Well I just ordered this battery:
The sizes are 3,8x73x125 mm. This should well fit even with the original screen.
No idea about the quality but somehow the well-known brand battery makers simply don't seem to bother with Lipo "tablet" like batteries ? At least I couldn't find any....so we'll see how it goed. At least this one has a protection PCB built-in.
I figured I could go with something crazy like a 10000mAH battery but who needs a Lynx that can run over 24 hours without charging ?
OK it would be fun but there would be some disadvantages:
- weight. I saw one of the 10000mAh batteries weighed 200 grams. This would be quite a bit more than what a set of 6 AA Nimh batteries would weigh (6x26 grams= 156 grams) and remember that my speaker is already a lot heavier, plus there will also be the Powerboost board, although that is not much....but still.
- charging time. The bigger the battery, the longer the charging time....simple. Of course you don't have to do full charges/decharges on a lipo, but still...
- size. Even if it would fit JUST right...why bother, why not keep some nice space for air to move a bit.....
So I figured 5500mAh would be plenty.
It will take a couple of weeks to arrive with Aliexpress as I have experienced with all my orders so I still have plenty of time to get the Powerboost 1000C and a nice fat wall-charger with micro USB connector. And some time to figure out how I will fit he Powerboost inside. Would be nice if I can use the micro-USB port directly.
It would be cool to add a multi-colored LED somewhere to replace the original LEDs on the Powerboost board, so that the status of that one (power-on/ power low/ charging etc.) is visible at all times. Don't think I'd put it on the front of the Lynx though but f.i. at the top.
About the brightness/contrast pot: remember I'm planning to use that one (or at least the spot and wheel) for a pot to control the clock frequency mod
