Yeah, this is really apparent once we get over 12s. There is not much consistency in how MFGs are rating their ESCs.
I think I’ll split the voltage column into a “MFG recommended li-ion battery voltage” (12s) and a max ESC voltage (60v). I’ll only be able to go off of what is listed on product descriptions unless there is a resource or testing that shows a v6 can go up to 62.5v for example.
While we’re at it can we put firmware notes with each ESC? I tend to see a lot of confusion with which firmware versions to install, and in cases like the uBox there’s custom firmware that needs to be installed.
As google would tell you. 4.x is an inferior hardware design. Moving to 3 shunts solved alot of problems the 4.x hardware had. Things might have improved for the better in later FW but the three shunt design together with a fresh powerstage was the biggest contributor towards stability in FOC
This is how I understood it too, but Frank added “based on FW4.xx” so I was wondering if he was saying “The 12s FOC problem was with v4 hardware with firmware version 4 or earlier and solved with the new firmware version 5”
That or he could have meant HW4.xx referring to the hardware series
The HW and FW version goes hand in hand since alot changed between the two.
You cant run 4.x FW on a vesc6 and you cant run 5.x FW on a 4.x HW version.
Yeah, and the intentions (as far as I know) is that third party or “modified fw” would be auto-detected as well, if they were a valid branch to the project.
I dont belive accomplishing the vedder stamp of approval is terribly hard. Ppl are just lazy
I don’t believe this is true. We used to run FM v3 on vesc 4s and I’m fairly certain my v4 took the latest 5.2 firmware when I updated it with the VESC tool. There is a hardware config file in the firmware that adjusts based on the hardware it’s running on, but the overall firmware is still version 3, 4, 5 etc.
I could be wrong though, I’ll confirm tonight when I check my VESC 4
Hm, I’m unsure of how the FW evolved at this point in time, I havn’t tinkered with a vesc 4 since… I dont know, 3-4 years ago? Not even sure the vesctool was released then. was probably the old BLDC tool.
Maybe the FW revision also reflect if they’re vesctool compatible? Maybe theres a revisions number legend somewhere, where Dr.love when you need him @Deodand
Thank you everyone for the edits so far! Lots of good information being added. I’ve cleaned up some formatting and edited any current ratings that were combined to be per motor. I’m trying to keep the column width and count at a minimum so it’s easy to view on a phone and at a glance, but still add enough relevant info to help decide on an ESC
Changes by the community so far:
