Hello everyone! I'm new here (started in the Bitfix forums), and am working on my first portable, a Gamecube portable. I know everyone will tell me "build a Wii, it's much better," but I want to see this project to the end as I plan on doing a Wii portable second, using the knowledge gained from this project on my next one I've done a bit of research, and am currently working on what battery I need to run the whole setup. Currently I've been thinking of setting up a 14.8V 18650 Li-ion cell structure, but I'm wondering how I would set this up with this charge-and-play circuit: https://www.batteryspace.com/cmb-fo...ck-10a-limit-rohs-compliant-with-dc-char.aspx I want to have around 5000mAh in capacity, which by my understanding is a 4s2p setup - how would the 8 cells be wired up with that CMB? can it support 8 cells? and what/how many cells do I need to get (the 3.7v Panasonic cells in the BOM?) /how would I wire them up for this purpose? If the CMB doesn't support it, I am willing to step down to a 4s1p setup, but this wouldn't provide as much capacity. Because of a lack of availability of tools (I don't have a bench power supply at my disposal), I haven't been able to test my screen for voltage and such. It's an RCA DRC69702, a screen taken from a DVD player set that accepts composite in. It runs off of 9-12V DC. Would it be able to handle 14.8V? could I run that off of the 12V power rail on the GameCube, or should I just run it off the battery? For additional details, my GameCube is a Revision C motherboard with the built-in regulator. I've read it can handle 14.8V, but my main question is how would I wire this up? I want to make sure I have everything right in order to not fry my Dolphin. If I have any more questions unrelated to batteries, I plan on starting a worklog soon, so I will post them there. Sorry for all of the noobish questions, and thanks for your help!
