Since the first day I got the charger its ran hot. To the point where you can smell heated plastic. You can barely hold it in your hand flat palmed. If you grab it and hold it you will probably get burned. Its only hot during charging not during floating.The output is 15.3v 5A charger. Anyone else have any similar stories.
 
Is the fan running? I had the exact same symptoms on a 48v 10a charger from ecitypower/bmsbattery. I opened it up, and saw that a plastic part on the fan was broken so the blades wouldn't turn. I fixed the piece with some superglue, then the fan worked great, haven't had a heat problem since.
 
My cheap Lithium 2A/36V charger brick also gets very hot and stunk to high heaven when new. It doesn't smell much anymore and it has worked for over 90 charge cycles so far. The 3A/48V charger I got with my latest LiFePO4 battery purchase has a little fan in it and it runs cool though it does totally disrupt my over-the-air television reception when close by (I thought my TV was broken at first!).

Even my ping 2A charger has a fan. Are you sure it just not spinning?


Edit: Nevermind. I just noticed 12V. I'm talking about a 48V.
 
Drill a bunch of 1/4 holes in the housing, after removing it from the boad of course. I do this to all my fanless chargers and they run much cooler, and stop stinking. The vents in many chargers are a joke, and may have the slits clogged with exess plastic that were supposed to be open.
 
I agree, drill some holes near the bottom. Enshroud the holes and attach improvised ducting and a fan from a scavenged old computer. The design engineer may have said it works just fine as it is (no fan makes it $2 cheaper) but fan-cooling cannot hurt it, and can only make it better.
 
the charger may just be hot because it is inefficient at such a low voltage. if the heat is extreme, just take the cover off so air can circulate around it. keep you fingers off the traces on the input side though, up to 354V noise on the diodes.
 
Holes top and bottom is my method. Convection keeps the air flowing through allmost as good as a fan.
 
Hi '

Sometime ping charger are faulty i have 4 charger form him here and only one as fail so far

they all have fan inside but they get warm all the time

2 week ago I bougth one charger from vpower on ebay and its a 5 amp 36 volt charger and stay cool all the time and is good quality also

the charger is heavy and I believe its a true 5 amp charger because I made the test and took me 1 hour to gained 5 amp
on my battery

also usa and canada there no shipping fee so you paid 47 us thats it , Ping ask 50$ + 40$ shipping

I respect Ping but I am very happy with my new charger

which charger of ping's did you have fail?

the small ones have a fan too, but the entire inside is one big heatsink up against the inside of the case which is why the case gets hot, it should have airholes too on the opposite end from the fan. but maybe you have something different since he only makes the type A down to24V.
