Product Information:
⚡️ EVE 356Ah LiFePO4 3.2V Grade A+ ⚡️
These Cells are Original LiFePO4 cells directly from EVE, with certificate, and the actual capacity of the cells are 356–370Ah (each cell is individually tested and signed by the inspector).
✔️ 356Ah capacity – Ideal for energy storage projects
✔️ Grade A quality – Automated production, tested with precise measuring equipment
✔️ 8000+ cycles – Long lifespan for sustainable energy supply
✔️ QR code engraved – Each cell individually marked
✔️ Balanced cells – Ready for immediate use and of the highest quality
To avoid contact resistance, the following points must be observed:
✔️ Thoroughly clean the battery terminals with ethanol or pure alcohol to remove oxide layers.
✔️ The terminals must not be touched with greasy fingers – they must be absolutely grease-free and clean.
✔️ Ideally, the contacts should be cleaned with a brass brush or fine sandpaper (grit 1000).
✔️ The contact surfaces of the cell connectors must also be carefully cleaned.
❌ The use of assembly greases, copper paste, or similar substances must be strictly avoided – they cause contact resistance, which can lead to heat generation and measurement errors during operation. As a result, the full capacity of the cells cannot be utilized.
🔧 Tighten the M6 screws with a torque of 6 Nm.
NOTE
We recommend a maximum discharge down to 2.70 V and a maximum charge of each cell up to 3.50 V.
