nice vid!!
Hey just wondering, did you typo your receiver code?
int counter_checksum=0;
counter_checksum = ControlValues.ValY;
if(ControlValues.upperButton == true) counter_checksum++; <<<<
if(ControlValues.upperButton == true) counter_checksum++; <<<<
if(ControlValues.checksum == counter_checksum)
{
recievedData = true;
}
did you mean to check upper and lower button instead?

Hello i would really like to make my own i just dont have the tools skills or time to do it would it be possible for me to buy one like this of of you i would really like to come in contact with u.you’re work is awesome and i really support you Best wishes: Addi
How much it costed you to make

It is impossible for your board to be 5000w with a 12s3p 30q pack unless you are planning on destroying cells running a 3P 30q pack at 100A + discharge…

Im not the only one thinking this then, they must be running very hot.

is it possible to get a full partslist?
Awesome build Pryside! i’ve got a lot of inspiration from your build and would love if you and everyone that reads this would give me some feedback!

Hey @Pryside, I have an ESV based on 4.12 in the standard design, where should i solder the tvs? Parallel on the back on plus and minus?
the motor mounts are from torqueboards
have a look at the other videos from him, there is a good descritpion
sorry, forgot the “charging”. Its the charging rate in Km. Because I have a quickcharger with 400W that charges the board in an hour. The charging rate is 40Km of range per hour
jupp indeed, that is a typo. I will fix it. the upper and lower buttons dont get used anyway thats why I propably didnt notice it while testing. Thanks for the comment!
A TVS on the Antispark wont work. The voltage trancients get created directly on the vesc and should be eliminated before even reaching the battery. Thats why I said in the video the tvs diode should be mounted directly onto the vesc pcb where the battery wires go in otherwise the tvs will have no effect

Yeah propably that sounded a little full of myself, it wasnt inteded that way. I called a lot of stuff like the Firefly Remote from Solidgeek and a ton of other components awesome and great too. I think I called my own stuff one single time in the video great and I dont think its a bad thing to be proud of your own creation that I spend so much time for and to express that, its a very normal thing that people do. Be proud of your work.

Not that easy. I could build one but that would cost 1300€ in parts with charger and all. And labor is around 80h to fully build one again so around 2500€ would be the cost of one.
No its not healthy but also doesnt destroy them. The 30q cells can widthstand a 35A burst quite easily. They are capable of 22A constant discharge and in their lifecycle tests they run them with 22A constant. Many “30A” or “40A” cells out there have a similar internal resistance so other than faster degradation this doesnt really affect them negatively. Its also a power that I almost never use only when accelerating on a hill. I usually stay below 1.5kW when riding and peak above 3kW for maybe half a second. I also only charge to 4Volt/85% and discharge never below 3,4V/15% And after around 40 cycles I still have full range and no cell is ever out of balance.
jupp, right there where the cables meet the pcb. the body of the tvs can be right above the current shunt also if you have some space, try maybe soldering a good low esr 62V cap directly on the board, also helps a lot.

the P6KE-51A will maybe work with 11S and below but not 12S. It has a breakdown voltage starting at 48,5V this is no bueno when you have a battery voltage of 50,4V fully charged.
the p6ke-200CA has a breakdown at 200V and wont help anything with your 60V+ voltage spikes.
47CA has a breakdown at 47V also not usefull with 12S
really use the 56CA or 56A as I recommended in the video they are the only ones with a breakdown closest to your 50,4V

You can be proud, Leo. At first I thought the same way like @janpom about you, but If you create or invent things you have to mention that it was your idea and your try. Everyone does it and if not someone will steal your ideas and make them their own. In this forum are so many very impressive builders who exchange themselfes with others for building better boards and to eliminate possible mistakes for being save in the workspace and finally in the streets… Im no specialist in electronics, but i learned a lot in here and i can tell you the only mistake you made is just to solder your batteries instead of spot weld them(i think i saw that in your videos). I know from the batterie freaks in here that soldering will damage your cells and the construction is not very reliable. Please look @pjotr47 ! He is a real Battery god and a specialist all the way for maximum power. peace
