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.
Replaced the batteries?
I’m in the process of topping up the water in mine intending to refresh them… but you’ve made me think… I need to check them for deadshorts / opencircuit
And I thought you’d burnt a horrible groove in your finger!
