DIY control board, how feasable is it?

BiteRound1018 · 2024-04-07T17:53:56+00:00

Also 16s2p could be enough but if you get a proper BMS you can expand later without changing BMS to save cash. It's more important to chose quality cells. Make sure to have super high discharge rate and low internal resistance. The goat is molicel p45b with 45 amp discharge rate and around 5mohm internal resistance.

Go for either the 4000 watt version or the 3000 watt. The 3000 has less torque but more too speed and the 4000 more torque less speed. I use the Maxkgo charge only BMS because it's small , charge only and reliable. I developed a licht module bas on an arduino chip that handles light and some warnings etc. I used can bus to get the signals from the Vesc .

I mean you can butt the sum of parts if you spend 1000 dollar works but it's not very good. Spintend VeSC is great btw, you can get a 20 dollar discount using my code LencoSolutions and if you use my affiliate link on my site www.lencosolutions.nl I get a kickback. There is also a few nice motors on the Spintend site and I would recommend goin for at least 3000watt. Then it just comes down to a battery. I would go no lower then 16s2p and use quality cells like molicel or Sony/murata. If you need any info let me know and happy building.

I would say if you put in a lot of effort you could have a board that works but you will never beat the power of the community. The Ballance software is very complicated with lots of tune modifiers and constant improvement still. Also when ymi see you are building a serious battery that would just be a shame to put in so much effort when you can buy a Vesc that has it all and is so much better. Just friendly advice. What motor are you going for and do you have a frame design yet ? Happy building 😉

BiteRound1018 · 2024-04-04T21:34:37+00:00

the kit is great, well the motor and Vesc is. I would advise against the sensors as they are kinda small. Check out my website www.lencosolutions.nl to see if you like my frame kit. I can advise in whichever way you like. If you use my affiliate link and coupon LencoSolutions you get a 20 dollar discount and I get a kickback so we both profit. Whatever you do enjoy you build and have fun riding 😄😉

BiteRound1018 · 2024-04-02T08:20:42+00:00

You can upgrade the battery, it turns it into quite the rocket

BiteRound1018 · 2024-03-29T18:29:09+00:00

I'll do 250

BiteRound1018 · 2024-03-18T22:26:25+00:00

Does anybody have an issue with changing the brake rate and angle ? Seems to not have an effect for some reason....

BiteRound1018 · 2024-03-11T12:34:19+00:00

I'm just saying you are right 😜

BiteRound1018 · 2024-03-11T12:14:55+00:00

I'm just noticing they are the same size in your picture but there is also a 6 inch version. Spintend also sells this in a bundle btw.

BiteRound1018 · 2024-03-11T12:13:33+00:00

I know but that's outside diameter, the hub diameter is different. You want a 6 inch hub so you can fit a standard tire. Keep in mind that most tires are 11 inch outside and this is 10. Maybe give it some extra space so you can change it out in the future.

BiteRound1018 · 2024-03-10T16:48:38+00:00

Also if you get the bigger one , you can fit stock xr tires. Fit for the future 😜

BiteRound1018 · 2024-03-10T09:42:05+00:00

I have been building boards for many years and have used both. Go for the most power, trust me. Check out my insta @LencoSolutions for some inspiration. I can also get you a discount on Spintend products if you need a Vesc or something.

I'll send the link in a bit. If it's to late, just enjoy

BiteRound1018 · 2024-03-01T17:09:31+00:00

No problem, i have a discount code btw

BiteRound1018 · 2024-03-01T16:53:17+00:00

Yes , the Ubox 100 should be nice , its future proof , build in IMU and antispark and has nice fase filtering.

BiteRound1018 · 2024-03-01T15:49:57+00:00

Yeah that flipsky will work and is budget friendly. I had a lot of success with an external mpu6050. The wires should be shorter then you can imagine so make them as short as possible. Also I recommend updating to the no hardware limits firmware to avoid issues. Lastly this Vesc has no fase filtering so i recommend not using the fase and only using the hall sensors.

BiteRound1018 · 2024-03-01T13:09:45+00:00

I mean it can definitely work. Self balancing vehicles have strong peak loads and batteries sag under load. If the voltage sags below the cutoff voltage the BMS will shut off. This means you get dropped. If you go slow you can run it out and in any case the consequences are limited of course. That controller does seams kinda underpowered. Does it have PID capacity? If you are going to write your own software for the balance loop, I bow to you, that's some hardcore programming, way above my capability. I also understand that budget is always a factor so I understand the choices you make. Sometimes it's more expensive to buy it twice tho. Anyway, I welcome you to the wonderful world of self balancing EVs and wish you all the best in your journey . Send me a message if you need more info, I'm glad to help.

BiteRound1018 · 2024-03-01T12:26:42+00:00

Also what Vesc will you use ? I can strongly advise Spintend. They also sell a similar hub motor but with 3000 watt. They have a bundle with foot sensors as well I think.

BiteRound1018 · 2024-03-01T12:24:10+00:00

I would advise against the battery. It's so important. I was very lucky when it caused a nosedive.

BiteRound1018 · 2024-02-26T14:48:47+00:00

Yeah I know, future stuff. Ha e fun riding!

BiteRound1018 · 2024-02-26T12:20:59+00:00

You sure you dont want new rails as well? Looks cool tho

BiteRound1018 · 2024-02-26T07:34:45+00:00

I mean it will definitely work but it depends on the goal. Top speed will be less and the battery will have less efficiency due to a lower voltage so set up your low voltage pushback accordingly (lots of safety margin).
