EVE LF280K 3.2V 280Ah LiFePO4 Prismatic Battery Cell – 6000 Cycles

High-grade EVE LF280K 3.2V 280Ah LiFePO4 prismatic battery cell with laser-welded terminals for solar energy storage systems.

EVE LF280K (L173F280A): The Solar Storage Standard

The EVE 280Ah (Model: L173F280A, widely known as LF280K) is currently the most popular prismatic Lithium Iron Phosphate (LiFePO4) cell in the global market. Unlike the older LF280 model (3500 cycles), the LF280K is optimized for stationary energy storage, delivering an impressive cycle life of over 6,000 cycles.

Why is LF280K the Best Seller?

Extreme Longevity: Designed for daily deep cycling, this cell can last for 15+ years in a solar storage system (charged at 0.5C/25°C), offering the best ROI (Return on Investment).
High Consistency: EVE’s automated manufacturing ensures that capacity, voltage, and internal resistance (≤0.25mΩ) are incredibly consistent, reducing the burden on your BMS.
Standard VDA Size: Dimensions of 173.7x72x207.5mm make it compatible with almost all standard DIY battery cases and fixtures.

DLCPO’s “Grade A” Promise

Authenticity: We supply genuine Grade A cells directly from EVE production lines. No “B-grade” or swollen cells.
QR Code Verified: Every cell comes with an intact laser-etched QR code. You can scan it to verify the production date and model (L173F280A).
Value-Added Service: We offer Laser Welding Service for M6 studs. If you don’t have a spot welder, this makes assembly as simple as tightening a nut.

❓ Q:❓Q: What is the difference between L173F280A and LF280K?

💡 A:

A: They are the same product. “L173F280A” is the specific product code printed on the cell/datasheet, while “LF280K” is the marketing model name for the 6000-cycle version.

❓ Q:❓Q: Do these come with busbars?

💡 A:

A: Yes, DLCPO includes high-quality busbars and nuts with every purchase. Please specify if you need flexible laminated busbars (recommended for compression) or rigid ones.

❓ Q:❓Q: Can I ship these to Brazil?

💡 A:

A: Absolutely. We specialize in DDP shipping to Brazil, handling all customs clearance and taxes so you receive the batteries hassle-free.

Warnings & Cautions

Stop charging cells if charging isn’t completed within the specified time.

Stop using cells if the battery becomes abnormally hot, develops an odor, becomes discolored, deformed, or develops any other abnormal conditions during use, charge, discharge, or storage.

Keep away from fire or hot heat sources immediately when a leakage or foul odors are detected. If liquid leaks onto your skin or cloths, wash it out with plenty of fresh water immediately if liquid leaks from cells and gets into your eyes, don’t rub your eyes. Wash your eyes out with plenty of clean water and seek medical attention immediately.

Important: LF280K cells require 300kgf compression to achieve the rated 6000 cycles. We recommend using flexible busbars to accommodate cell expansion.
