Dual Powerlab 6 Touch audible noise from choke during charging


Hi!

I got a new Dual Powerlab 6 Touch and after getting "Lost Data Link Error", I added Clip-On Ferrite Chokes to the cable.

One big near the Powerlab with positive and negative wires going through and two smaller ones near the power supply (one for each wire).

I started Charging 2 3S 5000 mAh Lipos (1C) and the one near the Power Supply on the negative line made an audible noise.
You can hear it in the attached zip-compressed wav file.

The audible clicking remained after switching from a 25V Power Supply to a 24 V Battery. That leaves the DPL6 as the source.
Is there something that can be done about it?
