THANKS

or could it be that the voltage being so close to 63 that it blew a compromised cap? Was definitely a hole in that cap. But I'm only knowledgeable about electronics to be dangerous to myself :) I really don't know how it would work or how it could fail

thanks. I agree, however, It was double heat shrink'd, hard to see how it could rub together? and the way it was installed on the bike, even harder to imagine. no tension on it either. Could be just the high voltage? 58.8volts charged for the 52volt batteries I use. and they were very close...

Interesting: I found these two shorted wires. Main heavy wires from battery to controller. They were well soldered and thick high temperture heat shrink, but they were in the same spot. Question: did the cap blowing cause this short? or did the Short cause the cap to blow? I'm thinking it was a...

Got the new ebike controller, sine wave type, with C600E LCD. opened it up and these are the capacitors: what do you think? any good or not?

Thanks! I'm checking it out now from your link. :)

I'm replacing the LCD3 v7 with C600E-USB V7.0A and want to know: can I use with my twist throttle? and I do not have pedal assist, does it require it? I have the geared rear hub 1000 watt setup from gocarlite.com Controller failed, ordered this C600E-USB V7.0A and a sine wave controller from...

THANK YOU indianajo. You nailed it! :) I will disassemble the sine wave controller and check what's in it. I've checked digikey and newark, haven't found any ecaps that I want in stock yet. I may get the controller today. We will see.

found a pinhole in 470uF capacitor, checking at pic that shows both capacitors, lower center of pic, a white circle around a black spot that when examined with a magnifying glass and checked with a needle, shows a pin hole and flash damage to the cap and to the jumper bar on it's right. There...

thanks ! I'll have more time to tackle it tomorrow, and call the guy I got all this from. gocarlite.com, Doug is the owner. If you check it out, the 52 volt kit is what I got from him 8/14/2014 for $1180. and 4/5/2018 I bought and he sent me new controller along with the LCD3 version3. For the...

didn't take out the side screws that are pretty tight. but so far can't see any sign of cause of smoke, nothing looks cooked either, no smell. looks like case is used as heat sink on the left side, that's where the screws are? Has four 63v 470uF caps, name looks like LSHG. ? are those cheap...

VERY useful info, thanks. any idea where I can get a good controller that will work with my hub motor? That is good quality? meanwhile I'll take this one apart and check it out. Thanks

Thank you very much for the feedback. New info though: today I rode it to Sebastopol and then stopped off at a friends house. 37:20 min, 17.36 mph average made all the lights; 10.8 miles, then went home, taking 15 min. 2.22 miles total, but it died again, heard a snap, instantly dead, thought...

Nice to find this forum on ebikes, thanks. I've posted a few times. Mentioning I've been riding, modifying and installing kits for my bikes since Sept 2000. I have a leaking heart valve, not life threatening say the doctors, but it is like a rev limiter on a car. Past a certain point the valves...

(I've been using and modifying electric bikes since 9/8/2000.) Some basic truths about watts and power: The amp capacity is like the size of a gas tank; the discharge rate is how fast you use that capacity. The controller limits the amps output. Watts are volts times amps. The motor rated at...
