hi everyone, I'm looking to buy an extended battery for my 3DS(not XL), and was wondering if anyone can tell me if they've had any good experiences with these 2 in particular i've got my eyes on: the CTA Digital Power Grip Deluxe and the PowerA PowerCase, I'd like to get as much gameplay as i can before charging again, also, has anyone had any bad experiences with the bigger capacity packs like this 5000mAh one i've read about? I appreciate any suggestions anyone has, and thanks :)
