turn off and the green led turn on after the charge is finished, you must modify the board. All you need is 1 piece of 3mm green LED and 330R resistor. Connect your led and resistor with a thin cable between the battery negative pole and D3. There are 2 led holes in the main_2led.stl file that I added extra to the files, place your new led next to the red led.
