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.
48.0 V system: Max. voltage 56.0 V, Max. discharge 43.3 V
24.0 V system: Max. voltage 28.0 V, Max. discharge 21.65 V
12.0 V system: Max. voltage 14.0 V, Max. discharge 10.82 V



The warranty period is 5 years from the date you receive.
We only replace new cell for free due to the failure of manufacturing.
Before the shipment, we will detect the cell voltage/resistance/appearance and other issues. we can only ensure that single cell is good before the shipment.
When arrival you can test the cells within 1 week, if you found problems please contact us for refund or replace. Any return behavior buyers need to be responsible for shipping fee.
Please read carefully all the description before taking orders, the battery is suitable for DIY lovers with experience, people who are not familiar with the safe use of lithium battery knowledge, please go to our shop to buy the finished product.
