I have a few, thin, small, Li-Ion batteries that I purchased (surplus) that I never had a use for -
AND
they are two terminal - so I think they are just storage cells (no management controller inside).
They might have been for some sort of RC rig.
I haven't seen the tablet's battery yet - I will see that when I see it.
but it is hard to imagine that its battery will be smaller than these.
