Are the DPS betteries water cooled? Can they work without a cooling system?<br />I really like your motorcycle and this blog, congratulations.Pablohttp://www.dechavesgarage.comnoreply@blogger.comtag:blogger.com,1999:blog-6799381509624326749.post-90920084843411719772010-02-01T22:49:13.114+01:002010-02-01T22:49:13.114+01:00I tried commenting with my name, but your comment form crashed several times.... so I gave up.

I&#39;ll answer some of them on succesive steps. At some of them I can&#39;t give you the answer:<br /><br />The bike weigth about 170Kg and can handle the 160Km/h for about 25-30 minutes. We used two gears beacause we think should be enough for the actual performance of the bike, going gearless won&#39;t allow us to use a currante swingarm because of rear sprocket size.<br /><br />We use 4 DPS UBM5036 batteries for a total of 7,2KWh<br /><br />Now I have to work ...Carles Carrerahttp://www.blogger.com/profile/01115109506284595206noreply@blogger.comtag:blogger.com,1999:blog-6799381509624326749.post-85002865002635738612010-01-27T00:17:41.787+01:002010-01-27T00:17:41.787+01:00how heavy is the bike?<br />what is the absolute top speed?<br />What are the gear ratios for the transmission? Why 2 and not 3 speeds?<br />What kind of electric clutch? Why electric?<br />How far at 100mph (160mph) can it go?<br />What kind of batteries are being used?<br />What kind of motors/model numbers?<br />How has the bike been integrated?<br />what kind of display is being used?<br />Do you use regenerative braking on the rear wheel? if so, how is it controlled?<br />Does the controller or the BMS control LVC?<br />Do you do LVC based on the cellular-level?<br />Does the BMS sense current, or do you depend on the controller for that?<br />what kind of dc-dc converter is used?<br />what kind of charger is used?<br />what size chain? 530? 428? other?<br />Why the benelli frame and not a Derbi frame?<br />I see it says there are 2 motors, but are there 2 controllers? If 1 controller, how did you get 1 controller working with 2 motors?<br />does the BMS talk to the charger?<br />does the charger talk to the controller?<br />who controls the contactor? the BMS or the Controller?<br />Why chose an existing frame and sacrifice the ability to design around batteries and motor?Travis Gintznoreply@blogger.comtag:blogger.com,1999:blog-6799381509624326749.post-82134456682400487472010-01-26T18:43:04.790+01:002010-01-26T18:43:04.790+01:00how far can you go at 160km/h? 21kw peak seems awefully low for 2 motors.

If it&#39;s DPS cells ,do you water cooled it too ?Four cells pack ?two under the bike and one on each side (4x24v 50Ah DPS)?Lot of question i know .I think you have a very good concept.Please market the complet bike or the drive train ASAP.<br />Best regards.
