Got the
PR-2310 in the mail today. It's all charged up and ready to go. I was surfing the web for a couple hours on my X51v today, so the batteries around 55%. It's turned on and I'm getting ready to plug it in...
Bam! No flickering! The screen brightens up the way it should and the axim recognizes it's charging.
So the ~$93 battery pack does what it's supposed to do. I'm thinking the smaller battery pack for the PSP isn't cranking out enough amps. Oh well, I'm sure I'll find some use for it.
I was looking at the Tekkeon packs. I like the form factor better, but I'm still wary of buying Li-Poly batteries because of their limited number of charging cycles. I'll stick to the Li-Ions until the Li-Poly technology gets better. I like keeping my batteries topped off and Li-Polys don't last long doing that. As for the larger battery size, 36 Wh versus 40 Wh isn't going to lose me any sleep... although, had I ordered a Tekkeon, I'd probably pick up the bigger 56Wh one.
