common source or commond drain battery protection?

Good morning,

I'm designing a new BMS for a Li-ion multi-cells battery pack. I would like to use a dual n-channel MOSfet for braking the current flow both in charge and in discharge and I can use them on the negative path or positive path (with a proper gate driver).

So far I've used MOSfets in a common drain configuration because they are commonly used in such a protection circuits, but it is not clear to me wich are pros and cons of both commons drain and common source configurations:

Can anybody help me in understanding characteristichs and features of both configurations, in order to chose and test the best one for a BMS, please?

Thank you and best regards

Matteo
