Looking for feedback on the battery I built

@RHill051 Let me clarify By default, FOCBOX comes with 2.18 FW which works with BLDC Tool only. You flashed it to FW 3.1 to make it work with VESC tool Ackmaniac Version You used this link: https://github.com/Ackmaniac/vesc_tool/tree/master/res/firmwares/410_o_411_o_412

So all I am saying is You can program your FOCBOX by staying at the stock firmware and using BLDC tool Or you can flash that Achmaniac firmware again on it to make it work with VESC tool The choice is yours.

For that disconnection, Let me know the length of your MicroUSB wire

So I decided to try to input some of the settings using BLDC just to see if I get some different results and it looks like when I click on “Start Detection” the motor actually spins up however it does not print any results to the adjacent window. Any advice on how to get the detect to work? btw HUGE thanks for helping out!! I honestly thought I was never going to see progress lol

Cool! So what was the problem exactly and how to fix it? The FOCBOX is now in working order?

Ok, So first I want to give a huge thanks to @CarlCollins!! The man is awesome!! He took the time to screen share with me and identify what the issues were. I know that a huge part of my problems were coming from the fact that I did not have the correct drivers on my computer to communicate with the FOCBOC and that was causing it to disconnect after a few minutes. I also speculate that it was part of the reason I was unable to write anything to the focbox over USB. Second we tried using a shorter cable. (or maybe just a different cable in general because the one that ended up working was probably 4 foot instead of 5 foot in length). Next I think following these steps also helped get things going in the right direction again. Without haveing tested just the USB scenario I don’t know if I would have had to do this or not but these are the steps followed and it worked for Carl and I.

I was having some issues with the motor detect process and Carl did something to get that to work but I totally missed it since he was working pretty fast. @CarlCollins could you elaborate on what you did to get the motor detect to work?

P.S. In case someone else is having issues I would advice you to take caution when trying to flash numerous times using ST Link. According to Carl that can burn up the DRV chip if done several times in a short period of time. I think he said something like 15 times in a 10-20 min time period would be dangerous (lucky I didn’t fry the chip 2 nights ago haha) I’d be happy to elaborate more on a specific area if it would help someone so please don’t hesitat to ask. But for now remote is connected and the motor responds as you would expect.

I guess that means at some point soon I’ll have to start figuring out how to set up the board for the “hybrid” configuration using FOC at low eRPM and DLBC at high eRPM like how @mmaner has mentioned he uses. But in the mean time I still haven’t been able to go tide the board because of the rain we’ve been getting. I’ve never hated the weather as much as I have since I got my board working a couple weeks ago hahaha

@RHill051 Thank you so much man! Glad to help For the motor configuration part, I’ve done the following I reduced Motor Max to 50A from 60A Reduced Batt Max from 60A to 30A and Batt Min to -12 from -60

selected the motor type to BLDC and perform detection. After that, I adjusted the Pulse of Remote as per the remote type>

I hope this helps

i know you said the issue was solved, but if anyone else has this issue, heres another thread sort of like it?

So technically the board works (sort of)¹ but I was trying to update the firmware using both the Ackmaniac tool and the VESC tool but it fails to flash… I created another thread https://www.electric-skateboard.builders/t/trouble-flashing-updated-firmware-on-focbox/71011 to try and get some more advice on how to get the firmware updated.

¹ So I was riding the board this evening and all of a sudden the motor cut out… It didn’t completely die, it was moving really slowly but then after a few seconds it came back to normal. Not sure what was going on. I’m afraid to try riding again lol
