tablet has two batteries ??

I have a Pipo S1 pro and it won't hold much charge of late.
I ordered a battery that looked OK and has
Built-in protection circuit PCM for prevent over charging or over discharging.
When I open the tablet it has two batteries connected to a small thin PCB which is I think the PCM circuit.
One is a normal sized battery and one quite small.
Not sure how my new battery fits in ?
Thanks
Jim

I'm no expert but I think my first tablet had 2 batteries because there was no space, they just stuffed 2 in and connected then to appear as one on the system.

Pictures might help though so someone who knows what's what might be able to point you in the right direction.

Picsattached.
There is the large 3.7v battery on the left attached by foil to the thin PCB
Then the small battery approx 1 Inch x 2 Inch attached by wires to the thin PCB
The thin PCB then connects to tablet via red/black wire.
