They need an ebike lobby in NYC/New York State! There is an extremely active bike group here in DC that continuously lobbies the city council to amend and change their laws. They are called Washington Area Bicyclist Association (WABA). The group has been very successful over the last couple...

This past December I finally finished converting my Project 346 inverted Basman frame into an Ebike. This project has taken me 3 years. I really fell head over heals for this frame back in 2012. Originally wanting to buy one of Marty's complete electric Basmans from Voltage Cycles, I ended up...

Hey Fechter, Just wanted to say (sorry, I know this was a month ago): The switch I got to work actually does completely cut off the voltage from my battery like your design says it should. I was a tired doofus that night and measured from the wrong side of the negative bus bars. It works great...

On Thursday I got around to replacing the MOSFETS and testing the old ones. I also added the additional 1M resistor between the Gate and Source and everything is working great now!! No more sparks when hooking up the Anderson Powerpoles and the reading from Gate to Negative switch line is at...

I really liked your boards from oshpark! Two things kept me from ordering it originally: 1) being that I wasn't sure at first if you were using a switch to cut off the battery completely (after re-reading some of the earlier pages 15-19 again I now realize I might have been missing some info)...

With your help Fechter, I believe I now have it narrowed down. So with the switch and power off, it would read .8 ohms in the correct direction and then zero in the other. That made me wonder some. So then I disconnected the gates of the MOSFETs from the wire going to them and applied the...

Yea, there is definitely something wrong. So I tested it as suggested. When the switch is off the voltage reads at zero...when the switch is on the voltage only reads at 22 millivolts and stays there. It doesn't rise at all. So I am thinking my MOSFETs are probably blown if they are not rising...

Hey, sorry about the bad photos (was a little tired last night). Attached are two new pics of top and bottom of the circuit. Also attached are overlay versions of the circuit diagram (from page 6 - the "switched" version) to make it easier to see what I did. The capacitors are definitely...

So, I have built the circuit (switched version) by Fetcher from page 6. I used the layout he provided as I figured it would be easier to follow that way. Spent the last three nights after work trying to figure out why it is not working. I definitely feel like this is probably some horrible...

Hey Everybody, I've been following this build for a little while. I am also interested in building one of these circuits for my large-sparking problem when hooking up my battery to controller. I would like to build the version Fetcher posted on page 6 that includes a switch. I also have 48volt...
