Gamecube Battery Circuit

So like this is the first time that I have ever attempted implementing any form of rechargeable battery packs into a project along with a charger port. So for a short run down, I am not sure if I got the diagram correct or not.

Oh and just ignore the connection between B3 onto the PCM B3, I know this is wrong...I think.

Also, I was also wondering if this set up won't destroy the board itself. I am using an uncut REV C board and I also read that the maximum mah it can take is around 6800. So if that is the case, then I will end up changing my choices around.

Not sure what you're saying about it only being able to take 6800 mah... The board (or any electronic) will only draw as much power as it needs and function correctly (given your input voltage is correct obviously)

As for your pack, I wouldn't go with 11.1v as the voltage output of a 11.1v battery near the end of a charge cycle is lower than the cut off voltage of the cubes regulators so you'll never get full usage out of the pack so it's mah rating of 9000 you're wanting will be pointless.

Go with a 14.8v pack if you're wanting to use the stock regulators

If you want much better efficiency and the ability to use 7.4v packs, look into Zenloc/LOCtronics guide about custom regulators to power the main chips off of located in the GC Mega-Sticky.

You answered what I was mainly concerned with, thanks. I will also look into what you said about the 7.4v packs.
