Leaking Electrolyte from Bigbattery Powerblock

In my experience fast. It's just a chemical reaction. The more reactive the chemical to quicker it will happen. I'm not advising this but take some CLR and destroy your kitchen sinks finish. Won't take long.

Watch some restoration videos. Acid bath with/without a current and you can strip rust. Iron based hand warmers you buy at the store start almost instantly.

Soo, this battery had been mucked around with in several videos. Is there any chance it wasn't the manufacturer that damaged the cells? The cells have air in them. You live in the desert. Gas expansion. Is it really reasonable that every single cell is tested? Did anyone even know this could be a thing to test because it could cause and issue? It wouldn't be except this one configuration where the vent is side mounted. Who knew this end up was required here. Maybe this level of testing is required, I'm not the one to answer that. But I do like low prices and warranties for NONTOXIC items. EVERYTHING cost money. Testing COSTS money. How about the 11 in a million that fail, they just have you send it back for a brand spanking new one. I will hope mine fails 2 or 3 years into service. NEW ONE! BOOYA. And you don't have to pay hundreds extra for a bunch of tests that don't help anything.

I worked with rail industry for a time and tankers seem pretty simple right. One in thousands or millions of times something crazy/super normal happens and you break a giant piece of steel and it tosses that wheel.... up through a tanker. That tanker is full of oil. That detonates. We almost have to produce a nuclear bomb proof tanker to keep this from happening. Then you think... maybe this wouldn't be a problem if you just pumped oil in a pipe of keystone. We spend so much time and effort solving problems of things that are just bad solutions to a problem in the first place.

Some people on here have seemingly have had a pretty cushy and domesticated existence. They expect the lights to turn on and water to run. Try making sure all those systems run 24/7 365 for yourself. If you've ever worked in heavy industry or in an agricultural operation where you tend your machines all year long trying to assure they can run continuously for a few days/months to harvest. You quickly learn how everything breaks down. Getting up at 3AM to fix a water pump in a muddy cellar halfway across your farm covered in snow drifts, you start to appreciate everything has tolerances, and things break at the worst time.

Only too about one minute to research.



So much drama. Hopefully you can completely destroy a good company with hysteria. All this non-sense about PPE and the toxicity. Everything is toxic. Your 90+ water, yet if you drink a couple gallons in an hour your electrolyte levels will imbalance and your nervous system turns off. I need my nerves but some seem to operate without the brain part.

Petulant children want to have big ideas about how everything runs and operates. We should have an island to allow them all to run the utilities for a few months, and at the end let them see if they want to come back to civilization. Go ahead and set your own bed time and eat ice-cream for dinner. Let's see how it goes.


Side thought but its relevant
Renewables can only be utilized about 20/30ish% percent and it becomes exponentially harder to add more. Renewables are noisy destructive power. Most of the home generation doesn't get stored or used. It just gets burned up on the line in attenuation. Wind farms get into harmonics and literally blow up substations. The math to detect or design around this with thousands of rotating harmonic masses is Ph.D. level math. They build solar farms and forget to put in the transmission lines. Solar power is basically stealing money from your neighbor. So I don't get blasted, I'm building a solar system now for an rv type rig. It's engineering. Renewables are not for base load and grid backfeed. Without a 10 Trillion dollar smart grid on purchase not maintenance and upkeep. We can take your check for the year just to make that, but I'd like to keep my check. I like to eat food. Weird right.

Research LFTR Thorium. We would actually have the ability to remove carbon, not just fake say we did. The air would be a giant transport mechanism for carbon. You can manufacture clean, Co2 neutral petrol chemical any place on earth. There is now ample evidence that the the giant trees and plants and critters in the fossil record lived in a much much much higher C02 environment and thrived way better than today. I think we have all been sold a false bag of goods. But this is wrong think and no one is allowed to say it. The ice caps are freezing up now at unprecedented rates and we are entering a solar minimum and small ice age. Also more wrong think, despite the European Space Agency being on record saying CO2 isn't an issue, it's really the solar cycle. Think about it. A small tilt in our orientation causes seasons. A small wobble in our elliptical path around the sun causes hotter or colder years. Think of the sun like a component in your system design. What if the sun didn't output exactly at 100% capacity all the time with 0% fluctuation. The sun is sometimes a 60Watt bulb and other times 100Watt bulb.

rant much?
 
“I'm a little suspicious that some of the posts are ringers”

LOL Yep that very thought did artfully stumble into my observations after reading a few defensive objections on this big batt leaking cell mire of WTF. ??
 
@watchman1155 ..... Geez..... I thought after the first diatribe you'd be done .... but guess we aren't going to be that lucky.

So, you show up as a new member and start bashing anyone who is suspicious of BB ..... based on facts .... maybe you aren't aware of some of the history. Maybe look up the Big Battery is full of crap thread and bash a few people over there while your at it.

Maybe this is just semantics but 0.11% have had a leak, those numbers don't sound too bad. Less than 1%. That is acceptable numbers. That is death by shark bite then struck by lightening numbers. Recalling all batteries? There isn't a country wide service infrastructure for that. You'd break the company in shipping costs sending every one back to California. But I guess we are entitled to that. A recall for a car just costs parts and maintenance not shipping your car on a truck back to an assembly plant.

There wasn't a problem "on ALL the car" there was a few instances of an issue. You don't get a new car when there is a recall. But the upgrades aren't necessary. That was a token gesture to get a bunch of whiney customers to back off. Car's make things better yearly from lessons learned customer complaints minor wear and tear issues. Both parties have some skin in the game. You don't just get a new one because there has been upgrades.

The point about there should be no damage to the cells. There was not damage. Will even said it wasn't damaged and it's not obvious what the problem is. The vynal wrap around the batteries is barely function if not completely cosmetic. A little abrasion scuff that didn't even cut all the way through that super thin coating isn't a deal. There won't even be friction issues as tight as those things are locked in. Also, we don't know this wasn't from Will pokein around inside the battery. This isn't the first time he's crack the case.

Lol, you need to watch the BB video and find out why they wrap the batteriies. Do the reseach much before spouting crap?
Will caused the battery to leak by poking around? Here is my question? How much is BB is paying you? LOL!

Listen at 6:07 as to why they wrap the battery. COSMETIC? LOL!

Doesn't Will freeze his batteries and test them. Maybe the company knows he destructives test his batteries. Will ruined one. The company doesn't want to honor people destructively testing them and refused. There could be lot more to the story than is shown. It's called lies of omission. I find it interesting the videos were posted before BB was able to do anything about it. Sounds like extorsion.

So Will do the test to verify the claim is a bad thing? How do you think Will find out that the low temp charge shutoff did not work as BB claimed? He even has to prove to the BB engineers that they were wrong even proding the data to BB and BB admitted it and fix the problem after many have already been sold..
How do you verify if the product does what is claimed? Extorsion? LOL! So now Will is also the Extorsionist!

BigBattery 170Ah PowerBlock low temp cutoff does something for charging, but not sure at what temp or what happens with discharging

Test results video at end of post with description. Regarding Will Prowse's review of these nice batteries: Then Will commented on that video with this update: "Correction to this video: Unfortunately, I was correct about questioning the low temp charging protection on the powerblock...

Maybe you don't understand what Will does .... He gives his unbiased review of products. Some he buys and some are gifted to him.
Have you noticed that he posts what he finds and what he thinks about it no matter what. Renogy and others have been unhappy a few times also .... This is WHY Will is successful. If he looses that unbiased view, much of his success will go along with it.

Unlike Mr Green, who seems to try to say whatever is convenient, Will knows that his success lives and dies based on trust of his subscribers. He probably lost some significant coin removing that affiliate link from his website .... but he did it in order to maintain his integrity. Maybe Mr Green could learn something from Will regarding credibility.

I don't do business with people who lie to me ... and if I catch you in a lie once, it is going to take a LOT to ever regain my trust.

it’s been stated (quite sure by him) that he never opened the case that has the leaking battery. You’ll have to either read back through this thread or read the comments on the leaking battery video for reference to that.

That is true. Maybe they have a long history of being full of it. Can you reference. I'd like to know the history. I'm a bit confused why BB got such good reviews from Will in the first few videos prior to the leak, if there is this long history of them being shady. Something sees odd here. Now that there is an issue BB is an evil company?

However, even people you dislike can be right. I see a pretty big trend of fan boyism in this forum. And only a couple who actually deal in facts and logic not just conjecture and emotion. To those, thank you.

Despite, everything I saw from the video part 1 and 2 seems reasonable. Maybe bad design, seems like vents should be top mounted. Will seemed rather reasonable, maybe a little early to post a vid. You all are experts right? Why is everyone concerned with being poisoned. I thought LiPo4 was chosen because its a nice price point and materially safe for the masses.

I point out some clear logical fallacies and I get strawman arguments or straight up Ad Hominem attacks. People who are wrong usually quickly resort to logical fallacies and ridicule because they are unable to admit maybe they have been a little rash and their arguments won't hold up under scrutiny so they try to deflect.

Like, someone smarted off saying it's not hot in the desert right now. Yeah. Looks like Will is about to freeze to death. Maybe it will be even colder inside a sealed trailer in the direct sun. With electrical equipment not giving off extra heat. Guess that was just a real dumb question to ask. It defiantly hasn't been unseasonably warm were I live minus the one cold snap we just had. I guess we are all on board with the grand solar minimum then and the next mini ice-age.

Watch Will’s videos and read the forums. There have been various complaints from users in the forums, and will has had numerous bad experiences (video and forum documented) with their products, and even their support, up to and including this latest.

The forum does have a search engine.

Don't show up new and think you know where everyone is coming from. Most of your comments just seem completely uninformed.

I wonder if he, watchman1155, will retract about the EXTORSION. I hope Will is reading all of these.

@watchman1155 .... There's a couple of simple things on this thread. Did you see the pictures @SethRR posted? Did you see his description of the battery damage and symptoms he got from the battery?

I haven't seen any reason to doubt Seth's description of the battery or his communications with BB before he posted on this thread. During those communications, BB tried to say he somehow damaged the battery and it only looked like some sort of grease spot.

I have a big problem with Mr Green saying there was no functional problem with that battery and we have been waiting patiently for him to post the results of the battery inspection once they received it back.

In the mean time, we have had to endure the distractions from posts like yours.

I'm sorry I'm showing up in here new on your turf. I also apologize for not knowing to search for BB being a bad company, despite being new and just being told about that five minutes ago. I've since read a thread or two and don't see any substantive yet. I also apologize for watching all Will's videos on the company and other than the leak, the review put them in high regard. I guess he meant the exact opposite of the things he said. I don't get sarcasm.

apparently you have not watched all Will’s videos related to big battery. There is plenty of complaints, a history of questionable engineering decisions, and a general lack of taking responsibility rather than scape-goating.
 
watchman1155 said:
Is this a factor or your opinion. I mean a little plastic coating marred inside a sealed case on a component that is just cosmetic that voids the warranty if you open. I receive welded products that have occasional manufacturer scrap welded and powder coated that is sometimes even visible by reputable companies. I may be all washed up here but are we sure this is unacceptable?
Click to expand...
It's not just my opinion. The scratches on the PVC wrap are a result of a poor case design. So yes, that is not acceptable. If two or more cells come in contact with each other as the result of the PVC wrap wearing through and exposing the aluminum the cell is encased in, then that can cause problems. I don't know if Big Battery's battery case is isolated but if it isn't that could further cause problems. Have you looked at the Lishen spec sheet?
watchman1155 said:
So if the issue was fixed on all non-prototypes and the issue is resolved. I'm confused why everyone is all hating on BB then? Also, why no retraction or update video saying BB made good. enough time to instantly blast a company publicly but not enough time to send out a speedy update about the fixes? I havent looked at all the dates so maybe this is all the resolutions just transpired.
Click to expand...
Why don't you ask Seth if he thinks all of the issues were resolved....lol. I do not want Will to retract his video. Since Will posted that video Seth came along and reported his issue. He first commented about it on Wills video. Then I asked Will if he thought it would be wise to refer Seth to this thread. And here we are. A customer who it appears to have received a shoddy product from Big Battery, and Mr. Green has not yet posted an update.

I do not like that Will received a battery with cell(s) leaking and I am glad he is ok. If Will would have been the only one, considering it was a prototype, then it would not be as big of a deal. But now we have Seth who also received a battery with possibly leaking cell(s). And BTW, 11 leaking cells out of 10,000 is not acceptable and that's my opinion.

Personally I had never heard of a cell leaking until this thread was born. I know people on this forum have ordered thousands of cells, mainly EVE 280ah, and Lishen 272ah, and not a single person has reported a leak. Now you might conclude that's because people mount the cells upright. But not all have. I have concluded the cells are not always kept upright during shipping. There is a lot of handling going on between the time the order is placed with the supplier and the time the cells reach the user. Not a single person has reported a leak upon receiving their cells from the supplier.

So I will take a guess. Something was missed during Lishen's QC steps or possibly the cells were damaged in shipment. But if the 11 cells were damaged in shipment with no visible signs of damage that would be odd.

Regarding your theory considering heat in Nevada causing the cell to vent, I doubt that. I have seen people mistakenly do all kinds of damage to these cells and none leaked.
 
Since BB also found leaking cells in their stock (see the pictures in one of the post) in their own place in Chatsworth, CA.which is not in the hot desert. I also wonder if seth would get good response from BB if he did not post his issue on the video and on this forum since BB was trying to blame seth for the issue and then back track later as seth indicated. Also how can BB say it is white grease in seth pack without having the unit back in hand for inspection? Like I said, white grease is corrosive like that?
Also see BB video @6:07 time stamp as to why BB wrap the cells.

Glad you got all that off your chest .... but all that has very little to do with BB's response and spin on the leaking cells .... and trying to claim that @SethRR s pack was fully operational in spite of his report and the obvious damage ... and in the conversations with him, tried to blame him for the damage.

This is not the only BB problems we have seen on this forum ... in another one, they tried to claim a pack could be charged at -20C or something like that .... So, to me it is about whether or not we can trust this supplier.
Seems like they have had plenty of time to examine the pack from Seth that they got back ... and post some results. In the meantime, I'm a little suspicious that some of the posts are "ringers".

While I did join this board after the leaks, I'm not a "ringer". I've been watching Will for a while and built my DIY off grid solar array last year. Just looking to upgrade from 7.2kW of gel to something larger for extra storage. Beyond my arms length order (I didn't even join this board until after the items shipped and I didn't know about the leaks until after my order was placed), I have no relationship whatsoever with BB, Will, or anyone else on this board. If anyone needs further proof, I'd be willing to privately provide identification details to the verified admins.

Edit: to be crystal clear, I have not received anything of value from BB or any vendor without paying the public price. I did use Will's code to get the discount on my order but that is publicly available. No one has asked or paid me to post. No one gets to see my posts (other than myself) before I post them.

Here is my backyard five seconds ago. Battery is still here. Not sure why people think I sent it back yet, I've been busy installing an air conditioner on my shop.

Yeah it's sooooo hot out here ? and he posted a photo of me in shorts? Why don't people just Google search "las vegas weather" instead of creating conspiracy theories. I don't get it.

What in the world is this guy talking about? Has he not seen my videos bashing on their advertised capacity, failed low temp charging protection, or circuit breaker connections? This guy has no clue what he is talking about.

I have tested a lot of batteries over the last 9 years, and I have not had a leaking cell. I personally do not think it was a quality control issue. Those cells were bought from NEC as "new cells", but who knows what happened to them during that time. I dont know. Mr. green doesn't seem to know considering the shock he has had from the leaking cell. I personally have no clue why they are leaking, and I am still trying to figure it out.

Never did I draw a conclusion, and I took them off my recommended battery list. Considering how many times I have been pissed off at big battery in my past videos, some of these comments do not make sense. Have people not seen my videos?
