Hello everybody,
first of all i am really impressed of this forum. I found tons of useful information.
Please correct me if i am using the wrong wording or in the wrong section of this forum. I tried to use the search function for this topic but i was not successful to find all information.
I want to build battery pack for my home energy storage application. But not sure about the long term life time of the cheap LiFePo4 batteries from EVE, Calt etc.
With a couple of suppliers from China i had telephone conversations and e-mail exchanges. I got a lot of different data sheets for same cells, wrong answers etc. .
Now i selected two suppliers but now sure how to make the decision. I have quotations from Xuba with good price (i believe) and a quotation from CALB directly that is cheaper than to buy in Europe and higher than Xuba.
From the short time view i should buy from XUBA. But what about the long term quality?!?!?
From CALB i will get a report with serial number for each cell. Is this a sing of good quality?!?!?
It would be great if some one of you could share your "long term experience" with their batteries.
Thank you
Regards from Germany
Peter
