EVE CELL LFP 3.2V 314Ah LASER WELDING

EVE CELL LFP 3.2V 314AH LASER WELDING

The EVE 3.2V 314Ah LiFePO4 cell is a high-capacity prismatic lithium iron phosphate cell intended for large battery systems where energy density, modular pack design and long-duration storage are more important than compact consumer-cell dimensions. At a nominal 3.2V and 314Ah, one cell represents approximately 1.0kWh of nominal stored energy before system-level losses and operating limits are considered. The ""laser welding"" designation in this SKU indicates that the supplied terminal format is intended for a welded interconnection process rather than assuming a conventional screw-terminal assembly.

Using nominal values, 3.2V x 314Ah gives about 1004.8Wh per cell. In a series battery pack, voltage increases with the number of cells while amp-hour capacity remains 314Ah unless additional parallel strings are used. For example, a 16S LFP pack built from identical 314Ah cells is commonly treated as a 51.2V nominal class, but the complete design must follow the cell manufacturer's voltage limits and the BMS settings selected for the project.

Large prismatic cells require more than electrical matching. Mechanical compression, busbar design, terminal process, thermal spacing and pack structure all influence long-term operation. Because this SKU is described as a laser-welding version, do not apply screw-terminal assumptions or hardware from a different terminal style. Welding parameters, busbar material and welding tooling should be qualified for the exact cell terminal supplied.

Use this cell only in a pack designed around 3.2V LiFePO4 chemistry and a BMS configured for the correct LFP series count. Before production, confirm cell QR/lot information, open-circuit voltage, internal resistance, physical dimensions, terminal layout and capacity matching. If cells from different batches are mixed, record their measured values and avoid combining obviously mismatched units in the same critical string.

Applications

3. UPS and long-duration backup systems

4. Industrial energy-storage modules

5. Large custom LiFePO4 battery packs

6. Battery R&D, prototyping and pack manufacturing

Installation Guide

Handle prismatic cells with insulated tools and protect the terminals from accidental short circuit. Use a rigid pack frame or compression method appropriate to the cell design, and maintain electrical insulation between cell cans, busbars and enclosure surfaces. For laser-welded interconnections, qualify the welding process before full production and inspect weld quality rather than relying only on visual appearance. Install an LFP-compatible BMS with appropriate voltage, current and temperature monitoring. During commissioning, check cell voltage spread and confirm that the pack does not contain a reversed or abnormally low cell.
