    Questions From A New Member

    Hi the generating of hub has been answered already, so i want to comment on another aspect you wrote about: I would refrain from adding another battery parallel later on. too much hazzle to get it right.. Rule of thumb: always parallel your cells first then series them. I would rather up the...

    Getting Vespa engine swap legal in germany

    Hi, you definetly do not need a emv test by law for conversions of 10/2002 and before. I have done two by now. Those TÜV guys just hide behind a sub clause that they can ask for one if there is a good reason..simple stubborn petrolheads or, my guess, too lazy to learn something new. They...

    KAWASAKI ZXR-E

    Hi, I paid just shy off 200€ for the "changeover- check" (?? do not know how it would be called)" and the "classic 2 year" check all together. the latter being around 45-60?€ on its own. You then have to get new papers for your bike which is around another 45€ ....on top of my head.. why not...

    KAWASAKI ZXR-E

    hi to pass MOT (TÜV) in germany there are surprising little rules: Any bike before okt.2002 won`t need an emv test (electric magnetic noise / interference test) If bike does not exceed original top speed, original max hp (easy for electric only the long term rated power is considered), and...

    Hi thanks on the leafs: no these are not the cells i used on my xtc conversion. Those were from ali... and were definetly geared for energy rather than power eventhough they had different specs on their site... Leafs are awesome actually, i do get about 100 ah out of those 112 ah pacs. i...

    KAWASAKI ZXR-E

    edit: i have updated the wiring scheme. please note that the relay within the blue circle in last pic is not yet realised. I want to do that in order to stop the dcdc to slowly depleting the 12 v life over time. i do not mind the little it takes from the main bats, for longer storage i simply...

    KAWASAKI ZXR-E

    The whole battery can be hauled into and out of the bike without any wires "life" as the disconnect can be locked shut. Place in bike and connect +/- to controller and you are basically ready to go... if life was that easy :) Tapper bushes for the reduction stage:

    So my basic measurements told me that i could just fit the 6 nissan leaf packs, and in order to avoid chain whip a 2 stage reduction was on order, to give me about 4.2:1 reduction. CAD:

    Hi all, i have been lurking mostly here on ES since a couple of years, awesome knowledge gathered here. I did two build logs over on el-moto but unfortunately the forum is down for some reason or other. Anyway game called give and take so i guess its time to give back some to you all. Ok...

    how to program a sevcon gen4

    COULD IT BE THAT SIMPLE? Well it is said that the problem usually sits in front of the device... After getting some replies from the vendor, stating for example that Motenergys inductance of 0,10mH translates to Ls 90 in the sevcon i was left again puzzled of why ii do not see full power. A...

    how to program a sevcon gen4

    Hi, i do not know why either. I would though change to correct value and make sure that all other related values like low and high voltage cut offs be correct values too. Just because i want to have things right... flo

    Newbee with some basic electrical questions

    Hi amberfwolf did give a very good explanation but i want to get back to the breaker and fuse for another reason: So first off i distinguish the breaker and fuse: fuse for an emergency only disconnect (technical problem), while breaker is used regulary on my bikes( i can lock mine shut with a...

    Chinese electric moped suggestion, configure controller or other fun?

    Hi, first off why not simply getting a "bigger" model? might turn out cheaper and less hazzle in the end... Anyway as you are posting from sweden you do realise that you are asking for advice on "illegal" changes... (internet is not law free area)? Anyway: If you simply want more acceleration...

    how to program a sevcon gen4

    Hi, i will check if inductance moves around... I do not know where the values originate from... as said i bought this "fully" programmed... i did not align the position sensor... so i would need to create a new torque map with it too? :roll: flo

    how to program a sevcon gen4

    Hi darsey, thanks for the explanation. Well what i am missing is what makes electric riding so special: basically 100% torque from 0 rpm - simple as that. (and the reason to change from kelly). It starts pulling at about 12kph and does so up to approx 100kph, than tappers off... Anyway i...

    Newbee with some basic electrical questions

    Hi, i use a little 12v life bat to "straighten" the voltage, especially as some controllers won`t like the rippled voltage a dcdc produces. A circuit breaker is there to safe your equipment, if your controller can handle 200A that would be the right number then. the breaker should rated at...

    how to program a sevcon gen4

    Hi, 350A rms was set by the vendor, in his initial reply to my specified wish list he answered 350 A as the controller limit gen 4 size 4 !! As for the abreviation RMS ... i believe that accounts for long term (opposed to peak) rght? than it would make sense, otherwise the max should be 420...
