Accidental short circuit!

[Emorales]

Yes, you need a battery shop. My friend in LA was often melting a post in his EV, and the local shop would simply cast a new one on. With a short circuit, it's hard to tell if any other internal damage occurred. I'd be inclined to replace the 1 battery.

Checked and all batteries are showing 6.23v including the pictured one. The thing is that in that one theres no voltage on post. Thinking of getting lead melting it and refinishing the missing part. If not then buy a new one

Is it posible to replace or repair terminal post? And Happy Fathers day to all the fathers

+1. That experience helped me figure out that dangerous jobs improve the gene pool. But, just like driving over a cliff, it's a hell of a ride while it lasts.

Look at what the cat dragged in and coughed up. Welcome back.

Yep the young dumb and full of come ones don't live long.

Generally, oil field workers are some of the sharpest and toughest folks I've ever worked with. I leaned a lot from them.

A pretty common practice in the industrial field for Electricians is to remove all jewelry before going into the field to work. This is especially true for wedding rings.

FWIW, same goes for most anyone who works in fab./welding and machine shops, but for reasons usually/mostly unrelated to electricity.

Also, I used to root around in the oil patch some. Didn't take me long to notice a correlation between bits/pieces of finger loss and age of production workers (I noticed that because of how often they seemed to want to show me their middle digit). Anecdotally, the digit loss among those folks seemed only loosely correlated with the situational awareness of the personnel.

Guy I worked with at TRW, lost his ring finger to his motorcycle battery. It welded itself to battery and frame, and cooked his finger off - screaming all the while.
Battery had enough juice to weld, but not to vaporize.

Ditto and good advice and may not be as expensive as you think. Example to start take a close look at the hardware for all battery terminations. Chances are a simple insulated adjustable wrench (aka C recent which is a brand), insulated Slip Joint Pliers and screw drivers. Screw drives are easy to insulate your shelf with Heat Shrink Tubing. If you want to buy good quality tools for electrical work most every spark uses Klein Tools. Batteries are dangerous so give them respect. Enough energy just a slip of a wrench is enough to vaporize the wrench handle, and ladies and gentle get rid of the rings, bracelets and necklaces.

I have seen a wedding ring blown right of a finger. The poor SOB lost his finger when said and done from severe burns down to the bone. Never bled a drop of blood. His wrench slipped of the hot polarity on a -48 vdc power plant and went in tie framework. At first it was kind of funny at first. Sam was a Hill Billy with a heavy accent. We heard the pop and seen the flash. Sam never yelled or screamed. He just said; "dang where did my ring go"? and was looking on the for it. We found it in bits and pieces of gold BB's. The tough old bird went right back to work until I forced him to stop and took him to the hospital. While I was drivng him to the Hospital, he said;m "will lookey here what I found the rest of it" as he dug it out of his finger wife a knife. He pried it out of the bone. The tough SOB went to the bar after the hospital and made it to work the next day minus a finger. I still stay in contact with him.

Holly ****!!!!! ?
Guess what Im buying right now

Might also want to consider investing in a few insulated tools. I have just one - an insulated 3/8" ratchet - and it's saved me at least once from a fumble.

Ok so just had my first and hopefully last accidental short.

Its a (8) 6v batteries in series for 48v 235a/h. The inverter is a 2000w aims inverter charger. And 50A mppt

If the system is grounded you need just one on the volt Positive polarity. If it is a Floating system you will need a second one on the Negative polarity

50 Amp fuse to Inverter and contoller.

A1. How are the batteries configure? 12, 24, or 48?

A2. Refer to the owners manual. Without knowing battery voltage and Inverter wattage I cannot answer.

A3. I prefer Boxers.

Guess I learned the hard and costly way but thankfully all my limbs are intact. Ok so first thing I'm doing is buying the 2151 fuse block you suggested.
1. Should I fuse only the positive terminal, both and on all eight batteries or just first one(wired in series)
2. Batts are trojan 235amp@6v what fuse size you recommend for line that goes to inverter? And fuse size for line that comes from 60Amppt is a 60amp fuse ok?
3. Any advice on underwear
