Hi. First post. I bought 4x304Ah cells from a seller on Australian Ebay for A$1079 (US$685). The red is the sale info:
Title - EVE 12V 304ah Lifepo4 Lithium iron Battery Solar cell grade A Phosphate
Text from the description:
Lifepo4 Lithium iron Battery Electric Vehicle 300AH 3.2V solar cells NEW 12V Phosphate cells.
Brand: EVE
5,000 cycle life
Size: 12V/12.8V 304AH .
Grade:A 100% new.
PC: 4 cells / 1 set 12V 304ah.
Each cell is 3.2V.
Delivered in a carton with no labelling stating that they were lithium. No paperwork with specs. Just the cells, bars & nuts.
According to the QR codes 3 cells have the same production date (4 months ago), 1 is a month earlier. All have exactly the same 972.8Wh Energy (is that suspicious, or is it worked out based on theoretical capacity?).
All are close to 3.29 volts. 2 cells have nice flat or slightly concave sides, but 2 have bulging as shown in the photo on both sides. They have octagonal terminal bases that I've never seen on any photo's of Eve cells.
Is the bulging within ok limits, or bad? Is it 'A-grade'? Are those octagonal terminals genuine Eve, or just some generic brand?
Anyone know of sites that have information backing this up?
