Two VESC's assembled! Just need to get some headers/connectors and a programmer and im all set. Z5JQ0EgvMs8 Here's a timelapse of assembly, bit more me in it than I was planning and unfortunately my camera's battery died before I completely finished but it turned out well. close up of the...

The PCBs I got had those pads bridged, so the solder flowed into the area between and makes those two sets of pins bridged. As far as I know it should be fine (always double check the schematic though) I believe with the drv8302, that additional number is batch/manufacturing codes, although I...

Working on a couple VESC's for my upcoming rebuild, so far I have the MCU and motor driver on but for the rest of it I plan on taking a timelapse video of assembly. I've been using a hot air reflow station and a solder paste dispenser. unfortunately the dispenser is a piece of crap so ive gone...

well, looks like nkon is shipping to the US again, 30 euro shipping through Fedex. I need about 60, which works out to around 4.75 a cell shipped.

any recommendations on where to get the Sanyo NCR18650GA cells in the US if nkon doesnt ship here anymore?

Hey, Can you put me down for a DIY kit shipped to the US? Can't wait to build a battery pack for my longboard and this will be immensely helpful.

Is there a peak discharge rating for any of these cells? Or is it a solid "dont go above 10A discharge" for these? Looking to build a battery pack (10S5P) for my longboard and as of right now these cells would be perfect for everything except the initial stall current/large acceleration.

That adafruit charger is meant for single cell applications, its a boost converter and not a buck converter. Also 2.5A should be plenty fast for charging a phone.

Do you have any problem with the enclosure and the board flexing (even remotely?)

im not saying that the hobby ESCs are garbage or the VESC is the only option. Stating the only way to overload an ESC is through improper gearing causing heat doesn't make any sense at all. Its missing the power aspect, you can have the wrong gearing and it will still work, its when you try and...

It's coil whine from the inductor. It's possible that the rest of the circuit the inductor is part of isn't stable anymore, causing the whine. The fact that the VESC doesn't work might mean one of the IC's "died" to the the point where it almost works but is functionally dead.

Everyone here realizes that the ESC's we use are all built the exact same way right? an airplane ESC doesn't have a different FET configuration vs a car ESC......plus we extremely overload any ESC unless it's the VESC for the most part. These hobby ESC's are designed for vehicles weighing 10-30...

its possible that you blew the ESC through too much current. While I wouldn't say the specs on these motors are dead on accurate, if we take the peak power of the motor (listed as 2665W, then at start up there is the potential to draw anywhere from 105.75A (at 4.2V * 6 cells) to 138.8A (3.2V * 6...

I just ordered parts to build a couple V4.10 boards. Ordered 10 PCB's from Smart-Prototyping and enough parts to build 2 boards. ill post an update when I get the boards assembled (personal SMD workstation at home, awww yeah). If the boards work I might also build out the other 8 VESC's that I...

Talk about quick response! i have a nyko kama nunchuck, Turnigy Trackstar 150A GenII ESC I've never really used cruise control, and I don't want to completely blame it (correlation not causation kinda thing). But the run up to the event was i tried cruise control and it worked for about a...
