Can I get help with wiring of Battery

You and JR make it sound like battery fires are as common as farts.
Exact quotes:
Ebike battery fires are becoming commonplace.
Fairly commonplace to me.
Doubting the danger is fine, calling into question the danger for others is wrong. I didn't make a big deal or fear monger the danger, I only stated fires are becoming commonplace. The added emphasis came due to your minimization of the issue. Most battery fires never make the news, yet you can find hundreds of stories if you look for them.

I think most will never suffer a catastrophic battery failure or fire, I own 4 packs. When I see an obviously damaged pack and someone with zero knowledge of the wiring, I think it prudent to mention that fires are becoming commonplace. I didn't post stories until you cast doubt on the issue.

The best use of a forum is looking out for fellow members.
 
Not as narrow as yours.

I have stated that battery fires do happen. You and JR make it sound like battery fires are as common as farts. Lithium batteries would not exist if fires were as "commonplace" as you make them out to be.

I agree that bike batteries should be chosen, charged, and handled with care. I agree that the OP deserves the scrutiny he's been given.

I don't agree, if we're speaking English, that ebike battery fires are "commonplace" and I don't see the benefit in suggesting they are.

Sorry grumpy but all you have ard some internet anecdotes. Spend a decade in support and you’d learn something. That’s whatbi get for letting your posts be seen in my feed again. PLONK.
 
You never said the wires were cut by drilling out the lock. You sir ought to really step back...
How was the black wire severed? I asked for...

You never did...

"what I can see", so I pictured the area of concern to me. It's hard to tell from a photo and one angle... I have built serviced and fixed batteries...

Now that you've decided good helpful members giving good advice with half-assed information is taking on a new life...

Whatever if you built so many batteries and you saw the pictures I would think you would have some idea of what ask me

And again. You never provided accurate information or complete photos. I’m done here. Sloppy work by you, at best.

Sorry but I did say it was cut by accident please review the responses everything from dancing videos to battery fire debate,to the battery was dropped. I think most people would be frustrated with the responses and if you cant understand that Im sorry. It was a simple question of where do the black and red wires go
 
@Jarata, Can you post a photo of the back side of the original charger along with a photo of the bike's serial number? I think that will best help us to be able help you further. If not explain why. Thanks.
 
Funny, the curmudgeon calling me grumpy! I'm not grumpy, I'm very simply disagreeing with you. If you can't handle that without resorting to name calling then thanks for plonking me.

And JR. as far as pictures of battery fires on the internet being plentiful and easy to find, see what you can find on Google about Trump winning in 2020 then get back to me. Or car wrecks.

You can argue commonplace or becoming commonplace if you want. I guess lottery winners are commonplace too; they happen all the time, but it's not like your retirement is probably taken care of if you buy a lottery ticket.
Out of millions and millions of ebikes, yes, fires certainly happen. Maybe they happen every week, and if that's what you mean by commonplace, well, okay, but your chances of dealing with a battery fire are minuscule.

Again, I say use common sense. Buy quality batteries, charge them and handle them carefully.

You're just dishonest in debate. The pictures of bike fires are from the BBC, CBS, ABC and local newspapers and TV. Build your strawman with trump, heaters and Christmas lights. This is a waste of time debating conjecture and theories.
 
What do you think I'm dishonest about?

You point to Google about ebike fires. Why is you doing that any more valid than pointing to Google to show that Trump won in 2020, just for a silly example? How does knowing about a bike fire in the town where your brother live indicate that battery fires are becoming commonplace?

Is commonplace 1 in 100? 1 in 1000? A million? How many bike fires are there a year for every million batteries out there?

Probably as important, are these fires caused by carelessness or stupidity or are they totally random?

Hi,

I have a battery wiring question that I would really appreciate some help with.

From the picture below, are the load wires correct? (I thought 2, 12v batteries setup in parallel should have one load wire coming off one of the battery's negatives and the other load wire coming off the other battery's positives.)

Also, can anyone tell me what the small black wire is? Is that ground?

And lastly, when charging in parallel, do I hook up to the same spots where the loads are placed to charge both batteries at the same time?

The photo below is how the batteries were rigged when I bought them. But before I go and start breaking things, I would really appreciate your help.

Thanks so much!!!
No picture?!?!
If there is a BMS charging in parallel isn’t wise.
a new thread would be better…

Answer (one of many)
You point to Google about ebike fires.
Google is a browser.

Straw man
A straw man is a form of argument and an informal fallacy of having the impression of refuting an argument, whereas the real subject of the argument was not addressed or refuted, but instead replaced with a false one.
 
Concern over battery fires, assuming you aren't getting "creative" and are using an OEM battery supplied by a bike manf according to the manual, are about your level of paranoia.

Sure you can find some info on battery fires using Google. The same can be said about being hit by lightning, building collapses, and being attacked and eaten by an alligator or a shark.

Am I going to loose sleep over any of that? Hell no....
You do as you like.

I might be willing to offer an opinion, but I would want more complete info as well. Your pictures, showing little but the wire ends in question, offer darned little to go on. Maybe another set of pics, taken with a little more thought behind them, would help. Like where are the loose longer red and black wires coming from? The round thing the wires seem to be leading to, is that the outlet, where the bike plugs into the battery?
 
Answer (one of many)
So you can't answer that. Calling me dishonest, especially with a response like that, is pathetic..

Google is a browser.
I guess you mean it's a search engine. Maybe where battery fires are commonplace it's a browser, not in the rest of the English speaking world.

So your strawman argument is a strawman, right? My point, since you obviously missed it, is, of course you can find many references to anything you want on Google. Nothing you have provided indicates bike battery fires are commonplace (or becoming commonplace). "Commonplace" connotes relative frequency. "Relative" means compared to the whole. You are ignoring how many bike batteries don't explode or burst into flames. I'm totally guessing (find a real number to plug in here) but probably more than 99.97 percent of batteries don't burn. I don't think anyone thinks that something that happens 0.03% of the time is commonplace. 300 fires seems like a lot if that's all you consider, but not so much when compared to a million. Emphasis: I don't know what the real number is.

You've also ignored the question of which batteries burn? Is it mostly "bargain" batteries? Is there carelessness or stupidity involved most of the time? Or do all batteries burn at a rate that is becoming commonplace?

As requested...
Please show the entire battery.
