Product Selection Guide
Choose the CB75 when the project requires a 3.2V 314Ah LiFePO4 cell, approximately 1kWh nominal energy per cell and long cycle performance for stationary energy storage. Confirm the required series-parallel configuration, system voltage, power demand, charge and discharge limits, thermal management, busbar design, enclosure dimensions, preload force and external BMS. The specification requires pack designs to apply a cell preload force within the approved range, with appropriate tolerance and mechanical support.
Product FAQs
What applications are suitable for the REPT CB75 314Ah cell?
Choose the CB75 when the project requires a 3.2V 314Ah LiFePO4 cell, approximately 1kWh nominal energy per cell and long cycle performance for stationary energy storage. Confirm the required series-parallel configuration, system voltage, power demand, charge and discharge limits, thermal management, busbar design, enclosure dimensions, preload force and external BMS. The specification requires pack designs to apply a cell preload force within the approved range, with appropriate tolerance and mechanical support.
How much energy does one CB75 314Ah cell store?
One cell has a nominal voltage of 3.2V and a nominal capacity of 314Ah, providing 1004.8Wh of nominal energy under the specified test conditions.
What is the cycle life of the REPT CB75 314Ah cell?
The specification lists ≥8,000 cycles until capacity decreases to 70% of the rated capacity. This result requires the specified 0.5P charge and discharge process, temperature and preload conditions.
Does the CB75 cell require an external BMS and mechanical preload?
Yes. The individual cell does not include an integrated BMS. A complete battery pack requires an external BMS, electrical protection, thermal monitoring and properly engineered mechanical preload and support.
