I've been considering getting this to start a gamecube portable: http://www.amazon.com/gp/product/B008G2ZX42/ref=ox_sc_act_title_3?ie=UTF8&smid=AHU3RYV04X2FP
It's a universal laptop battery that can output 5v, 16v, or 19v with 5500mah capacity. It charges by using any ordinary laptop charger it looks like. Plus $33.99 shipped!
Has anyone ever torn this apart before or used something similar? I know the gamecube regulator can take upwards of 20v and still work correctly (thanks zenloc!
). Plus the higher voltage should decrease current draw right?
