Hi everyone,
Am using a vacuum pump in my project; it’s 12 VDC operating on 12 W… This is the one:
I wanted to switch on/off the pump using an arduino UNO.
Here are my questions:
Is this motor driver the best one to use…?

Also, do I have to use lithium battery or there are alternatives?
Thanks a lot…
If I were you,
I would just use a transistor, a couple resistors, and a diode. Just make sure the transistor can switch the current of the pump.

A good start
Like Max and Bird mentioned this is how I would try it too. Needs soldering. Use a digital output from the Arduino to trigger the NPN. Make shure you take a NPN that has an adequate Max Collector Current specified in the datasheet.
Shure you could add a 403 capacitor between the pump + and -. But the schema above is a good start.
You may also have a look at this project . It uses a motor driver. Look in the Further Readings section.
