No fuse that I can find. I did send them an email but they are in China so it will be late tonight before they reply. They are a great company and very respected so I hope they will take care of this. I just made a "click" and went off. Update As expected being the stand up people they are...

I went to charge my battery for a bike trip tomorrow and I heard a slight noise and now it doesn't turn on. This is one that I bought from EM3ev. I have only used it a couple of times.

Relax and take in a little fresh air. Some of us just want a simpler solution and you can keep your negative comparisons to yourself.

Kepler, I have been following this thread for a while and also have an observation. If you want this FD to really take off I think it needs to be in kit form or at least greatly simplified. I am past the point of wanting to program things or do a McGyver to get the bike running. At least...

Kepler, so how fast would a FD go? Say compared to a BBSHD all other things being equal.

Thanks. I think this may be perfect for my wife. She only rides occasionally and always on paved flat surfaces. Some torque would be nice for getting across busy streets when there is a break in the vehicle traffic.

I am considering converting my wife's bike to a friction drive but am pretty much clueless about the parts that are needed and where to get them. Since you have experimented with various motors, throttles, controllers,batteries, ect it would be helpful if you could provide a list of components...

I won't pretend to understand the technical details but thanks for the bottom line answer. So, if I use the meter to measure battery performance white I am riding the data will be lost when I hit the lvc or 39v in my case. Correct?

When I said "independent" I meant the meter doesn't care if is wired to a bms or not so therefore it should work at 39v DC. It may be defective, it was only $10 shipped from China. It works fine at higher voltages just not at 39vdc. Anyway, the battery works and I have my trusty multi-meter...

The watt meter must shut down at something under 38v which to me seems strange. I understand that the bms has a lvc as does the controller, but the batt meter is independent of those. The battery still showed 38v which should have been enough to power the meter.

If the battery pack uses a BMS I would venture to guess that BMS was in fault/protect mode thus unable to deliver a few mA's GT Power meter needs? It is one of Paul's batteries so it has a BMS. I actually tried it twice. I put a small charge into the battery and rode it down to the LV...

That is correct. The battery still had about 38v in reserve but that was not enough to activate the watt meter. Interestingly, when I put it in line with the charger, which immediatey, jumped the voltage reading to 44v from 38v it worked. There is a small variation from my multi-meter vs the...

I have it hooked up correctly. It works from the charger to battery, when charging.

I purchased a cheap watt meter (GT Power) and put connectors on it so I could monitor my new Em3ev battery and the charger. I just completed my first total run down of the battery ( 50v 15Ah). Fully charged it was 58.6 and it cut out at 37.3 according to my multi-meter. I connected my watt...

She rides slow, the trail have a max speed of 15mph and I doubt if she would even hit that. There is always that concern of front hub motor snapping the dropouts but I would definitely put on reinforcement. This is an aluminum frame so even more of an issue. I was thinking small motor, low...
