Imalent ms03 making high pitch sound

Hello, my imalent ms03 is making weird high pitch sounds, around 15-16kHz when on. It gets louder during higher power draw. What’s causing this? Are the leds about to go, or does it have anything to do with the drivers? It’s annoying, but also I didn’t notice this when it was new, so i’m wondering if something’s wrong with either the flashlight itself, or the imalent battery circutry which would be scary (it’s one of those batteries you charge by plugging a usb directly into the battery. I somehow doubt it’s the battery, but figured better to ask)
