Question An inquiry about batteries

[NLG]

I am completely lost on how to make my portable wii run off of batteries. Ive got a total of 12 li-ion cells from laptops that I can configure to have 12 volts, but how on Earth can I charge them? Whats the easiest way that won't turn my wii into a bomb?

Thanks
