The connector design is changed to allow for easy connect/disconnect. Much progress is made with the phone application development, including online logging directly from the phone app.
Connectivity package (GPS+GSM/LTE) with 3 years of service in 70 countries is now available as an option on new controllers.
Here's Jacopo, senior software engineer from Italy. We're working on a new electric dirt bike (30s, high amp) and have been following this thread for a long time. Just PM you ;)
I am Burak from Turkey. I am Electrical and Electronics engineer. We develop electric motorcycle and would like to work with high voltage controller. I would like to give a try this such an amazing product. I just send PM.
Looking for testers that are properly set up to test the controller design up 30kw. Ideally, at voltages up to 134v and currents up to 400A.
I can only load it up to 10kw with my current setup and I'd like to validate higher power levels.
You'd need have the right battery, motor and the way to load it, as well as experience setting up hardware running vesc firmware.
PM me if you have the proper setup, knowledge, and motivation to run the tests and provide me feedback.
Due to component supply constraints, I can only produce a limited number of units, therefore, I am looking for experienced testers only to validate the design.
Considering offering 100v and 200v version of the controller (in addition to the 150v). The 100v version should be capable of 500A phase, and the 200V obviously higher voltage and likely up to 300A.
My simple smoke test for any controller (without actually smoking it) is to check the claimed specs against the specs of the parts used inside and how that controller is made. The test is oversimplified but it provides a basic idea of how far the claimed specs are from the reality.
Let's say a controller is using 24x IRFP4321 or four per phase which is what's likely would be used on a controller with To-247 packaged 150v rated mosfets.
The datasheet (that tends to be always over optimistic) tells us that the continued drain per mosfet at 25C is 78A. So, 78 x 4 = 312A. That means provided the mosfets temperature can be maintained at 25C (impossible with passive cooling and in standard ambient temperature), the mosfets would be good for up 312A load of DC/non-switched load under perfect conditions. Switching adds another layer of losses warranting additional current derating bringing it to 250A at best. It doesn't mean you can't push it for a couple of seconds a few times and then wait until the temperature goes down but this is far from continuous and well above the safe specs for the mosfets (aka compromised reliability).
Great! PM Sent, hope to get one soon!

I'm interested. PM on the way.

Jestem zainteresowany wykorzystaniem tego sterownika do samochodu solarnego. Daj mi znać, jeśli coś jest dostępne!
Are there any update's ? Looking for a high power vesc.

PM sent, very excited by the prospect of testing this hardware. Provided a good chunk of context. I'm a mechanical engineer located in Atlanta, GA.
I have a couple of controllers in stock available for immediate shipping. PM for details.

Hi, i wrote PM
Seems like no trouble running an axial flux motor. Here is some test:

I'd bite depending on the price. I'd like to hear how it compares to the Tronic 750 which is not cheap at $900 but has these specs:
