Building your own battery costs more, but I enjoy working with and studying with battery tech. If using this build as inspiration, consider LiPO’s and a balance charger for cheaper but heavier batteries.
Don’t try to solder 18650’s! The heat will damage them no matter how fast you try to do it.
Electric skateboarding is not cost efficient or safe compared to electric bikes. They are more of an portable lightweight commuter and fun ride. If you’re looking for a car replacement, I would look towards DIY electric bikes.
I have not tested 3D printing motor mounts or pulleys yet, but I would like to. There is carbon fiber filament that apparently holds well? PLA is heavily not recommended. You could also mill your own out of aluminum if you have the tools. I will try this on a later build.
Obviously, wear a full face helmet.
