The surgical instrument comprises an end effector and a motor to drive a firing motion at the end effector. The end effector comprises a first jaw and a second jaw, the second jaw moveable relative to the first jaw from an open position toward a closed position to capture tissue therebetween. The plurality of power sources comprises a first power source removably couplable with the surgical instrument and a second power source removably couplable with the surgical instrument independent of the first power source. The second power source is to maintain power to the motor in absence of the first power source. ## Claims ### Claim 1 A surgical system, comprising: a surgical instrument, comprising: an end effector, comprising: a first jaw; and a second jaw movable relative to the first jaw from an open position toward a closed position to capture tissue therebetween; and a motor to drive a firing motion at the end effector; and a plurality of power sources, comprising: a first power source removably couplable with the surgical instrument; and a second power source removably couplable with the surgical instrument independent of the first power source, wherein the second power source is to maintain power to the motor in absence of the first power source. ### Claim 2 (depends on 1) The surgical system of claim 1, wherein the first power source comprises first power cells, wherein the first power cells are connected in series; and wherein the second power source comprises second power cells, wherein the second power cells are connected in series, and wherein a number of the first power cells and a number of the second power cells are different. ### Claim 3 (depends on 2) The surgical system of claim 2, wherein at least one of the first power cells or the second power cells comprise rechargeable power cells. ### Claim 4 (depends on 2) The surgical system of claim 2, wherein at least one of the first power cells or the second power cells comprise non-rechargeable power cells. ### Claim 5 (depends on 1) The surgical system of claim 1, further comprising a power regulating system to control power supplied by each of the power sources to the motor. ### Claim 6 (depends on 5) The surgical system of claim 5, wherein the power regulating system is to control power supplied to the motor such that the motor operates at a substantially constant speed, independent of which of the power sources is coupled to the surgical instrument. ### Claim 7 (depends on 1) The surgical system of claim 1, further comprising a circuit to electrically couple each of the power sources with the motor, wherein the circuit comprises a switch to adjust a number of power cells of each of the power sources to supply power to the motor. ### Claim 8 A surgical system, comprising: a surgical instrument, comprising: an end effector; and a motor to cause the end effector to perform a treatment motion; and a plurality of power packs comprising: a first power pack removably couplable with the surgical instrument; and a second power pack removably couplable with the surgical instrument independent of the first power pack, wherein the second power pack is to maintain power to the motor in absence of the first power pack. ### Claim 9 (depends on 8) The surgical system of claim 8, wherein the first power pack comprises first battery cells, wherein the first battery cells are coupled in series; and wherein the second power pack comprises second battery cells, wherein the second battery cells are coupled in series, and wherein a number of the first battery cells and a number of the second battery cells are different. ### Claim 10 (depends on 9) The surgical system of claim 9, wherein at least one of the first battery cells or the second battery cells comprise rechargeable battery cells. ### Claim 11 (depends on 9) The surgical system of claim 9, wherein at least one of the first battery cells or the second battery cells comprise non-rechargeable battery cells. ### Claim 12 (depends on 9) The surgical system of claim 9, further comprising a power regulating system to control power supplied by each of the power packs to the motor. ### Claim 13 (depends on 12) The surgical system of claim 12, wherein the power regulating system is to control power supplied to the motor such that the motor operates at a substantially constant speed, independent of which of the power packs is coupled to the surgical instrument. ### Claim 14 (depends on 8) The surgical system of claim 8, further comprising a circuit to electrically couple each of the power packs with the motor, wherein the circuit comprises a switch to adjust a number of battery cells of each of the power packs to supply power to the motor. ### Claim 15 A surgical system, comprising: a surgical instrument, comprising: an end effector; and a motor to cause the end effector to perform a treatment motion; and a plurality of power sources comprising: a first power source removably couplable with the surgical instrument, the first power source comprising first power cells, wherein the first power cells define a first voltage potential; and a second power source removably couplable with the surgical instrument independent of the first power source, wherein the second power source is to maintain power to the motor in absence of the first power source, wherein the second power source comprises second power cells, wherein the second power cells define a second voltage potential, wherein the first voltage potential and the second voltage potential are different. ### Claim 16 (depends on 15) The surgical system of claim 15, wherein at least one of the first power cells or the second power cells comprise rechargeable power cells. ### Claim 17 (depends on 15) The surgical system of claim 15, wherein at least one of first power cells or the second power cells comprise non-rechargeable power cells. ### Claim 18 (depends on 15) The surgical system of claim 15, further comprising a power regulating system to control power supplied by each of the power sources to the motor. ### Claim 19 (depends on 18) The surgical system of claim 18, wherein the power regulating system is to control power supplied to the motor such that the motor operates at a substantially constant speed, independent of which of the power sources is coupled to the surgical instrument. ### Claim 20 (depends on 15) The surgical system of claim 15, further comprising a circuit to electrically couple each of the power sources with the motor, wherein the circuit comprises a switch to adjust a number of power cells of each of the power sources to supply power to the motor.
