  • Probably, as long as the specifications of the motor and the H-bridge are met. Remember a fully charged 12V battery delvers about 12.7-12.8 Volts. Don’t discharge it beyond 50% (3.5Ah). – StarCat Aug 21 '20 at 6:05

Yes, though at 2A you're at the top end of the L298N current limit. Expect excessive heating. You will have to manage your thermal environment appropriately.

You should consider a more capable driver with more current headroom and less heat problems. (Note: the L298N is a very old chip and uses old technology. It's not a good choice for modern drive systems and a more appropriate device should be investigated, for example the MC33931 as the first hit on google).
