EVE Lithium LFP Cells List 3.2v

A list of cells manufactured by EVE in July 2024.
It details the capacity, energy density, estimated cycle life, weight, and Internal resistance of each cell.

Using this information you might be able to decide what cells suit your application best.
For example the LF50k cell is rated for 7000 cycles at 1C charge and discharge. But its energy density is very low. The main reason it gets such a good rating is because it can be actively cooled or heated in the right application, which can help tremendously with lifespan.
However you will also note that cycle life is now mostly spoken about at 0.5C or P. Meaning much of the information previously released has been further corrected over time.
All of these numbers are best case scenario, and usually at 25 degrees Celsius. So these numbers are basically unattainable in most cases.

Guide to Connecting Solar Panels in Series with Victron Charge Controllers

Guide to Connecting Solar Panels in Series with Victron Charge Controllers

Connecting solar panels in series with Victron MPPT (Maximum Power Point Tracking) charge controllers requires careful consideration of voltage limits and configuration. Hereโ€™s a step-by-step guide:

1. Understanding Series Connections

In a series connection, the positive terminal of one panel connects to the negative terminal of the next. This setup increases the total voltage while keeping the current constant. For instance, if each panel has a voltage of 40V and they are connected in series, the total voltage is the sum of each panel’s voltage.

2. Calculating System Voltage

To ensure compatibility with your Victron charge controller, calculate the total open circuit voltage (VOC) of your system:

[ Total VOC = VOC per panel x number of panels in series x times 1.1 ]

The factor of 1.1 accounts for temperature variations, which can increase the voltage. For example, three panels with a VOC of 40V each will have a total VOC of ( 40 x 3 x times 1.1 = 132V ).

3. Checking Controller Specifications

Ensure that the total VOC does not exceed the maximum input voltage of the Victron MPPT charge controller. Exceeding this limit can damage the controller. Victron MPPT controllers have different voltage ratings, so choose one that accommodates your array’s maximum VOC.

4. Choosing the Right Wire Gauge for Solar Installations

Selecting the appropriate wire gauge for a solar installation is crucial to ensure safety, efficiency, and minimal energy loss. The wire gauge determines the amount of current that can safely flow through the wire, which is critical in preventing overheating and voltage drop. Hereโ€™s a guide to choosing the right wire gauge based on common solar installation sizes:

Factors to Consider

  1. Current (Amperage): The amount of current the wire needs to carry.
  2. Distance: The length of the wire run between the solar panels and the charge controller or battery.
  3. Voltage Drop: The reduction in voltage that occurs as electric current moves through the wire. A lower gauge number means a thicker wire and less voltage drop.

Common Wire Gauges for Solar Installations

  • 18 AWG (~0.82 mmยฒ): 1 mmยฒ cable, suitable for low current applications, up to 5A.
  • 14 AWG (~2.08 mmยฒ): 2.5 mmยฒ cable, common for small systems, up to 15A.
  • 12 AWG (~3.31 mmยฒ): 4 mmยฒ cable, used in medium-sized installations, up to 20A.
  • 10 AWG (~5.26 mmยฒ): 6 mmยฒ cable, for larger systems, up to 30A.
  • 8 AWG (~8.37 mmยฒ): 10 mmยฒ cable, for high current requirements, up to 50A.
  • 6 AWG (~13.3 mmยฒ): 16 mmยฒ cable, used in high-current or long-distance setups, up to 65A.

6 mmยฒ cable, for larger systems, up to 30A, this is going to be most common wire size used in PV in Australia, as the MC4 Connectors are normally limited to 30A. This cable size is standard for medium to large residential and small commercial solar systems, ensuring safe and efficient energy transfer. It’s readily available from most electrical and solar supply stores in Australia.

Voltage Drop Consideration

For optimal performance, aim for a voltage drop of less than 3%. You can calculate the required wire gauge using the formula:

Voltage Drop = 1000 (2ร—Lengthร—Currentร—Resistance per unit length)โ€‹

Where:

Resistance per unit length is the resistance of the wire (in ohms per meter)

Length is the one-way distance of the wire run (in meters).

Current is the amount of electrical current flowing through the wire (in amperes).

Where length is the one-way distance in feet, current is in amperes, and resistance is the wire’s resistance per unit length (in ohms per 1000 feet). This formula helps ensure that the wire gauge chosen minimizes energy loss and maintains system efficiency.

Conclusion

Choosing the right wire gauge is a balance between current carrying capacity, voltage drop, and cost. Overestimating the required gauge can lead to unnecessary expenses, while underestimating can cause safety hazards and inefficiencies. Always consult with a qualified electrician or solar installer to ensure that your wire sizing meets local electrical codes and safety standards.

5. Grounding and Safety

Proper grounding of the solar panel array is crucial for safety and system longevity. Follow local regulations and manufacturer guidelines for grounding methods. Additionally, use overcurrent protection devices like fuses or breakers to protect your system components.

6. Monitoring and Maintenance

Regularly check connections and the performance of the system. Victron controllers often come with monitoring capabilities, allowing you to track system performance and make adjustments as needed.

For detailed specifications and guidance, always refer to the Victron MPPT charge controller manual and consult with a professional installer.

The Lifepo4 QR code B to A Grade problem

Q. What is a QR Code?
A. It’s a 3D barcode

Q. What is a Barcode?
A. A visual representation of data

Q. Can a barcode be scanned to verify authenticity of unique products?
A. NO! A QR code does NOT authenticate product genuineness because it can be easily copied or duplicated by anyone.

Put Simply, if I have some text or numbers, I can quickly and easily generate a QR code. It is static data. It does not connect to EVE or any other manufacturer.

Q. Why I keep writing these articles over and over?

Part 1

I am observing that most sellers in Australia (Melbourne, Sydney, Rockhampton, Perth, and Brisbane) sell B grade cells as A grade. They either don’t care, or they don’t know themselves. It’s really disappointing.

I have to defend our own business sometimes, yet those same people attacking me are under the impression that the other sellers are selling genuine products, but I KNOW they aren’t.

  • a) I know because I have seen their cells in person, and I have seen the packaging. I can see they are buying from QSO, Basen, Docan, or EEL by the boxes, the stickers, the busbars, and the QR CODE!
  • b) I have spoken to most of the sellers personally.
  • c) I have seen the evidence over and over again.

Part 2

I have always known what a barcode and therefore a QR code is. I have personally worked in stock control systems since I was a teenager and in IT for years. I sold and supported stock control systems. We work with barcodes all day, and we know what a keyboard wedge is. (I know that 99.8% of people do not.)

Part 3

I only recently realized that most (not all) people do not understand what they are or how they work.

I’ve watched multiple people scan the code, thinking they were connecting to an authenticity server or something. Recently, I actually watched a guy scan his “known fake” jacket, which had a QR code on it, and I finally realized that people just don’t understand this technology in general.

Let me say this in BOLD red text!

QR CODES DO NOT AND CAN NOT VERIFY AUTHENTICITY

QR Codes for DUMMIES

Below this paragraph I have given you a QR code generator. You can make it do whatever you want within a set number of characters. It can create any data, like

If I have a spreadsheet with genuine QR codes, I can then generate a QR Code. If someone gets a hold of a spreadsheet like this one, attached here. EVE uses a 24 character “string” of numbers and letters as their identifier.
1200px .xlsx icon.svg1
Click it to download the spreadsheet of real QR codes, from a real EVE spreadsheet

Use this tool in orange, to create your own EVE barcodes using the Spreadsheet.

In Depth detail of QR codes

The amount of text a QR code can hold depends on the version and error correction level. Hereโ€™s a general idea:

  • A standard QR code (Version 40, the largest version) can hold up to:
    • 7,089 numeric characters
    • 4,296 alphanumeric characters
    • 2,953 binary (8-bit) bytes

However, practical QR codes used in everyday situations usually hold much less data to ensure they are easily scannable.
For best results, itโ€™s advisable to keep the text short, typically under 300 characters, to maintain quick and reliable scanning.

Summary

EVE and others like them use QR codes for internal tracking while manufacturing battery cells. They are not there for the end user, to verify the authenticity.

QR Code created with a QR Generator by LiFePo4 Australia

THIS QR will have the string of data “https://lifepo4.com.au” You can scan this with a camera app, or a QR Code scanner and it will take you to this website, it won’t work with the LIFEPO4 QR Scanner, because that app has been modified to interpret batteries only.

If you have the spreadsheet with genuine QR codes, You can then generate a QR codes and upload them to the Laser Engraver, and every 5 seconds you can laser engrave a new QR code onto a B grade cell, making it appear as a genuine A grade product, that even matches the spreadsheet you are looking at.

Stop thinking Chinese people are not educated, the truth is that many Chinese, over 100 Million of them hold college degrees, they are smarter than you, almost certainly. And it only takes a few to tell the others what to do. Just like an engineer would do in Australia to his subordinates. As of recent data, approximately 18.3% of Chinese people hold higher education degrees.
That means, that there are more educated people in China, than the entire population of USA and Australia combined.
It also means that there are at least 10-20 educated Chinese people for every one of us.
Make your own judgement.

How to use a spreadsheet to generate and print new QR codes with a laser

If someone (think shady Chinese battery mafia figure) gets a hold of a spreadsheet like this one, attached here. They can then upload the data onto the Laser Machine, then one by one, they will write over the top of the Invalid or B Grade QR Code. Thus making a Battery cell with 280ah appear to be a 330Ah cell.

It is really simple, the entire process takes a few seconds at most per cell. I have seen a video of this being done, I did not have the ability to save that video, and I cannot seem to find it no matter how hard I Google and Baidu it. The videos are private for obvious reasons. But they do exist.

The Process of QR code Re-Lasering

Q How does QR replacement take place, and who is doing it?

A. In China, there are vast warehouses full of products that did not meet specifications for use in commercial or high voltage battery pack use. They are still batteries, and they work, but for how long I hear you ask?

“how long is a piece of string”

QR CODES DO NOT AND CAN NOT VERIFY AUTHENTICITY

Summary
A QR code is like a sticker. Anyone can print the same sticker and put it on anything, so it doesn’t prove the product is real. Only trusted sellers, like us, can guarantee the product’s genuineness.

Why a Lifepo4 QR Scanner app does NOT verify the Authenticity or Genuineness of Batteries

As we have discussed, a QR code is STATIC,
1. It does not connect to a database and return anything that can be used to know if the product is real or fake.

The Lifepo4 QR Scanner App, has a database, (think of it as a big spreadsheet. The database contains all the cell models, and some logical programming for the app to be able to decode all known QR codes. The user who created this app, did this to assist the community to try to know what product of battery cells, and where they were made and what capacity they were.
He has been able to gather enough data to make it work for the most popular manufacturers.

Once he has this image and others like it from the other manufacturers, he can very easily decode the important data, and that will return you a result on what that QR is supposed to be attached or printed on. (notice I said supposed)

Why Does all this even matter?

In a high voltage battery pack, it’s crucial that the batteries in series are matched and high quality because:

  1. Balanced Performance: Matched batteries ensure consistent performance, as each battery will charge and discharge at the same rate.
  2. Safety: High-quality batteries reduce the risk of failures, such as overheating, leaks, or explosions.
  3. Longevity: Using matched and high-quality batteries extends the overall lifespan of the pack by preventing weak batteries from causing the entire pack to degrade faster.
  4. Efficiency: Ensures that the battery pack operates at optimal efficiency, providing reliable power output without losses due to imbalance.

By ensuring batteries are matched and high-quality, you maintain the safety, efficiency, and durability of the high voltage pack.

But wait there is more!

If a single battery cell in a high voltage pack is faulty, it impacts the entire pack because:

  1. Chain Reaction: In a series configuration, the current flows through each cell in the chain. A faulty cell disrupts this flow, reducing the pack’s overall performance.
  2. Reduced Capacity: The faulty cell limits the pack’s capacity to the weakest cell, causing the whole pack to discharge faster and reducing its overall capacity.
  3. Safety Risks: A single faulty cell can overheat or fail, potentially causing damage to adjacent cells and posing safety hazards like fires or explosions.
  4. Increased Wear: The healthy cells are forced to compensate for the faulty one, leading to uneven wear and shortening the lifespan of the entire pack.

In summary, a single faulty cell can degrade the performance, capacity, and safety of the whole pack, highlighting the importance of ensuring all cells are high quality and well-matched.

Now the best way to explain this using math:

If you have 16 cells in series, all of which are 330Ah, though a single cell has only 150Ah of capacity, then the entire pack will lose 55% of its capacity.

In this example the single cell, limits the pack to a total of 16 x 150Ah. Making your pack only 7.6kWh, when it should be 16.8kWh.

In dollars in today’s market, this would mean,

A $5000 investment would lose $2750 in value.

Making your battery worth only $2250

Not only this but the cell will continue to cause problems, causing your power to cut off regularly, and remain out of balance, and it will strain every other component in your pack.
