Found: 1100mAh (0,5mm thicker though)

Specs: http://ecksteinimg.de/Datasheet/LP52346 ... 161116.pdf

same manufacturer as the Adafruits cells.

@Wermy: What's the runtime for the 1200 mAh pack when BT and WIFI are disabled?
Thanks

I'll run some tests this weekend - been meaning to do that for weeks anyway.

Perfect, thank!

I'll buy it anyway. More than 2 hours is overkill for that small pocket device anyway. Guess you can't play with adult hands more than 1 hour before cramping

my guess is 3-4 hours, with everything on!!

Alright, so I tested this weekend using a 2.4" screen. Got right at 3 hours out of it. This was on a non-W RP0 (all I had soldered up to a screen at the time), but this should be a good approximation of using it with wifi/BT disabled. From what I'm reading online the W only uses ~20mA more, so I'd estimate that to put you between 2.5-3 hours with wifi on. Not earth-shattering but for a mint-tin-based gaming handheld I'd say it's alright. And hey, it beats the Switch's battery life when playing Zelda Breath of the Wild.

Also, there is a chance that using the custom PCB for buttons has freed up enough space that a 2000mAh battery is an option. That should put you up around 4 hours. I'll know for sure once I get the final set of parts here and can put one together using it.

Is there a way to enable/disable the Wifi / Bluetooth via Retropie (with a custom shell script or somesuch?) to save some battery life when it isn't needed?

http://www.ebay.com/itm/TZUMI-POCKET-JU ... SwtGlZEUc9 the li-po I pulled was 60.8mm x50.9mm x9.2mm at 4000mah

9.2 mm might already be too thick to fit

Yeah fits great without all the additional guts
