Yes you can. I do it. Have a setup with .5 ohms quad
coils. That battery should do fine. You could go as far as .15 ohms with that battery. Someone just told me that the Efest specs are over rated so apparently they are only rated to 20 amps. So apparently the lowest you can go in resistance is .21 ohms. As a matter of practice I never hit the max on batteries. Because if your ohm meter is off by a small amount you could have a bad day.
