01 / Cell technology

Built around the cell.

For projects specifying new EVE A-grade LiFePO4 cells, final cell model and configuration are confirmed against the production order.

3.2VEVEA-GRADE CELL

EVE A-GRADE OPTION

Cell quality is the starting point of the battery.

EYUN can build the battery platform around the required voltage, capacity, enclosure and BMS architecture. The exact cell model, quantity and electrical configuration should be confirmed for each project.
