Anyone have there Emag charger fail?
I thought I had bad batteries but when I looked at the charger it wasn't putting any current in to the battery pack. I am an EE at a power supply company, so fixing it was a breeze, turns out that the current sense resistor used is a 1ohm, 1/4w and they are running it at 1/4w, over time the 1ohm resistor turned to 65Kohm. So I replaced it with a 1ohm 1/2W, and everything is okay.
Just curious if anyone else charger has failed them.
