Sony PSP 3000 or G0 Battery Questions

[Danny McGee]

2 things.

1. Which is better 3000 or Go?

2. I'm thinking of getting one of the above for my road trip to the euros. Now im fully aware that the battery WILL go flat on the trip so am thinking about making a lipo pack that has much more mah than the 980 / 1000 they have. Only issue is im not to sure how to go about it.

Any ideas? I know they are both 3.7V so im assuming 1C which is fine, but is there a way to limit the power somehow and if so teach me.

Cheers

Danny
