After I found this site last summer I got a lot of inspiration to try to build my own Yes, I read a lot like I read most people do - but what I learned the most of is actually doing the build, trying the parts and failing. I would have done things differently if starting now. I will try to mention some of the things I would have done differently. So let’s get to the build
Motor, trucks and wheels
First I bought trucks, motor mount and a 6355 190 kv motor from Enertion. I don’t like the colors much so I may repaint them someday. Or not This was november last year. You may notice that I changed the wheels to some original flywheels
Mounting those circlips without a proper tool demanded good stamina and a good mood
##Battery The battery was not that easy to get like I wanted for a reasonable price in Norway. I tried some options in Europe for a 10s3p pack - I wanted a small one for my small board I had in mind. In ended up getting really expensive. Luckily I found a guy nearby with a spot welder that he had used for some eBike and similar projects.
LG HG2 times 30. Should probably have bought a few extras, but it turned out ok. Unfortunately nkon.nl was not willing to ship to Norway so I found a local webshop selling batteries for ecigarettes. More expensive, but only option I found reasonable.
Specs written on the box. Glued them with a hot glue gun. Spot welding Finished welding the nickel strips. Note This is not the best design as I see it:-
I should have soldered on 10 AWG cables for the plus and minus end point on the nickel strip ahead of spot welding. Not smart to solder directly on the nickel strip afterwards and it also builds in volume.

I would have used a different wiring setup. Me and the guy helping me discussed it a bit and the reason for doing it like this is to have short battery cables. However then I need to isolate between the two rows of battery, and it the battery pack also increases in volume.

As you will see further down the balance wire chaos was a bad design decision. It was just done like this with too little thought.
Look at how @whitepony did it with his 10s3p here https://www.electric-skateboard.builders/t/carbon-jet-spud-freebord-bindings-single-vesc-10s3p-lg-hg2/5805/76?u=oyta That is a nice battery pack.
Adding balancing wires times 2 - necessary? I wanted it to be able to measure the voltage of each pack in the series.
Messy! I’ve definitely improved my soldering skills during this build. A lot of connectors, cables and joints have been solder. Some quite bad - some redone - some good. The photo shows the batteryback on the board with BMS, VESC6 and other stuff.
I have more coming, but need to go now. Next up is making the plate and more. I will post some more later.
