Levo Gen 3 Hot charger

[Timwillows]

Im used to the charger block getting warm while charging, but recently it’s been positively hot (too hot to hold comfortably) slightly smelly and with a slight buzzing noise. How unusual is this and can a dealer do any diagnostic check on the charger?

Heat, smell and buzzing are not good signs, I would be afraid that it will catch fire one day soon.. go to see your dealer..

buzzing is probably a capacitor or something on it's way out, I'd try and get the charger replaced.
what charger do you have though? Itheres a fast charger maybe that one gets hot?

I think the one I have takes about 4 hours for a full 750wh charge and the charger barely gets warm to touch anytime I've checked it.

I have the standard charger that came with my bike and use it to charge my 700w battery.
It gets HOT, hotter than any charger I have used in the past.
From what I read that is normal, the buzzing sound probably not, have your dealer check it out.

Electrical devices in the 160° F to 180° F range are perfectly acceptable. Depending on where you are, you're plugged in to 60 Hz or 50 Hz power. That's well within the range of human hearing. Electrical devices frequently make audible noise.

My only advice is the same advice that I'd give to anyone charging a bike: Do it in a well ventilated location to provide adequate cooling, and keep flammable items away from the immediate area. If he charger is functioning properly, the Bike Store Boys aren't going to be able to tell you anything helpful.

My charger is getting hot too. When it charges the last 20% (80% to 100%) my charger also makes high frequency noises. I went to my local bike shop and the shop replaced the charger. The new one makes the same noises and getting hot too. So i think it´s normal (230V - 50Hz).

It’s not normal and they shall substitute. Mine did the same, send it to local shop and they sent me one. Did the same. Later send it again to another local shop and they substituted and it’s fine. Doesn’t get hot or noisy anymore.
Mine also got hot from 80% onwards.

I think having a desk fan or any fan blowing air on the charger when charging , they do get hot ,which can do some internal self inflicted damage.

Frying pan on top. You can cook a couple of eggs while the battery charges.
When the buzzing sound starts your eggs are done. Useful feature.

Mine will get to 140 degrees F maximum when the battery is healthy and I don’t run a fan. On 2 occasions when they were getting hotter both bikes had bad batteries and were replaced under warranty. I also run a small fan when charging our bikes and they don’t get over 100. Have never had a charger replaced but have had 2 batteries on different bikes replaced and the charger temperature was a indicator.

Ok....will talk to my local bike shop. ;-)

Just checked mine with a temp gauge and it shows 140*f in the middle of the charger and 120*f around the sides.

Some facts!

I think I will check mine next time I charge it. The only temperature gauge I have is the sort of thermometer that you stick in your mouth. I wonder if I could use some Blu-Tac?

I just picked up a cheap from Amazon.
Kizen Laser Pro LP300.
seems to work pretty well.
I think it cost like $30 if I remember correctly.
