I'm trying to figure out the cell setup for my Ryobi P108 battery. anyone here knows the parallel and series configuration for this battery? Any help would be awesome
 
Ryobi P108 packs usually have a 3S2P setup, three cells in series, two in parallel. That gives about 10.8V nominal voltage with doubled capacity, I hope that helps

There might be a confusion here.
The Ryobi P108 18V Lithium+ battery typically uses a 5S2P cell configuration.
This means you have 5 lithium-ion cells connected in series to achieve the 18V nominal voltage, and two of these 5-cell series strings are connected in parallel to provide the 4.0Ah capacity.
So in total, there are 10 cells inside.
