Noob question thread! 😀 ask your questions here!

What VESC Tool are you using to run motor detection?

On my first build using Ackmaniac’s Extended Vesc Tool I ran into similar issues during detection and I had to set the Duty to 0.10 to get it to run detection correctly

[Chase]

Yeah I was testing it using the bdlc tool. I honestly think that one of the sensor wire bullet connectors has become unsoldered. I’ve seen very similar problems when a sensor wire wasn’t plugged in all the way. I’ll usually just use the front and back arrows to make sure the phase wires are in order before configuring the whole vesc. I tried to do motor detection as well but nothing is solving the issue. One of the combinations of orders of the threes phase wires makes a loud screech for like 10 seconds (much louder than any vesc screech I’ve heard in the past.

Does anyone have a wire diagram for: 10s bestech bms with e-switch. WIth charging port and push to start button

Anyone can confirm that @trampa stickies wheels core is same with abec flywhees core?

[trampa]

Yes, pretty much the same. There are small differences though, nothing that should matter.

Do you have to run motor detect every time you reconect the same motor?

[arcticx7]

Hello, can anyone tell me why using this motor is or isn’t a good idea, thanks https://hobbyking.com/en_us/turnigy-trackstar-1-8th-sensored-brushless-motor-2400kv.html

[Octave]

Its 2400kv, you want something below 300kv

[Andy87]

No, only if you change phase wires for example it can be that the motor doesn’t spin when you use your remote. In this case just run motor detection again and all is good. As long as you don’t change anything in your setup the motor detection results saved in your vesc

And it’s 5mm shaft only. Most pulleys for eSkate are 8 or 10mm bore

[arcticx7]

octave and andy87, what about this one? https://hobbyking.com/en_us/turnigy-sk8-6354-260kv-sensored-brushless-motor-14p.html

[Octave]

What batteries are you going to use?

Edit: you can use this to calculate your speed and erpm

http://calc.esk8.it/#{“batt-type-lipo”:1,“batt-cells”:8,“motor-kv”:260,“system-efficiency”:85,“motor-pulley-teeth”:15,“wheel-pulley-teeth”:36,“wheel-size”:90}|

[Andy87]

Like @Octave said it depends on your battery and your vesc. If you run a hw 4.xx vesc and 12s than better stay under 190kv or go < 10s. You wanna stay alway under max erpm of 60000 with he 4.xx

[arcticx7]

For batteries I was thinking 2x ZIPPY Flightmax 5000mAh 3S1P 20C and later upgrade to 4x, I don’t know yet which ecu to choose.

[legend27]

When i use my spot welder with car battery the voltage goes from 12.8 to 12.7 and slowly rises up, next weld it goes from 12.73 to 12.66 and rises to 12.71 in about 4 seconds. It just keeps going like that. The battery is brand new. It’s a 12V 80ah 700A battery. My question is: is it normal and does the battery still deliver enough power when it’s at 12.67V?

[Andy87]

What kind of board you will use? 6s is kind a low voltage, so your 260kV in this case is not so bad choice.

[arcticx7]

I will use a skateboard with longboard wheels. Ok thanks for the info. I intend of upgrading to 4x 3s batteries later.

[Blitz]

@arcticx7

I intend of upgrading to 4x 3s batteries later.

Risky if you don’t know what your doing. batteries start dying, losing performance, etc, from the moment you start using them. Ask me why that can be risky.

http://calc.esk8.it/ use this like others have advised, Here you can find your ERPM after inputting all of your data. and the limit on vesc 4x is 60,000 stay under that if you wanna be safe.

[Zentaria]

is this right? or doesnt the thick red wire go nowhere on the bms?

[Joris]

Im stilling wondering if this is right before i spark up or break anything

thanks !!
