Building 1s10p stacks

it is weird how blog entries for off the grid contest disappear. I was documenting how inspired by unagi e scooter batteries, I built a 1s10p unit from ten 18650 batteries from amazon.com and soldered them with nickel plates, used a juicer to charge them, you can charge three stacks easily with s good automated juicer and use a ready 4 volt to 36 volt dc2dc converter cable. That simple.

I think there were more than a few doubts and objections to the methods employed, but I think it's worth a discussion as to why, how and what was going on, and maybe what would be a better approach.

Hi, this isn't how battery packs are made. There's no comparison between this, and any normal battery pack. The cells are not soldered in battery packs. Also, I've not seen any Amazon link that supplies matched cells. How do you know that the batteries perform near-identically, and are identically charged? What if one cell was a customer return? What happens when a cell in the pack overheats? If the aim is to replicate a scooter battery, it could be better to buy a scooter battery, since they will have had to consider all these things.
