@MYKC

Is there a complete “how to” on building batteries or do I have to read through the 6000+ posts in the battery builders club thread ?

Somebody made one!

Derelict Robot Industries - 12S4P FlexPCB Build Guide

Whats up you cool cats and kittens. The Robot is busy, so I robbed him blind and took over his build guide plans. The duck’s in charge now. [IMG_20200521_205518] Today we are going to learn about building a “DRI 12S4P FlexPCB Battery Kit!” This thing is as simple as it gets, so even a bunch of knuckle-draggers like yourselves should be able to do it, provided that you have the necessary materials and equipment. Here is what we are making: [IMG_20200522_121135] Build time (inclu…

@thetrueoriginal

It’s coming with helical gears

There’s a bunch of guys here that know this stuff, but I’ll just call on a few:

@Lee_Wright
@Andy87
@rich

Any chance you guys can weigh in here? Thanks.

The loop key(s) on the monster box have xt90s connectors so you don’t need an anti spark.
Trampa has a few diagrams on their website showing various types of connections

Pictures showing what you currently have would help.

Have you considered going with LiIons? You can get a lot more range for the same weight/volume.

Where are you based?

Anyone know if I can use the vx2 pro v4 on v6 hardware? Can I make a converter plug? Or change the plug?

[Halbj613]

so i have a set of carvons v4
and i am having a slight issue with one motor

it makes a slight noise and has slight resistance when turning by hand
then at speed (15mph around)
it goes krrrrrrrr and acts weird

i have confirmed (pretty certain) that it is the stator of that motor
what is the best way to find out what it is and how can i fix

does anyone know what motors they used on the v4 and is it replacable
thank you very much

[b264]

The Carvon V4 SpeedDrive comes in two flavors, Carvon V4 SD R and Carvon V4 SD XL.

Which flavor is it?

Also try the hand test

How to hand-test a BLDC motor [SRO]

Sometimes if you’re buying used, or troubleshooting, and need a quick way to see if anything might be wrong, you can test a BLDC motor with only your hands. It’s not the most accurate test in the world, but catches most problems. [f5c1e17e62e9f244432bf763be93746978c88931%20(copy)] Ensure motor phase wires are not connected to an ESC or anything else. Verify the motor spins without grinding or rubbing. Put a tad of sideways stress on the shaft and push it and pull it (while turning) to veri…

[Halbj613]

speed drive dont think xl
but how would i know?

thanks

will look at the hand test

[Halbj613]

so @b264 i tested the phases and all seem good

a-b was mild strong
b-c was mild strong
a-c was a little weaker but did still brake
a-b-c was very strong

also i noticed on the broken motor it seems that the magnetic field is slightly weaker and the can is easier to take on and off compared to the other side

what is the best way to go from here

i will upload a video of the sound soon

Just interested…

I have a 12S6P Pack with Samsung 30Q.
I have my VESC Set to max curent battery 65A and max motor 85A.
I run two Trampa VESC Six with BioBoards 6374 Motors.

What are your settings if you run a similar configuration ?
I am not sure if I am already maxxed out - I have loads of power and the board feels great… just need some comparison

Also I am still not 100% sure if the configured Current is now for Each VESC or if CAN Connected VESCs will use only one value ?

[Halbj613]

Here is the noise it makes on the bench
It becomes a much a louder weird noise when I actually ride

The little krrr you hear every so often in the video is amplified when riding

Thanks if anyone can help

Really want to fix this motor

Any suggestions on what I can do

Video with wheel on

[xsynatic]

vesc tool is each, unity combined. So you have 2x 65A battery.

[Halbj613]

Please someone help

Really wanna get these working

Carvons v4 need help fixing

So need a bit of help Have these carvon v4 sd and one motor makes a weird noise This noise gets amplified when riding above like 15mph It is some sort of krrrrr noise which is really annoying and loud The resistance is reasonably high in the motor 95mohms compared to 35 on the other What is the best way to work out the issue and to solve it @kook I know you fixed some carvons Did you ever have this issue Thanks a lot everyone Please help if possible

I have one old Street Wing motor which wasn’t running well. It was “blocking” in a small part of the rotation movement, when turning it by hand. Opened it, noticed shaft was loose, so tried to attach it again to the rotor. Put it back together and now it’s even worse, really need to force it when turning it by hand for more than half of the rotation. In the bottom of the stator, there are a few marks which seem to be the rotor magnets rubbing against it, since the magnets also have those marks.

The rotor is indeed a bit angled but I never thought it would have a huge impact. Should I try to mount the shaft again? Any tips?
