/diy/ - Do It Yourself

Kind of...

I took 2 small electric skateboards and made a 500w dual front/rear board. I ended up using the vruzend kit to rebuild the dead battery I had. I have spent about 160$, minus the battery kit because I used 7 out of 50 sets and will use most of them on other projects.
Donor 1 70$
Donor 2 60$ 1 dead cell
Longboard 30$ new
Vruzend 40$, 7 out of 50 used, 7s1p 29.4v ~1.8ah

Considering changing to a dual motor esc so I don't have to hold 2 controllers-65$
But at 200+ I can get a Chinese 500w dual hub motor for around the same cost, 230-250

How can I connect all these FUCKING cells in series without a spot welder?
Solder doesn't stick
Hot glue is momtier
Tape won't hold
VKEKEND won't sell their updated SHIT and it's like 40$
I'm too mad to take another picture but they're in the bottom left, standard 18650s
