Please check Roomba Discovery's H bridge is it using the two 2SB772 and 2SD882 transistor pairs, the 2SD882 have max currents of 3A, so if it used two will be 6 A max then it can drive two motors of 4A.

Yes after posting i was looking at that and it indeed dose use two of the 2sb772 and 2sd882 transistor pairs.
Would that be the total for the h bridge or would that be on each side because my roomba has these pairs on each side of the motherboad. So it looks like there could be two h bridges one for left and one for right sides.
