Saw this on my FB feed. Must hurt like hell.

Yuck, that looks nasty!
There is a time element to it, not just voltage & current.
I used these to connect an SBS inverter to 480V (DC/DC boost) LG RESU-10H battery:
I unplugged, but them my palm slapped back against the plug prongs fed by inverter capacitors.
I instantly let out curse words, but it had no lasting effect. Local circuit in and out of my palm.
Compare to when I brushed against 480VDC from PV while kneeling on damp ground.
I squealed like a stuck pig for a couple seconds before formulating colorful English words.
That shook me up, but no harm. I rested a bit before cautiously resuming work.
Both incidents were as brief as humanly possible.
I think something kept him in contact longer. Or, his hand had lower resistance contact. My hands were dry.
[Edit - we know understand the burn incident linked by OP wasn't electric shock, it was an arc, plasma burn and/or arc flash. Two 48V batteries got connected backwards, which is 96V nominal of battery that drew an arc. Like my buzz box arc welder except instead of 230A it had 1000's of amps available.]

I saw that one the other day. Looks like a burn, probably arc flash. And I sure hope he sought medical attention. It's a serious wound with significant risk of infection and probably some localized tissue damage. Hope he's OK when it's all said and done.

It's an eye opener for sure. I shorted out a single 18650 cell in my office ( was taking apart a 60v pack), was like lighting a roman candle in the house. Then making busbars I shorted a wrench to my wedding band, like Hedges is saying, the ring heated and glowed red in a nano second and luckily cooled as fast (hardly burned me ). I've learned to tape and cover everything, Can never be too Cautious
Get ye to the ER, stat!
Proper PPE working with over 48V…
And never use both hands on a circuit.
Nothing is easy, pay attention, or there will be a bill…
Focus on what will happen NEXT when you do something.

I saw another post from him on Facebook where his hand is now mostly healed

I feel like a Wills latest video might have even been in a round about way in response to that video circulating around the web so virally over the last 3-4 weeks or so.
Lots of misinformation going around about it and it probably scared a lot of people away from DIY.
You know how the telephone game works, even two to three people (posts) away from the initial person and you're already conflating the story and embellishing things.

Some times it doesn't kill you, but if you are in a ladder when you are shocked and fall off, the fall might kill you.

"What doesn't kill you just puts you in the ER."
just awful!!
For educational purposes for the DIY crowd. Film a reenactment and post it here.

Here is the source of the picture - 48vdc -- arc flash burn - AGM batteries - 4s3p - 12v --- Directly connected negative to positive while hooking in parallel
Thank you to the well wishers. I appreciate your concern. I am recovering from the arc flash burn. Blister has gone and I cut the dead skin away and it looks good. Brand new pink skin . I managed to keep infection out. In the first few days I went the er twice for pain. Each time I got a shot of morphine. I have not had to have anymore pain meds. I have quite to high tolerance to pain Always have.
What he did -
This was a mistake made by myself while hooking batteries for solar system. I have 12 12v 170Ah glass mat batteries. These are in series of 4 batt. To each bank which is 48vdc. After putting the banks in series I was in the process of now putting them in parallel. I went directly from negitive to positive post. This was the mistake. When going parallel all the positives go together and same for the negitives. And this is the result.
