battery for L293D driver (2 dc motors)

[tomas]

I have 2 questions about L293D:

1. If Im using for L293D supply 11.1 or 7,4 volts battery (something like this https://propeleris.lt/zippy-1300mah-7-4v-15-25c-lipo-akumuliatorius.html ) and for microcontroller 9 volts battery, can I connect L293D and MC to the same ground, o should i separate them?

2. I need to control 2 dc motors with L293D. Is this battery will be enough for both motors? https://propeleris.lt/zippy-1300mah-7-4v-15-25c-lipo-akumuliatorius.html

thank you for your time and answers I think these were quite easy questions, I just want to make sure I'm doing my project right

What is the voltage you are giving to L293D and the 2 motors? How long do you want to run the motors? How much current does each motors draw? Are you going to charge the battery without removing it from the circuit?

The battery can only give 1.3A continuously for 1 hour. If one motor draws 1A to run then the motor runs for 1.3 hrs. The battery is 7.4V and your motor is 12V. Are you sure your motor runs from 7.4V?
