2007 Seadoo GTI 155 SE

I installed a dual battery in my Seadoo with a dual battery switch and all works great. My question is about the vent tubes. I put a T in the line and ran a vent tube to each battery. When my Seadoo is sitting in the carport with the battery switch off, I hear a chirping sound that comes from the exterior battery vent tube exit hole in the hull. Any thoughts what it may be?

The T is more restrictive than the hose speeding of the airflow thru the fitting maybe causing a whistle effect or your chirp.

Thanks. Is there anything I should be concerned about?
