Close, but if each cell is only 2200 mA-hr (i.e. 2.2 A-hr as stated by the OP) then putting 4 rows in parallel will only get you 8.8 A-hr - so still a bit shy of the OP's desired 10 A-hr rating. 5 rows in parallel where each row has 10 cells in series would give you a battery pack with an 11 A-hr rating.
