There are some problems with the price. You will find that the price is a little too low by referring to the market price. Too cheap batteries are often a scam.

Why are swells allowed? The purpose of battery compression is to prevent swelling...

The purpose of battery compression is to keep the battery from expanding.

BYD batteries are fine, but blade batteries...seem to be used only on their EV models. How did the blade batteries on the market come about? ? Are you curious? Also, the overly cheap LiFePO4 batteries deserve your attention, which is most likely a scam.

Personally, I recommend DIY batteries, which are cheaper and have a higher degree of freedom. Another point is that because there are so many people in this forum who can help you, you won't get bogged down in the mud.

My personal suggestion is to use the included busbar to compress the battery first, and then choose a copper busbar to maximize the performance of the battery pack.

Mainly depends on your usage. It seems that what you need is a power station. In the case of long-term and frequent use, LiFePO4 batteries are the best choice. After all, the energy density is relatively high, which can fully meet the needs of energy storage. Of course, LiFePO4 batteries are...

Bulging, in fact, more people will write it as "Battery Swelling". Swelling means that there is too much gas inside the battery, which may even cause damage to the internal components. die, and will become more dangerous. However, whether the swell can be used also needs to be judged according...

Fundamentally, all prefabricated LiFePO4 batteries (OTS batteries) are the same, with LiFePO4 cells + BMS inside. Therefore, as long as the price is within the market price range, it is worth buying, but you may have to compare multiple energy storage battery brands to get the best choice. Also...

"Powerwall" means that what you need is actually a prefab battery (also known as an OTS battery)? That "battery core" doesn't seem to be in your consideration. But actually, a DIY battery might be better because it's fully customizable, it's cheaper, and there are plenty of experts on the forums...

One thing I'm curious about... Does a battery that actually leaks have a unique weird smell??? Because it was mentioned before that coolant also smells.

Maybe re-measurement of voltage/resistance/capacity is what you need to do now. As long as these parameters meet the standards, then the problem is not big. After all, from the picture, it does not seem to be a serious bulge. The problem can be solved by battery compression. It's the leak...

Correct. LiFePO4 battery safety is great, does not explode, and is very difficult to catch fire. More often the wire or device connected to the battery catches fire...so some insulation would be very welcome.

The battery swelling problem does not occur with normal Grade A batteries, but slight swelling can be solved by compressing the battery, and this will not affect the performance of the battery. All you need to do is measure the internal resistance, voltage, and capacity of each battery first, if...

I support selling it to people who need it more, like the bro above. This allows your battery to continue to function as a "battery" and be of more practical value. If it is sent to an electronics recycling center, it means battery recycling, which can only keep the raw materials of the battery...

For safety's sake, it's best not to use it, because it's impossible to tell if it's coolant or electrolyte, and the best way is to stay away from it. LiFePO4 battery leak is uncommon, but once it occurs, it is more dangerous.

It might be complicated. As you said, you're likely to receive low capacity, used, or even concrete, too cheap LiFePO4 batteries as a result that isn't worth the risk.

Not everyone has the time to DIY batteries. A simple example would be all kinds of electronics that might cost between $100-$200, but you need to pay $500-$600 to get them. The great thing about a turnkey product is that you just pay and you don't have to do anything. From another point of view...

The sun said, "I won't go to work today."

Let me guess, scammed by the battery supplier?

First, confirm your purpose and needs. Are you planning to use it off-grid long term? If it is used for a long time and there is a relatively large performance requirement, LiFePO4 batteries will be very good. If it is only intended for normal use, lead-acid batteries (such as GEL) are also very...

My advice is don't do it. Obviously, your Blue Carbons battery has a built-in BMS, even if your new battery will have the same voltage, the internal BMS may affect each other, resulting in the unstable performance of the new battery pack. Most cases of mixing batteries only apply to "battery...

Generally speaking, it does. But not all brands of LiFePO4 batteries have QR codes. In addition, laser etching is not necessarily brand new and authentic. Now many counterfeiters also have laser machines to assist in counterfeiting, so beware of fake batteries at all times.

Are you sure you want to buy it on eBay? For $150 you might get some concrete in exchange. Too cheap LiFePO4 batteries are not worth the risk, let alone it looks like an outright scam.

Keeping the voltages equal is the most important thing. A slight difference in capacity is acceptable for mixing batteries, and many people actually do.

The video is too long, but my estimate is: the energy density is higher, 111 orders but still does not exceed 180Wh/kg; the safety is also higher, but it is still not completely non-flammable; the cost performance is higher, but still not acceptable Classified as cheap. Has anyone finished the...

China's LiFePO4 battery level may already be at the top level. As for the price issue, I think it should be the issue of tariffs and shipping charges. I have seen many orders with hundreds or even thousands of shipping charges in the forum... So there seems to be a reason for these battery...

That's OK. In most cases of mixed batteries, it is only necessary to ensure that the voltages are equal (that is, in parallel), so it is good to expand the batteries. Also, I'm curious about one thing, why to 600Ah? Wouldn't it be better to raise the voltage a bit?

Whenever it comes to shipping, protection is necessary, albeit a little more expensive. However, inverters don't come cheap, and if they get damaged in transit, you can get really frustrated.

Just make it yourself. Boxes for LiFePO4 battery compression are easy to make, using wood or insulating boards and stud sets. These can be easily found in building materials stores. Very cheap.

Thanks for your sharing. But it is just preliminary research. With current technology, safety and energy density are always at odds, so just smile. I have an example. I don’t know if you have heard of aluminum-ion batteries. A few years ago, many people advocated the super performance of...

Because I don't think battery grading is meaningful, it's scary that there is no industry standard for battery grading, and each battery factory has its own grading standard. So I generally only believe in battery performance, battery grading is like 100% juice on a juice drink, I wouldn't...

My point is the same as yours, the so-called grading really doesn't make much sense, and performance is everything. As far as I know, both Tesla and BMW have experience communicating with EVE Energy...Although I don't know if they have successfully cooperated, compared with these super...

Sorry! I'm missing one premise: most DIY batteries. Some factories with few EV battery companies can still create their best batteries for you, like Winston. But now the most cutting-edge technology of LiFePO4 batteries exists in battery factories capable of manufacturing EV batteries. It is...

This seems to be a rumor, but it seems that you have a misunderstanding. For battery factories, EV batteries are their main business, and the batteries that are suitable for cars are classified as A, and those that are not suitable for cars are classified as B or below, which is a fact. And for...
