Product Overview
EVE C40 40135 LiFePO4 Cell Overview
The EVE C40 IFR40135 is a large-format cylindrical LiFePO4 battery cell with a nominal capacity of 20Ah. Its 40135 cylindrical format provides a practical combination of capacity, durability and pack integration for electric mobility, industrial equipment and customized lithium battery systems.
According to the manufacturer specification, the C40 supports a maximum continuous charge current of 1C and a maximum pulse discharge current of 4C for 30 seconds under specified test conditions. Cycle performance reaches 4,000 cycles with ≥80% capacity retention under the specified 0.5C/0.5C test conditions.
For battery pack design or replacement projects, cell dimensions, operating voltage, discharge requirements, temperature conditions and series-parallel configuration should be evaluated according to the complete battery system requirements.
