Archived: the OG noob question thread! šŸ˜€

cool thx. I heard something hit my deck after climbing a hill and my board powered off. it turn back on with no problems no visual damage but i was pretty close to cutoff end just wanted be sure that cutoff end does not mean power down which i knew already but it was one of those ā€œwhat da hellā€¦I wonderā€ moments.

If I use a Battery with 60A Max Discharge with two 4.12 FSESCs running solo with split ppm (by using two receivers), do I want my battery max on the VESCs set to 30A each, since Iā€™m running them in parallel? Also, how do I choose the right battery minimum value and max/min motor value?

Battery: 10S3P 60A discharge
VESC: 2x Flipsky VESC 4.12 50A continous
Motor: 2x Flipsky 6355 65A Max

your logic here is sound

i would want to know what cells are in your pack before hazarding a guess

Ive used plastic wrap (cellophane) before to help shape the JBweld around my VESCs in my enclosure, but has anyone tried to use plastic wrap with silicone?

Iā€™m thinking the only way to compress the internals of my enclosure to give a proper seal/flat top to the silicone I pump into the enclosure is to bolt it to the deck, but I donā€™t want to mate the deck and enclosureā€¦ Id rather it be two pieces :thinking:

What materials have people used to help squish silicone down without it sticking to the opposite surface?

start hereā€¦ there is a bit on catalyzing siliconeā€¦

not water IN itā€¦ water on your pressing agentā€¦ and anything else you donā€™t wish it to stick toā€¦

welpā€¦ there is my some and total knowledge of catalyzing siliconeā€¦ iā€™ll let others converse

I got a quick question.
If people have issues with max erpm braking/lockup, why donā€™t they set much higher erpm limits if their esc can safely handle a value much higher than it is set to?

If their esc canā€™t, why not just limit your max duty cycle in ppm to less than the 95% so that you never hit the limit, and fall at 35 mph?
I would like to prevent a lockup mid ride as much as possible, and my understanding of erpm and how it works in your esc confuses me.
Would love to know more about this

Imagine your board hits erpm limit at exactly 20.00km/h. Now imagine you set all those limits you say. Now go down a steep hill that would get you to that speed even with brakes engaged and youā€™ll see why it gets scary and fast

Is there any support at all for tizen os? Any app, bluetooth module? Anything at all?

Split PWM (ā€œPPMā€) is one receiver. Dual PWM is two receivers

I already asked this before think but forgot to bookmark the answer and nothing shows up when i use the search function :roll_eyes:

How does one find the KV of the motor if you donā€™t know it? i believe there is a way to do so on the vesc tool? I also think there is a calculation you can do but i forgot.

divide or multiply the erpm by the pole countā€¦ or something equally arcaneā€¦

Run the motor up to maximum unloaded RPM, measure the RPM (vesc tool can do that) and write it down, as well as the supply voltage at that RPM. If itā€™s ERPM that youā€™re measuring rather than physical, (I canā€™t remember which one vesc tool reports) divide by the number of pole pairs in the motor (usually 7 for our outrunners). Then divide RPM by voltage, and you will get a rough idea of the KV.

Thanks!
I have 4 motors, i know 2 are 170kv the other 2 200kv, i know that the latter is lighter, but just wanted to make sure since they have no markings on them so we donā€™t know which is which 100%
