Controller delivers too less current?

no, I'm definitely not measuring AC. This is the Ammeter I have: http://www.tequipment.net/pdf/LEM/2050_man.pdf On site 5 there is a sentence: "all measurements DC and 10Hz to 1kHz" Is this the frequency it can measure? I don't get it.... Therefore I can't find any information about measurable frequ...

Controller delivers too less current?

mmh, I used a cut off Voltage of 48V as controller setting, because there is is no undervoltage monitoring. I always thought it sets the possible current to zero. But here it sounds like, it would just decrease it. But if it would decrease it to the lowest possible current, that voltage is still ove...

Controller delivers too less current?

Hey, It seems like I have a problem with my controller. Its a Kelly KDH12601e (600A max.). System: Battery: Headway 40160SE 16 seriel, 3 parallel Motor:   Agni 95R Controller: Kelly KDH12601E In the software I can adjust percentage of maximum battery and motor current. I chosen always the same. So, ...

Safe overall-voltage for no undervoltage

Hey, the testing worked pretty well. I measured the Voltage of each seriel pack from time to time, and they were all almost the same.

But I got much too less torque. Think its a controller problem. Started a new thread.
Thanks for helping me out here :)

Voltron, the Electric RG!

Hey, contacted today again Fany from kellycontrollers. After all, it seems getting the rpm by the KDH12601E (brushed DC Controller) isn't possible. Fany confounded the KDH12601 with a brushless controller and sent me wrong informations.... Great, to find out this, after we already bought it because ...

Safe overall-voltage for no undervoltage

No. It's a crazy idea. I'd be interested to see where it came from. Its from a german forum about electric bicycles. Someone asked if/how he can connect batteries with different capacities parallel. Well, I skiped the part with the different capacities. So it was my fault.... Will a triple be arran...

Safe overall-voltage for no undervoltage

mmh, ok doesn't sound good.... edit: Did you mean this?: http://stores.headway-headquarters.com/-strse-92/48v-50a-fdsh-100a-bms%2C-16/Detail.bok?category=BMS%2FPCM%2FPCB The problem is, that I have a discharge of 150A/max.240A and don't find something that can handle this. I also have some (maybe em...

Safe overall-voltage for no undervoltage

hi, actually I'm building a E-bike with s16p3 Headway 40160SE Cells. The problem is, that I still have nothing against undervoltage at each cell, but I want/have to do some tests. So I thought I set a undervoltage at my controller which should measure the overall voltage. Do you maybe have some thou...

Voltron, the Electric RG!

Hey, thanks for the fast reply. Some days ago, I asked the Kelly support if it is possible to get an rpm signal by CAN-Bus output. What they answered was: "You will find the command list for CAN bus in the bottom of the manual. Yes,you can read the RPM direclty.You only need to configure the poles o...

Voltron, the Electric RG!

Hey there, looks pretty nice, your bike. Aktually I registered here, because I have problems in understanding the electronics and hoped somebody could explain a little. I'm an engeneering student and have a project, building an electric bike. Why you use such a (for me) complex build, like you poste...
