Archived: the OG noob question thread! 😀

[wafflejock]

I made a calc that should roughly give the right values if you know the diameter and mounting distance (center to center between pulleys) https://jikph.csb.app/ also can use a string to wrap around then measure the length if you have it mounted usually just buy a couple around the right size.

[wafflejock]

Back out mounting screws make sure they aren’t plunged down into the coils, not sure how it is with these motors but happens a lot with quadcopters you screw in too far or too long screws can scrape enamel off the coils and make things short internally (just guessing though still, something to check)

[tipsy]

Can you measure the resistance between the phases? A to B, A to C and B to C.

[Edratuom]

Thanks for the suggestion, which screws are you talking about ?

@tipsy I will need a multimeter, ordering one right now. I will report back when I get it. I knew I would need one at some point. Thanks

[MysticalDork]

@hypocist

Will that fit to Caliber trucks?

I don’t have any Calibers on hand to measure, unfortunately.

@hypocist

also, what fit u do between mount and clamp? 1mm on diameter is ok?
(Should I do a 29mm?)

You should make the fit as tight as you possibly can and still get it on there. So no, I think 1mm is WAY too loose. I’d go with like 0.05mm, and see where that gets you.

[JoelM]

Possibly bearing?

[wafflejock]

I was thinking the ones you have pictured in A, the ones for B should just be helping to hold the can on I think and shouldn’t run into the coils at all but the ones that come in from the top/bottom of the cylinder usually don’t have something to stop the screws/bolts from being too far screwed in.

Noob question! hahaha.

Can somebody explain different battery configurations to me? I am trying to decide which to go for for a custom board I’m going to build. I’m seeing all sorts of battery configs like 10s6p, 12s3p (I think) etc.

To give you some more information about the build, I’ll be using 120mm wheels, 6374 190 kv motors x2

Also need to decide -
which VESC to use
gearing

Any help would be great! thanks a lot guys.

[tipsy]

Decide on the deck and enclosure first.

[b264]

Do you want high reliability? Low weight? Long lasting? Higher resale? Longer range? Smaller size? Better looking? Ability to use in arctic cold? Safer? Higher top speed?

Pick only 2 or 3 of those that are MOST important to you.

What’s your budget?

[b264]

Also like @tipsy mentioned, you’re likely going to run into big problems this way.

Try this

Archived: the OG noob question thread!

If I could be of assistance, it would be to choose your items in a certain order. Don’t choose anything else until you’ve chosen your deck and enclosure. Because you need to know if it will even fit. Enclosures are much more difficult than you think, and you need to know if flexibility will be something you design for, or not. So go in a certain order, along the whole way making sure you choose things that are compatible with each other. helmet deck + enclosure (flex?) battery (flex?) ESC(…

[Fishtaco]

Thanks for asking questions! I’m not sure of the dimensions of the deck yet, but I’ve asked a couple of questions. I’m in early stages of planning for the board.

I may use a full carbon fibre deck with what I’ve been told is tonnes of space. The store told me it can fit “720 WH of battery” within the enclosure.

I like going for long rides, so range is important to me. High reliability of course. Highest speed I’m probably looking for is around 55-60km/hr for a bit of a rush. I’m not sure what better looking has to do with a battery, it’s hidden all the time, isn’t it?

edit: as for budget, it’s going to cost me an arm and a leg anyways since i’m in canada. go big or go home (within reason)

[b264]

First measure the battery tray and let us know. I’d say to use metric but you’re in Canada so you probably will already.

[Fishtaco]

I figured a bunch of you guys would want one. I’ll see what I can do, for now I’ll delete that - I’d like to have some things put together for my board before everyone beats me to it.

I’ll get some measurements!

Battery Basics for Beginners Wiki [Serious]

I see the same question being asked by many newcomers here so I would like to shed some BASIC info on batteries used in esk8, notation, configuration, ratings, etc. Battery Notation Common battery notation you keep seeing or will see is a (XX)s(YY)p battery with (ZZ) cells: XX is the number of cells you have in series ( s ) type connection. YY is the number of cells you have in parallel ( p ) type connection. ZZ is the actual battery cell type used. At the time this article was writt…

Hope this helps man!

[Fishtaco]

Oh for sure @Venom121212 I understand that the numbers are series and parallels. But what benefit is there to change up the numbers of each?

[bwahl602]

What are your motor min and battery min settings

[Fishtaco]

@bwahl602 that’s a little beyond my knowledge at this time!

[bwahl602]

What Vesc are you using? They are settings you configure.

If using an ESC, you can’t configure them. This was the reason I transitioned to Vesc, tunable brakes

[BluPenguin]

To answer your question, S count in a pack increases voltage, P count increases current. I must ask first, how much do you know about electricity, batteries and motors in general?
