I'm making a circuit to control two motors and now i am using a 6v motor, and as the datasheet of the l293d says, we'll get a typical 2.6 voltage drop across the output pins right ? So if i put a 7.4v battery, it will receive 4,8, which is not a very good value. There are 8.6v batteries and 8.4v in the stores, but for me they're really expensive, i was looking for an alternative way to get around 5.5-5.8v in the motor with a 9v battery that is cheap, can you guys help me ? The diagram i have for now is this one:
