I'm looking for a small but has high capacity battery.
At least the battery should have more than 10000mAh and any voltage would be OK.
As far as now, Lithum Inorganic battery(TL-5930), was the best that I found but its size is too big for usage.
Is there any smaller than that battery?
Or is there wany way that I can re-make using Li-ion battery?
I don't know how to get more than 10000mAh (unless you want to wire home phone batteries in parallel, an average one is about 1000 mAh) but, those batteries do have high capacity for obvious reasons, just an idea
