I'm going to be building a convertible tablet using the A320TM-ITX thin-mini itx motherboard to create a desktop tier convertible tablet like the TC1100 and I think I know how I'm going to put everything together, but there are two things I'm not sure about, which are how to get the TC1100 keyboard to connect to the device (a question for another time) and how to get it to run off of a battery power supply. From the looks of the motherboard, it appears to have two outlets/inlets of power, which are the P4 MB connector and a DC power jack. My first though is to find a power bank of some sort that is relatively flat that has a P4 MB connector to power the motherboard (and possibly GPU) and use the DC jack to charge the battery through the motherboard. However, I'm unable to find any such battery that is short of someone having just strapped a car battery to a PSU, which is obviously less than optimal. Another possible option is using a Pico-PSU and connecting the 24ATX end and plugging it into a battery and then plugging one of the modular cords into the P4 MB (and maybe GPU, once again) and using the DC jack to charge, like the earlier solution. However I still can't find any battery that has a 24ATX connector either. I feel simply that I am stuck, any suggestions would help, thank you
