280Comparación de baterías Ah LiFePo4: CATL contra. Eva contra. LISHEN vs. REPETIR

» Cómo elegir los terminales de la batería de iones de litio, the 280ah lifepo4 battery has become the mainstream of the energy storage market because of its high capacity and high cycle life. Lithium ion battery manufacturers have also launched 280ah capacity lifepo4 battery cells. Today we’ll compare a few common 280ah batteries.

1.Catlus

CATL is one of the top 10 lithium-ion battery manufacturers in China and one of Tesla’s suppliers, with a high reputation and unquestionable strength. His battery prices are naturally at a higher level. sin embargo, due to the global new energy market boom, there are especially many large electric vehicle and energy storage companies cooperating with CATL, resulting in a tight supply from CATL, and companies usually have to sign orders for a long time before they can get the batteries. CATL batteries of A grade are generally produced to supply directly to large car companies, etc.. It is difficult to get A-grade CATL batteries in the market for small scale or retail, most of them are B-grade or used batteries.

The following is the specific data of CATL 3.2v 280ah lifepo4 battery cell:

2.VÍSPERA

The most popular 280ah lifepo4 battery cell sold on the market is the LF280 from EVE. EVE is also one of the top 10 lithium-ion battery manufacturers in China. Their 280ah battery cell is also the main product of the manufacturer and was widely praised by customers once it was launched. Después, the manufacturer upgraded the product, making the cycle life of the battery cell from 3500times to 6000times. And set the 280ah battery according to the use of different versions of models. The specific differences between the different models can be found at: ¿Cuál es la diferencia entre EVE LF280 y LF280K?? The manufacturer has since launched a larger capacity 304ah cell, with an actual capacity of around 320ah, which is also selling very well. About this battery can be found at 304Ah battery cell.

The following is the specific data of EVE LF280K 3.2v 280ah lifepo4 battery cell:

If you need to purchase this product, please be sure to note whether you are purchasing an A-grade battery. A-grade cells are shipped with a finished product shipment report and a detailed battery data sheet. The battery data sheet records detailed data on each battery. Each battery will have a QR code on it, which is equivalent to the battery’s ID card, and the QR code corresponds to the battery data sheet one by one so that you know exactly what information is available about each battery. The finished product shipment report contains information such as Material S/N, order No. and Inspection date, which also corresponds to the information on the outer packaging of the battery.

EVE is now also putting the letter B on the QR code of recently shipped B grade batteries in order to distinguish between A grade and B grade batteries.As shown in the picture:

If there is no mark on the QR code, then there is a 50% chance that it is an A grade product, as there are some recycled and used A grade products on the market. These are usually products that have been used and are about to be phased out, with a much reduced number of cycle life. Much lower in price than A-grade batteries. To prevent safety hazards, we recommend that you pay attention to the above when purchasing. Choose A-grade batteries with finished product shipment report and battery data sheet.

 

3.LISHEN

LISHEN is a joint-stock high-tech enterprise with independent intellectual property core technology, specializing in the technological development, production and operation of lithium-ion batteries and power batteries. LISHEN does not currently have a 280ah cell, but he does have one close to this capacity: 3.2v 272ah lifepo4 battery cell. This battery cell is also currently selling well in the market. Because this cell has less capacity than the 280ah, the price per cell will also be slightly lower than the first two.

For more detailed data, please check PDF: REPT 280ah lifepo4 battery specification.

As we can see from the above data, the size and weight of these cells do not differ much, so if you do not have particularly strict requirements in this area, you can choose a suitable cell according to other aspects. In terms of capacity, LISHEN has a lower capacity than the other 3 models, so customers who need a slightly lower capacity than 280ah can choose this model. Looking at cycle life, the LISHEN cell has a cycle life of over 3500 times under standard conditions, while the other 3 models have over 6000 veces.

While focusing on the quality of the battery, we can choose the cells we need based on these data. If you have a need in this area or other questions you can also contact us, we will certainly provide you with a good price and good service to customize your battery solution.

P.S.: Faced with the massive demand for high-capacity batteries, CALB is also likely to launch lifepo4 batteries of around 280ah.
