Description
Details
Grade A-: Grade A but this batch has a larger variation in production date and capacity. They come sorted by capacity. Not for packs of 200 or larger!
Capacity: 280 Ah
Maximum discharge rate: 1C (280A)
Size: 72mm x 207.5mm x 172.5mm
This is a 3.2V Lifepo4 cell.
The cells have a lifespan (to 80% capacity) of 8000 cycles when using a pressure of 280-320kg and charge at 0.5C (0.05C termination current to 3.65V) 0.5C discharge (to 2.5V)
With busbars.
With (aftermarket) studs.
22.5cm high including studs, busbars and nuts mounted
Capacity report available
For this batch:
capacity: 303-315Ah
IR 0.150-0.16 mohm (@3.295V)
Thickness average: 71.34mm (70.97-72.96)
Capacity: 280 Ah

Having done this I learned my 8 cells had production dates around Nov 2023, capacities between 319 and 322Ah and IR at 3.295V of 0.150 and 0.154milliOhms. As calendar ageing is the predominant factor limiting cell lifespan (greater even than cycling), I am not delighted to receive one year old cells, but the price of these cells was around 20 euros per cell less than the dual terminal LF280k v3 which NKON sell, so I consider some imperfection to be priced into the deal and accept that.
The physical condition looks great, with flat sides to the cells and a resting voltage on delivery of 3.304V per cell. The single stud terminals provide a fairly small surface area for the busbar to contact. Not an issue in my setup but maybe a consideration if you want to use a 12V inverter which will push the limits of the discharge C rate. (Posted on 07-12-24) - everything ok Review by EUGEN

QR code said that cells are B grade and are producem in 02/2024. I didn't test capacity. (Posted on 06-12-24) - Good quality Review by Maksym

The voltage on the cells was within 3.246V...3.248V, IR 0.12...0.15 mOhm. Production date within one month 12/30/2023 (1 pc), 01/06/2024 (1 pc), 01/07/2024 (2 pcs), 01/09/2024 (1 pc), 01/13/2024 (2 pcs), 01/26/2024 (1 pc).
All cells have approximately the same correct geometry, the average thickness is 71.5 mm. A convexity of 0.5 mm is considered permissible. (Posted on 21-11-24) - Damaged cell Review by Pavlo

Constantly informed about the status of the order by email. Very convenient, quality service. Delivery took three months upon pre-order.
I fully recommend it! (Posted on 19-09-24) - Good quality Review by Robert

Cell tested at 309 Ah 1020.9 Wh, which is great for a 280Ah cell. (Posted on 26-01-24)
