Use Cell Phone Batteries to power a Nintendo?

[ihakr]

I'm still trying to get good, cheap ideas to power my pN64. I came across the Chinese made extended batteries that are made for the HTC EVO 4G with a charger that doesn't require the actual phone to charge the batteries. The batteries work very well for my phone, and they have 3500 mAh and output 3.7 volts. So I could wire two up to get 7000 mAh and have 7.4 volts and have a charger. I am wondering if there are any obvious problem to my solution to my battery problem.

Here is a link to the Batteries

It doesn't work that way. You can either add voltage OR Ah. Not both.

Buy this if you wanna be on the cheap: http://cgi.ebay.com/2-x-Canon-BP915-Bat ... 1584wt_910" onclick="window.open(this.href);return false;

It will get you 4000mAh at 7.4v if wired in parallel.

You would need 4 batteries to get that voltage and capacity.

Or you could just live with 3500mAh. That's still like 2 hours.
