content: 4 - Molten metal raining all over the batteries.5 - Terrible connections.6 - He should have called Electroboom, Photonicinduction, Plasma Channel, or anyone else with some electrical knowledge instead those rednecks who's capabilities were just screaming "Woooooooo!!"

content: Offtopic entered the chat!We all hate these junk channels but when you have little options in life you need to take any opportunities.I definitely prefer crap videos (Which I can skip) than scamming centers or mafia stealing kidneys.

content: That was a fun video seeing what insane amount of current are capable of. You always tend to see such high currents supplied for short periods from battery banks, not constant DC.I was hoping he would also try 100 in series, but then again having 1000A at 1200V DC sounds rather terrifying.(That switch of his would never be able to interrupt that)

content: Quote from: bdunham7 on October 05, 2023, 11:00:01 pmScariest thing I've ever seen on YouTube was someone who wired a thousand or so 9V batteries in series, arranged in a tightly-packed array. Car batteries would probably be safer.

content: Quote from: DavidAlfa on October 05, 2023, 11:25:26 pmEasy to criticise people who are having fun AND providing happy, cheerful education. At least he MADE the effort, and the video, that’s A LOT of work. I thoroughly enjoy his channel.Being overly pedantic is irrelevant in the context of his style, he’s FUN, he’s dangerous and takes risks. His old YouTube style is infectious. Good for him!)

content: We used 50 car batteries shorted out to do butt welds on steel continuous sucker rod for oil wells.This is about 1-1/2" rod that was clamped down in a jig and pushed together while the juice was on. Ends would mushroom and then you grind that off. Rod is a 0.8-2km long.It's been many years since I was involved, they were welding trucks since this is a portable thing, the welding was done on site.To determine if the weld was done properly, you had to look at weld current and integrate the power verses time. Big shunt was used about 10,000A was the top you could measure the weld over time with a Scopemeter.I used to freak out about the hydrogen evolved in the battery box but it was never a problem. Battery temperature was a huge factor, they don't do well in winter temperatures so you'd have to keep the truck (battery bank) indoors and warm before driving out to site.The contractor was custom we designed it, absolutely huge, hydraulic actuated.
