Yes, a low battery will cause additional noise for sure.
if the red light goes on and off again right after you turn on the
switch, the battery should be okay. They don't last that long,. maybe
24 total runninghours?  use alkaline bats only.

you should be able to make good recordings with that gear (assuming
humidity is not causing the noise).  The insects should be louder
than the noise from your mics I'd guess,..

moisture interference often sets on like a low sputtering fizz with
rises and falls, low in volume at first but it should grow louder as
the humidity takes great effect. it its constant noise, check your
mounting situation.

Have you got a shock mount? Most condenser mics are very hard, if not
imossible to hand hold without creating noise. the cable dangling
will make noise.  A  zeplin/windcsreen is also needed even in the
slightest breeze. throw away that foam thing they give you. its
worthless against wind with that mic. The rode manual is very explcit
about how to equip the mic for use outside. You'll get better
results, somehow. Rob D.
