Today received my PCB’s of VESC and the rest of the parts. Off to soldering


Did some soldering but did not managed to make main cpu work I guess my programmer is bad or etc ordered a new one.

Here is how power stage looks (It’s uncleaned pcb straight after soldering)


Are you using a hot air blower or reflow station? If you’re gonna be doing a lot of surface mount soldering, it will save you sooo much time and your connections will be much better.

Solder paste and a hot air blower is the only way I would do it

Yeah, I did with solder paste and hot air, but my hot air station is bit crappy and still learning with solder paste dispensing plus my solder tip is shitty.

P.S. I havent done any smd work for last 6 years

Oh okay gotcha. I understand haha it was hard my first time too :stuck_out_tongue: and I had a pretty nice one

Gears arrived today


Today, have redone the VESC board to single unit and better version of it.

This is a “Balancer” part of my upcoming BMS which will balance each LiPo pack separately from all 8 packs


Wow this is pretty impressive. Congrats!

What battery are you planning to mount?

I’m doing a pretty similar build bmand I’m not sure if I should go 12s4p or 10s5p

I will be going 12s4p swappable or 12s8p

How much did you pay for the 6384s?

Not much 89£/each

Today I have bought the batteries for 12s4p, Nano-X controller for a temporary solution before I make my own, and will be buying two FocBox’es also for temporary to test the drivetrain.

After Black Friday my batteries arrived

Not Big BOX…


Wow! You are going crazy with these batteries now. What kind of range do you expect?

Worst case scenario 40Wh/km = 1209.6Wh / 40Wh/km = 30km Best case scenario 10Wh/km = 1209.6Wh / 10Wh/km = 120km

But I am still thinking of building two swapable packs of 12s2p


Today I received my XT90 connectors (they are the same brand as the ones on Turnigy Graphene batteries) and two Steering Dampners.
