KS16S “ticking”after being charged

Recommended Posts

Is it normal that you hear a ticking/dripping sound after the wheel being charged?

At first I thought the sound came from the charger but then I realized it came from the wheel.

I’ve never noticed this before. 

Any suggestions what it is? Is it still safe to turn the wheel on and ride?

Nope, thats not normal...never heard of that.

But it shouldnt be a problem to turn the wheel on. The BMS has under and overvoltage protection and some more....

I assume you talk about the wheel being off and still making a noise?

My KS16S makes a ticking sound if I turn it on and leave it against a wall. Not sure if this is normal.

Yes, I think it went on for two-three hours. 

A strange dripping ,popping, bubbling sound. Not loud, I could barley hear it from 1meter away. 

I will ride it to work now in the morning. Hope everything works as it should with the wheel.

can you give some more information
- How old is your wheel?
- How Many KM's?
-When did these sound start (just bought it, first charge?)
-And what kind of charger your using.

 a dripping ,popping, bubbling sound sounds alot like a leaking battery. this could mean it is getting overcharged.

I bought the Wheel in April and I have ride 95km. I use the charger that comes with the EUC. I use to charge the battery when its down to 30-40%. This is the first time I notice this sound.

That's a sound my Gotway wheel produces when on. When you turn the wheel on at the place where you charged it, it has a different sound?

This sound is when the wheel is off.

I Dont want to sound alarming, but if i were you i would contact the supplier ASAP

It is, like Ulf stated, not normal, i would personaly open the wheel up and try to locate the source, i mean if it is from the board, its probably just a resistor or conductor squealing (the board always has power)
If it from the battery, its either the BMS or the battery itself, in this case, buy a 20kg bag with nice sand

I understand. My question was, When you turn the wheel on at the place where you charged it, it has a different sound?

Idon’t know if there is any other sound. Maybe a very soft humming.

Do you think it’s dangerous to plug in the wheel and charge it again? If there is something wrong with a battery cell, can it explode or start a fire?

Not very likely but still possible. I would keep it in a fire proof area until you know what is wrong.

as long as we dont know where these sounds are comming from it does not matter what i think.

if you put your ear firmly  to the pad where the battery is, can you confirm the source of the sound?
