I got my battery pack from this group buy: https://www.electric-skateboard.builders/t/also-usa-10s4p-samsung-25r-190/12458/146
So, I had my battery pack for a while now. Since I am still waiting for my VESC to arrive, I thought I would shrink wrap the pack since I was not 100% happy with the fake carbon tape solution. Technically everything works fine with this pack. I just wanted to stress that here. Just the wrapping I wasn’t to fond of.
So I removed the tape:
On the other side is layer of plastic sheet to stabailze the BMS, switch, etc. I wanted to get rid of that in the process, to save some height to better fit my enclosure.
Without the plastic sheet:
I got my shrink wrap today and I wanted to see if it fits. And here is where I messed up:
I put stripes of aluminium on either side within the shrink wrap testing to further stabilize the pack horizontally. When I moved the pack it shorted and burned a whole through the aluminium. I am glad that nobody got hurt.
My stupidity is not in question here. I know I messed up. I was wondering first, what went wrong, since I always thought that aluminium does not carry electricity? And second, where do I go from here? The pack still turns on.
I obviously have to solder the cable back on. But, is it save to still use it like that or do I have to fix something? And if so, what and how?
