pushbutton? hmm
sometimes you have only seconds to engage brake.
pressing pushbutton would have to be very strange way to engage regen braking
For me, the pushbutton is actually on the lever and will be basically be pushed anyway when applying the brake. :D

Re: Magnetic brake cutoff sensors on road disc brakes?

When I have time to revisit the road bike build, I'll buy some of these instead:

Would seem like it would be more likely to work.

Re: Magnetic brake cutoff sensors on road disc brakes?

Here's where I glued the sensor on mine: IMG_20210909_200833.jpg Magnet is inside lever on the hinging piece which moves up and down when pressing the lever in and I could never get a good picture of the placement. Anyway, the setup was very sensitive to placeme and only worked well for a while. Onc...

Re: kWeld -

So what input voltage range do you use with the 4S? How low would you go with 3S? 4S was at 9V when I tested it. Fully charged would be about 10,4V. 4S voltage range is between 10,4V-8V 3S would work between 7,8-6V. I tried 2S first, it gave calibration current of slightly over 1000A, so would also...

Re: kWeld - "Next level" DIY battery spot welder

Thanks for designing a great welder! Such an improvement to my earlier car battery-solenoid-timer relay DIY welder. LTO seems to work great as a power source as well. 4S Yinlong 40Ah cells produce 1800 amps at calibration on the stock cabling lengths. 16301798343011564373918584375593.jpg Cells are n...

Re: Using EV Chargers

The CHAdeMO would be the better. The charger is in the station not the EV. Like for a e-bike/trike you would not need to carry a charger but the connection would be huge and the electronics to control it. This was exactly the same as my thinking. To carry a 8 kW+ charger with is a lot more weight t...

Re: Using EV Chargers

CHAdeMO is on the losing side of the standards war, even in the US. Sadly seems to be, but hopefully it will still be included in new charger installations for some time! Hope a more standardized plug and protocol are implemented in the meantime... And I don't know of any networks that allow bikes ...

Re: Using EV Chargers

This is known but going to say it! DC fast charging relies on the station to provide the DC current and this is expensive. This is why we don't have any at home. This other charging standards provide AC current to the DC chargers in the EV. I agree that there is no point in charging at high speeds ...

Re: Using EV Chargers

Hope charger manufacturers realize the potential market for LEV's and include that little bit of extra conversion to go down to 40ish volts in the future!

Loving that most CHAdeMO chargers do go down to 50V though! Sadly it seems that they're getting rid of it in newer models to save money though...

Have you considered charging at DC fast charging stations instead? I just finished a similar battery for my bike, in a trailer. 26S1P 40Ah LTO with CHAdeMO charging. Sadly, I didn't get to the 240A chargerate I was hoping for (I had looked at the newest CHAdeMO spec, which goes up to 400A), but 125A...

There's a plastic spacer in the top picture, since I took too much material off initially. I can use all the cassettes cogs, although the largest one sometimes skips a bit since the der...

Thumbs up for the 1500w leaf motor cassette version. Been running mine with 11-speed road cassette (sram apex) for 3200+km now no problem. I just had to machine a 1mm groove onto the inside of the largest cog on the cassette to get it to fit on the hub with the lockring catching.
