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
What is wrong with u. YOU need to read. Show me anywhere I said molicell can be revived from 1v
I’m not “implying” anything. I specifically said I’m not ur safety patrol and read ur data sheet. Ur argument is trash.
Does it state in many data sheets u can revive a cell from 1v?
Just answer the question. It’s a simple question.
(Also maybe the burden is on you to provide proof that you aren’t just trolling soon, because it’s getting old having to explain the same stuff over and over)
All of these in response to Common_good’s p42a build with low cell voltage and recovery. they are specifically in reference and trying the help and advice they were seeking into this strange hill to die on. Your reading comprehension here is lacking, and i can’t be relied on to refeed you the conversation you just had.
if in response to the bait of referencing your previous advice to recover cells at 1v or higher in contradiction to the data sheet while claiming it was conforming to the data sheets recommendations - and instead you just bounded your advice with “some cells can be recovered from 1v, but molicel doesn’t seem to have any reference to that on their sheet “ it would have been downright helpful. But instead here we are yelling at clouds again…
Be the change you want, want people to put a higher value on your opinion and advice : give advice that is complete and not a generalization that could be easily misinterpreted. You say people should look up the spec sheet and trust the manufacturer and you aren’t the safety patrol in an affect to not have to spend a bunch of effort addressing the specific question posed… then use all that saved effort and energy to argue without adding anything to the conversation? How does that make sense if you aren’t just using this platform to satisfy your need for rage bait?
It’s not some lofty elitism - it’s just trying to make something good and helpful and bs derail arguments that don’t actually push toward better understanding and application of the gathered information make it less valuable. You are so heated about cell recovery i wish you would put some of that energy into actual testing and data collection - if you did it could really help to make saving packs that get neglected safer and more understandable. But just using anecdotal experiences and not making actual proof with data that others can scrutinize doesn’t add anything and so gets a negative response from the people here who only want to offer reliable advice.
I’ll answer for ben even though this is just another empty unhelpful attempt to continue the argument without actually trying to find a resolution or bring more helpful information to the tabel and rely on others to refute your claims otherwise they be defaulted as facts:
Which cells hummieee? Please start a list of the ones you have found and make a resource or stop proclaiming persecution. This request is not in good faith and it falls on you to provide evidence.
Started a wiki but im on mobile so messed it up, start a list and help? I know you’re sitting on some you know specially are good to 1v
Ugh. Even if I write it repeatedly it doesn’t get read.
I specifically said I don’t know what cell the guy asking was using nor did I care. Go read it.
If someone else brings up charging from 1v again, out of nowhere, while trying to insult me, again, I’ll say again:
Read the data sheets and many cells, including power cells allow it. I’m not here to run through every cell’s data sheet. I’m here to pass this info on. It’s valuable in itself.
Many are salty because they didn’t know and raged that I should be banned and erased for saying so and it’s proven true with evidence.
Huh?
You’re thinking that it’s a good idea for me to spend at least hundreds of dollars and at least a year (too expensive to buy lots of testers) cycling several each of the popular cells to test 1V recovery tolerance?
Hmm…actually, I guess I can understand why you think something like that would be better for The Other Guy to do.
I would counter with this…start a fundraising effort to do this yourself and set it up to be exactly the testing you want. I’m happy to help with technical advice where I can.
Just a side note…this testing wouldn’t settle anything. You need to test hundreds of each cell and at different cutoffs and different temperatures and under different cycling conditions…thousands of cells and a couple of years for a major manufacturer to do. Otherwise we have no idea how close 1V might be to a problem threshold and what conditions are necessary for 1V to be set as a limit.
Without testing there’s NO evidence showing it’s dangerous. It increases dendrite growth sure but so does simply cycling cells anyway. Dendrite growth is not considered dangerous in itself.
Surely cell manufacturers did this testing already or they wouldn’t put that u can do it in the data sheets.
This is what people keep calling you out on man, and you didn’t read it over and over and keep coming back to the “i said do your own research “ bs. Then you say something like this in direct contradiction and want people to just go “ha ha hummiee is a dangerous troll sometimes” and let it stand?
this presumption is wrong and absolutely indefensible. By your same logic of grabbing data off one sheet to support an argument about a different cell, the warnings against letting a cell drop below the minimum volume on various other spec sheets should be applied here to counter this statement.
Also it is assuming an electrical system designed to operate within specific parameters will perform reliably when you have altered the parameters - this is counter to general good engineering and scientific principles. If the risks were low enough that would be fine and go have fun but the risks are fires in people’s homes. Even if the risks of an occurrence are small the magnitude of the worst case demands caution.
If i gave you a revolver with one bullet to play a little russian roulette with, how man chambers does it have to have before you feel comfortable pointing it at your own head? 6 is the accepted “you’re crazy “ number - what about 1/50? 1/100? We don’t have data that says how many chambers the cell recovery gun has when exceeding the parameters dude, and you want an answer don’t you? How much money is saved by taking this risk and where does this risk end or plateau? Stop trolling
No. I’ve said many many times now to look up the data on whatever cell you specifically are using and I’m not here to be safety patrol.
Do u need me to cut n paste it for a third time for u?!
When u find EVIDENCE that it’s not safe to recharge cells from 1v despite that specific cell data sheet saying it can… post it. Till then ur just talking and endless silly analogies.
Then stop giving advice about recovering cells from an under voltage / over discharge state. It’s irresponsible. Don’t pretend to be an expert and cosplay as helpful if you’re just here to troll
I’m saying simply trust the data sheets. Are you saying we can’t trust the data sheets?
It doesn’t take an expert to read what the manufacturer literally says you can do.
Stop trolling. If u find some evidence conflicting with what the manufacturer states is ok THEN post. Ur posting nothing
