I'm building a custom Nintendo Gamecube handheld portable. I want to use a 7.2v 4500mA Lipo battery. I have found out that the gamecube mobo needs three different voltages. those voltages being... 1.9v at 6600mA max, 3.3v at 800mA max, and 5v at 350mA max. I calculated that the gamecube would consume 2270mA at 100% efficiency (which we all know is almost impossable). I would like to know how many mA the system would consume at say 55% efficiency, because I haven't found the math formula to figure it out. I would be very thankful if anyone can help me out.
