EVE LF304 3.2V 304Ah LiFePO4 Prismatic Battery Cell – Grade A

EVE LF304: The New Standard for DIY Energy Storage

The EVE LF304 (3.2V 304Ah) is the next-generation LiFePO4 prismatic cell, designed to supersede the legendary LF280K. By optimizing the internal chemistry and structure, EVE has managed to pack 8.5% more capacity into virtually the same dimensions, making it the ultimate choice for space-efficient energy storage.

Why Choose EVE LF304 Grade A Cells?

Higher Capacity, Same Footprint: Upgrade your system density. A 16S (48V) pack using LF304 cells delivers 15.5 kWh of energy, compared to 14.3 kWh with standard 280Ah cells.
Verified Grade A Quality: DLCPO supplies only Grade A cells directly from EVE’s factory. Every cell features an intact, scannable QR code that verifies its authenticity and production date. No B-grade or recycled cells here.
Long Cycle Life: Rated for ≥3,500 cycles at standard conditions (and capable of 4000+ with proper compression), these cells are built to last over 10 years in daily solar storage applications.

❓ Q:Is this better than LF280K?

💡 A:

Yes, it provides roughly 8.5% more capacity within the exact same dimensions, giving you higher energy density.

❓ Q:Do I need a BMS?

💡 A:

Yes, absolutely. These are raw battery cells. You must use a Battery Management System (BMS) to protect against over-charge, over-discharge, and temperature extremes.

❓ Q:Are the studs welded?

💡 A:

Yes, we supply these cells with Laser Welded M6 Studs. This is much stronger and safer than screw-in terminals, allowing for higher torque and better conductivity.

Warnings & Cautions

⏱️ Charging Alert: Stop charging the cells if the process isn’t completed within the specified time limit.

🛑 Usage Hazard: Stop using the battery immediately if it becomes abnormally hot, emits an odor, discolors, deforms, or shows any other abnormal conditions during use, charging, or storage.

🔥 Fire & Leakage Protocol: Keep away from fire or heat sources if leakage or foul odors are detected. If electrolyte leaks onto skin or clothes, wash immediately with fresh water. If it gets into your eyes, do not rub them. Rinse thoroughly with clean water and seek medical attention immediately.

🗜️ Assembly Notice: EVE cells require proper physical compression (approx. 300kgf) to achieve maximum cycle life. Always use busbars with a flexible expansion arch to accommodate cell swelling.
