    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Just an update on my issues with thermal limiting on my BBSHD: So after a longer ride, I've discovered that not only is the Controller temp sensor far too restrictive, but the motor-only 'Temperature Sensor' option is also too limiting. (the 'All' setting I tried at first kicked in almost...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Quick update. Changed Temp Sensor to 'Motor' from 'All' and was able to climb hills as before - no cutouts. Temp display (Range) got to 125-130F at the same point as where it reached 165F previously - so I'm presuming that the controller temp was the one triggering the high readout before...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Daniel thank you so much for doing this treat work! As I'm running my BBSHD with a 12S pack, I've been desperate to find a solution to premature LVC cutoff - it's truly painful to be restricted to 11A towards the end of a ride when the battery pack still has 50% remaining (~43V). So I just...

    BBSHD Voltage Problem Firmware Update & Instructions

    Thanks tdirider. I can't think of how you could modify the voltage read circuitry in a similar fashion, as the voltage read is likely taken directly from the battery in that feeds the motor drive FETs.. Am I missing something? HOWEVER, you did just make me realize that perhaps a simple 50%...

    BBSHD Voltage Problem Firmware Update & Instructions

    Not exactly the thread topic, but there have been multiple comments regarding low-voltage cutoff and/or current restriction for various firmware versions discussed here, hence my post. If it would be better served as a standalone thread, I'm happy to revise. I've got two BBSHD bikes, each with...

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks jbalat. Actually I do pedal often in the 95-100 cadence range for more than brief periods, at least I did when I was younger (!) Approx math above implied a max of 94, but really need another datapoint on max powered cadence without using Field Wkng to know if it could be higher (36v...

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks jbalat. So looks like the latest mbrusa version does Field Weakening just as well - 117 cadence vs the 115 from your prior test. And I think my approximation of what max cadence w/ Field Weakening would be for my 12S battery was wrong. I had taken 12/14*128=110. But if you're getting...

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks jbalat - very helpful video! So you're getting these results for max usable cadence: 36v Core w/ 36V battery (10s): Standard FW: 92, Experimental FW: 115 36v Core w/ 48V battery (14s): Standard FW: 95, Experimental FW: 128 So this would suggest that with 44V(12s) battery, those...

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks ilu. So you can get motor support at 110 cadence without Field Weakening on 14S/36v motor. So with my 12S battery, that would imply max cadence support of 12/14*110 = 94. Hmmm a bit lower than I'd like.. It's strange that it's a very sudden limit after that - would suggest that's the...

    New "TSDZ2 Torque Sensor Central Motor"

    Trying to get more clarity on max cadence support for the TSDZ2 so I can choose between the 36v (higher KV) and 48v (lower KV) motor core options to pair with my existing 12S9P battery setup (44V nominal). I want to be sure I have power in the 90-110 cadence range while still optimizing...

    Active pre-charge/inrush control

    Thanks so much for posting the add'l info Manny! Been trying to figure out if one of the LTC ICs would make it a whole lot simpler to design/build a reliable pre-charge/inrush control. Glad to see you've had success with it. Any chance you have a schematic you could share? I'm not sure my...

    Active pre-charge/inrush control

    Hey Manny, I think your post got overlooked, but I'm guessing many of us would love to see your schematic for this. Can you also give a little more detail on the application and how it's working for you? Thanks!

    OpenSource Remote for VESC ArduBoardControl

    Has anyone tried getting the VescUartControl library to work on a Simblee (https://www.simblee.com/)? Given Simblee's built-in BLE and simple mobile-app programming environment (one app coded in Arduino works on both Android and iOs), it might be the easiest way to just get VESC data displayed...
