Cable noise with battery

[Gianni]

Ciao, has anyone detected a noisy cable with the battery mounted?
The noise comes from the head area of the battery, if it is removed the noise disappears

Hello, I noticed the same when testing a rail 7 (small and large).
I guess the noice comes from a not 100% fixed battery (I could reproduce the notice by pushing the battery (headset region).
There's a fix on YouTube and a pdf for the locking system.
