Powering Arduino Uno Using 7.2 NiMH Battery

I am trying to power my Arduino and two 5V DC motors using a 7.2 NiMH rechargeable battery and I want to make sure this is doable before powering the components.

This is the link to the battery I am using: https://www.amazon.com/Venom-3000mAh-Battery-Universal-Traxxas/dp/B00FE10JEC/ref=sr_1_9?ie=UTF8&qid=1510173766&sr=8-9&keywords=nimh+7.2v+battery

And I have bought a barrel jack connector to connect the battery into the Arduino.

Is this doable? Am I missing something?

Thanks.

Powering the Arduino that way is fine.

But what are you intending to connect the two motors to and what sort of motors are they and how are they controlled? Powering motors from the Arduino 5V pin is usually a very bad idea unless they are very small low current motors. A diagram showing ALL your planned connections would be useful.
