DX6 iCharger Buzzing
 

I'm getting an odd buzzing noise from my new DX6 charger. I returned it back to Hobby town and exchanged it for a new one. The new one is doing the same thing. I took some video of the issue.

so we need a bit more information

When exactly is it buzzing? When you connect to power and nothing is happening or only when charging? the video shows you are charging.
If the X6 is only buzzing when charging, is it all the time regardless of amperage or if you lower the amperage the buzzing minimizes?
Does changing the Lipo S count increase or decrease buzzing?

It starts buzzing after a couple minutes of charging. I charge 2s packs it doesn't matter if I'm doing it on channel 1 or channel 2 I still get the buzzing. I charge at 10 amps. I will also get the buzzing when I discharge at 20 amps. It only seems to happen after the charger is been doing whatever I have it doing either discharging or charging after a couple minutes it will start buzzing.

Mine does the same thing. Sounds identical. I believe it’s the fan when it gets warm and hits the higher RPMs. If you have had two and they both do it as mine does I’m gonna say it’s normal. It’s annoying in a quiet house but can’t hear it at the track with all the noise. I’ve wondered about mine as well.

Thanks for confirming. It's odd to me to have a "high" end charger mage this noise. The S6 I picked up used is quiet as can be even with fan nose. Hobbytown had another replacement sent. I thought about cancelling that and going with the 456 Duo. Junsi's support was no help.
