Learn how to assemble a custom battery for PSP.
Tutorial created by Edgar F. Diéguez
Clean the battery board by removing all components except the connector. Scrape the voltage, ground, and signal traces to expose the connections.
Remove the headers and ports from the module. Bridge the 5V headers to ensure a constant output.
Bend one leg of the 1n4148 diode into an 'L' shape and solder a wire to connect it to the scraped trace on the battery board.
Solder wires for VIN, GND, D+, and D- following the indicated schematic.
Connect TX to the end of the diode, RX directly to the central pin, 5V to the left pin, and GND to the right pin.
Adjust the case to fit the USB-C port. Use hot glue to temporarily secure the pieces.
Place the boards inside the case, ensuring no short circuits occur.
Secure the case with adhesive tape.
