So I took this fan and wired it to run off of battery. Testing it before I did this, it blew the fabric "flames" perfectly fine. After the rewire, the fan seems to blow the same but my "flames" don't move now. Any suggestions? I tried a second battery (ie, two at once to bump up the voltage), double checked that the fan is the right way up and that there's enough room for air flow underneath the fan already. We're going to try increasing the ampage next, I guess...?
