Re: Help me write the ES wiki

Alright, so how far are we yet? Is there already some link to the wiki? Can I help with writing articles of how to build / weld a battery even when it´s already finished? I will have plenty of time after June 2018 to spend on writing professional articles about that stuff I have learned in the past...

Re: Suzuki RF400E, now with Enertrac MHM602

I got a semi-cheap H4 LED headlight, fitting was a breeze - no tools required ;). US$ 7 on Banggood The light pattern is more than OK, there's a clear cutoff, no glare, just an area that's not lighted directly in front of the bike. I'm not sure if that's good or bad, will report if I ever ride outsi...

Re: Electric Motorcycle Parts Help!

Check out some other builds on EV album: http://evalbum.com/type/MTCY.
And please, no lead. AESC / Nissan LEAF modules are plentiful, other OEM's might fit even better. 18650 if you have too much time on your hands ;).

Re: Suzuki RF400E, now with Enertrac MHM602

I spent some time replacing the insert that's plugging the hole the filler cap left (with PP/"corruboard") and spent some time sanding/de-rusting the inner part of the tank:

[EU] Kelly/ZJW 200A/12V contactor & GEFRAN GS40A SSR

Both items are used, I got them with a set of which I used the controller, motor and cabling The contactor weighs about 700g, so I'd prefer shipping within the EU (€9.00, yes, that includes UK :)), but worldwide is only €12.25. Details can be found on the Kelly site . I'd like €30. The SSR weighs 20...

Yep, 2 actually :D. I blew the DC/DC on the one board I had working :(. That's the long-term plan (and why I passed on the bigger Kelly above). At the moment I am getting the secondary functions on the bike sorted as it's my daily driver - weather protection, heated grips & other conveniences, put t...

Re: 1970 Vespa 50s electrification project

Glad that what I found works out for you! One note on the connectors, I use the waterproof ones liberally (on the car as well). I think they are Tyco knockoffs. 15 sets are less than $7. Flat pliers work, but long term you'd want a crimp tool, I have something similar to these . Edit: in 1 and 2 pin...

Kellys work best fully isolated, so I'm using a relay to trigger the 5V from the 12V brake input.

[..] I wish this all made a little more sense than it does at the moment, you're saying you want to control the rear brake independently of the front.

You can always send it back:).

Re: 1970 Vespa 50s electrification project

Shiny equipment there mate. :D My thinking is that I want to be able to control the rear brake independently from the front, thus the disconnect. With the weight in the hub (potential) rear braking force will be stronger than before, so I want strong regen to help the smaller rear caliper. See my th...
