Quick (and probably stupid) question about the anderson tap

I just went to buy one of these: http://www.ebikes.ca/andersontap.html and then I noticed it has a 2.5a polyfuse. Does this mean I wouldn't be able to power lights which use more than 2.5a? If so that seems a bit low doesn't it? The light I was hoping to power uses 12v at 3.6a on maximum power mode....

Re: I opened my hub motor and found this....

I only removed a couple of the sprags, and have now put them all back in place, which was pretty fiddly, but its now missing the plastic retainer in places. The motor seems to work, at least for the time being, hooray! :D The grinding noise I described in the first post was just one of the cylindric...

Re: I opened my hub motor and found this....

As it had shattered I decided it definitely had to be removed before any more broke off and got caught in the gears. But it turns out its not actually a magnet. I dont really know what it is but it looks important. Does anyone know what it is and if I can get a new one? I've contacted BMC who have t...

I opened my hub motor and found this....

Hi guys. I've just taken my motor apart to tap some new threads for the cover plate as all the old ones had been stripped. When I went to put it back together, there was a grinding sound in one direction so I took the motor out of the casing and found this: https://dl.dropboxusercontent.com/u/367705...

Re: Help needed troubleshooting a water damaged ebike.

Hello again everyone. I've received my new BMC controller, but there seems to be something wrong. Its identical to my previous one- 38-60VDC, 50A, but for some reason my bike wont go any faster than about 17mph, and there's a delay in acceleration when I increase throttle. It used to do about 33mph ...

Re: Help needed troubleshooting a water damaged ebike.

You don't need to use a BMC controller. Anything that runs at the necessary voltage and amperage for sensored BLDC motors will work. Since you have a geared hub and a BMC controller, I'll make the leap and guess you have a BMC motor as well. BMC motors have been notoriously difficult to drive with ...

Re: Help needed troubleshooting a water damaged ebike.

Have you opened it up yet? Will likely need MOSFET’s but it would be good to dry/clean it out ASAP in the event you want to repair it at a later time. Repair is a viable option. Perhaps buy replacement and then work/learn repairing this one. Maybe wind up with a spare? Yeah, I'm thinking thats what...

You don't need to use a BMC controller. Anything that runs at the necessary voltage and amperage for sensored BLDC motors will work. Just make sure it has all the features you currently use/need. Also, I hope you were limiting it with your CA... 3000W+ is way too much to be feeding a geared hub mot...

Re: Help needed troubleshooting a water damaged ebike.

Cheers for your help guys. I've tested the controller with a multimeter and yeah, it looks like the mosfets have blown. I guess I'm going to have to get a new one.
It's a BMC 50a controller. Does anyone here sell them in the UK?

Hi guys. Storm Frank was too much for my bike and it died in the middle of a torrential storm. I've taken the cover plate off my hub motor and left it in a warm dry place to dry out for a few days but its still not working.

Thats a pretty good idea! I didn't think if that. I'll do that, nice one! :)

Theres water inside the motor and I've been trying to open it up to let it dry out, but one bolt is completely stuck in there. I'm going to have to drill it out. Anyway, I'l...

The problem with phones they shut down in the heat. So it needs to be its own identity. Yes sinking with the phone maybe ok but not as the screen.

Hmmm... not too descriptive of your specific issues or desires.

Re: Need help choosing a DC converter for this light

You won't blow up a light by having a converter with the capability of handling more current. It won't try to stuff excess current into the light if that is what you are concerned about. The current rating on any power supply is its capacity to provide current, and the actual current drawn will dep...
