Electric Motorcycle Conversion / Re: Special bike (old trial) converted but weak
« Last post by Bikemad on October 20, 2024, 09:50:05 AM »Lowering the maximum drawn current did the trick but I had to lower it to 100 (default setting was 250!).
I think you may have lowered the wrong setting as the 48V VEC300 controller is only rated for 120 Amps of battery current.
However, the Phase current is typically a lot higher than the battery current, as Phase current is delivered in a series of high current pulses supplied directly from the controller's capacitors (the VEC300 controller is rated for 300 Amps of Phase current).
The *.foc file I have saved from a VEC300 controller shows both the Rated and Phase current set at 280A with a battery current of 110A.
Try resetting the Maximum phase current (A) and the Rated phase current (A) to 250 and leave the Battery drawn current limit (A) at 100 and see what difference it makes.
If it starts cutting out again, try lowering the Battery drawn current limit (A) until it stops.
However, if it does improve the torque without cutting out, it might be worth increasing the Phase current to see if you can improve the torque at low throttle.

Now the bike won't cut off but it's pretty weak if compared to how it was. Yeah, I can twist the throttle completely but I can feel it lacks the torque it had before at half throttle from a dead stop.

Did you try reducing the Battery drawn current (A) setting to see if it made any difference?
You might not be able to pull the higher current required from the battery for increased torque if your battery/BMS is unable to supply it.

You should be able to gradually reduce the Battery drawn current (A) setting until the battery no longer "turns off" under full throttle.
Tried to up the boost, the maximum drawn current etc. but the bike now will go into protection as long as the throttle is twisted fast.

« Last post by Triad on October 16, 2024, 02:24:49 PM »Ok, another update: I finally put the bike back together after altering the primary belt and pulley. It's definitely way more powerful from a dead stop, but even after disabling the protection voltage it will still "freeze" if I give full throttle. Why and how can I fix this?

to the forum.
A quick Google search showed that Klabauter Shop in Germany currently have 2 PI-400/HPC programming cables in stock:
Make sure you purchase the PI-400/HPC not the PI-400/VEC which uses different connectors and programming software for the Vector controllers:
I have also attached a RAR file containing the HPC programming software and user instructions for the HPC controllers in case the version you already have is incorrect.

General Discussions / Re: Expected resistance range for pot throttle on VEC500
« Last post by Bikemad on October 09, 2024, 10:46:13 AM »Hi John,
Unfortunately I am not aware of any way to stop the beeping when the regenerative braking is active apart from physically removing the beeper from inside the controller.
If you wired another switch in series with the throttle switch it would allow the regen to be turned off when not required, which would be very useful if you wanted to use cruise control, simply coast without braking, or even use hand signals while riding.
If the throttle had a much stronger spring in the microswitch (or possibly a rubber "O" ring around the microswitch operating plunger) it would only activate regen when you intentionally twisted the throttle backwards to the fully closed (regen) position.

General Discussions / Re: Expected resistance range for pot throttle on VEC500
« Last post by Jbunn on October 06, 2024, 07:52:07 PM »Hello Mike! Thanks for the response. I've given up on the idea of a pot based throttle and am going with a hall based throttle. Most of the reason is on the hall from Domino, it has a microswitch which is closed when the throttle is in the off position. This switch is to be wired to the low brake connector on the controller. My understanding is that's how you enable regen on the VEC500 controller. I ran some brief tests, and closing that circuit stops power to the motor, and the wheel stops rather quickly. (it's on a motorcycle on a lift with the rear wheel off the ground. The only issue remaining is the controller beeps when the circuit is closed. Is there a way to turn off beeping on regen? Please don't tell me I'm going to sound like a delivery truck in reverse every time I ease off the throttle.
Thanks!!
Thanks!!

« Last post by Triad on October 06, 2024, 12:28:16 PM »I can turn the bike off with a switch on the fake tank... so if there's no chance of harming battery or motor, I'd go for it.
It got worse after I altered some of the values, though. So I guess I'll have to put it back to default settings and then disable the throttle voltage protection.
I activated the "turbo mode" or something like that, as it should help the motor from take-off... I'm not very interested in top speed but I'd like more torque/power down low and from a dead stop.
