so i modded mine =)
i dont know if it is electricaly correct... i just tried it that way... the only thing i tested, before plugging it into my switch, was the voltage on the dataline so i dont fry my switch. everything works as it should. I can upload new payloads via usb, the lithium ion cell is charging when connected to a pc. i didnt made a lot of durability testing but i will try to monitor every 3 or 2 days.
i connected the INPUT pads on the charger pcb to the both test pads right next to the micro usb port of the rcm loader. if you look from the front the left pad is + and the right pad is -. i unsoldered both capacitors and left the inner contacts blank as they are connected to each other because of the capacitors are placed in series. the other two pads are connected to the OUT+ and - on the charger pcb as printed on the circuit.
the next thing i will do, if i can get some time, is designing and 3d printing two more of those colored side things.
