I replaced 12x 12v batteries in my UPS stack this weekend and ONLY insta-welded two connectors. (lemmy.world)

I see this as an absolute win. Be careful, folks. Just because it's DC doesn't mean it won't cause serious damage.

Edit for Clarification: When done correctly, the batteries should not arc. My problem is I did not wire the array correctly the first and a-hem second times. It only cost me one battery, which is a lot cheaper than a trip to an American ER.

Oh no. Half of this post is me making fun of myself. Mistakes were made. When you have a large array of batteries, it's important to wire them up correctly when replacing them. I definitely closed the circuit on some of the batteries when I shouldn't have.

I see how it could be confusing, and in the spirit of sending the correct message, I have added a clarifying edit.
