The battery builders club

No more coy lil quips like

?

I have de soldered the connection before, but even though I almost never need to i now use bullets of various sizes (usually mismatched to prevent accidental improper connection) to connect the bms to the battery. I don’t know if it will work here to clear the alarm either so definitely try the easy way first

I just explained the irony above for u:

You still think too unsafe to charge from 1v? You as well. Another safety patroller who was wrong. Or are the data sheets wrong?

Too unsafe?

Remember when u raged? Wow. You sid needed to be banned… for posterity

Did you ever hear back from the different manufacturers or about the different models to confirm that the unrelated spec sheet that did mention charging from +1v was applicable? If not then this is just another reckless recommendation based on cherry picking anecdotal data points while ignoring genuine questions and instead focusing on rage bate and pushing the victim narrative.

Doing something dangerous is perfectly acceptable, doing it for others is not. Telling others that it isn’t dangerous when you have no evidence or proof is borderline malicious.

You made a claim, people asked for evidence, the evidence was judged insufficient, now you’re acting like a whiny baby and spouting off instead of actually trying to find or get support for your opinion and claims.

I keep my finger on this thread to try and help others learn and understand how to make this inherently dangerous hobby a little more reliable and reduce the risks, while also trying to learn more about the process and effective methods of making and designing and maintaining battery packs in relation to esk8 and pevs in general… and half the time i look here it’s just you making some claim and not supporting it with adequate evidence and being butt hurt about it. Take it to derail ffs, or make a sincere separate topic to discuss it there

We already did this.

Many are power cells. No need to call the manu and they tell you in the data sheets. The data sheets ARE evidence. They obviously are what the manufacturer says you can do

  • trickle charging a cell from 1v is too dangerous to mention despite if stated acceptable in its data sheet?
  • It’s safe to trust the manufacturers’ statements in their data sheets?

Stop being a troll and start a wiki of cells and their minimal safe recovery voltages, you could be doing something productive with all this angst but here is just another example of you raging when you could be doing something helpful. Stop wasting your energy, you are obviously passionate about it - do something useful

The battery data sheets literally say you can do it. You think they’re lying?
@Pecos

You think if u call them they will say don’t trust their own data sheets?

“Raging”would be cursing and repeated insults and calls for banning. Let’s see if it happens again

So u think the data sheets aren’t proof?

Which ones? You never mention molicel and yet you recommend reviving them when they haven’t issued anything about letting cells get below 2.5v. Why do you think these cells have different ratings? You think maybe there is something different on the inside of the cell for each one? They aren’t a monolith - the specs and data sheets are different and the recommended voltage and amperage are all different but here you go, making assumptions. I never said not to trust the specs - i said repeatedly and politely to use the spec sheet of the cell you are working withto make recommendations about that same cell

All your blustering is redundant, ya i know some other cell has a different spec, why can’t you just read the title of the spec sheet? It says pretty specifically which cell and what manufacturer run it is appropriate for.

Let me guess: you will rebuttal with “trust me bro, they are the same so you can just do what i want”. “They published a spec for a different cell with different characteristics and different ratings and different chemistry and different internal constructions built to different tolerances that said it was ok so im gonna do that on this different cell once and its fine bro”

Well i definitely don’t trust your ability to read the spec sheets correctly when you can’t respond to what i actually said? Did you not read anything? Why not just yell at clouds and stop accidentally replying to me when you aren’t responding to me

My approach with everything in life:

Just because you can… doesn’t mean you should.

No I didn’t. I specifically said I’m not ur safety patrol and to research the appropriate cell data sheet

I posted some of them. MANY cell data sheets state u can. If u think im making it up or unable to read correctly u can look yourself and i literally cut n paste where it says so

Stop replying to me if you’re not gonna reply to me,

No mention of 1v or recommendation beyond minimum discharge of 2.5v. Quit projecting some attack nonsense on me and stop feeling attacked when someone else isn’t swayed by your argument. It’s in bad form. Go recover your 30t cells from 1v and be happy. Did you start a wiki? Did you make an honest attempt to qualify your recommendations and communicate the bounds of the advice without putting yourself on a cross? Did you respond to what i said.

You implied that the manufacturer did recommend something then said im not your safety person. Why even give this advice if you didn’t check to see if it even applied?!? This is not a good way to help people who are specifically asking about their situation. Like saying just - skill issue - without actually offering help. makes you look like a doofas and detracts from the entire point of the forum
