LTO66160 40Ah 2.3V Lithium Titanate Battery Cell for High-Rate Industrial Applications
40Ah Lithium Titanate Battery Cell for High-Rate Power Applications
This 40Ah lithium titanate (LTO) battery cell is designed for battery systems that require high current capability, low internal impedance and frequent charge-discharge operation. With a nominal voltage of 2.3V and a cylindrical metal housing, it can be evaluated for industrial power systems, battery pack integration and other demanding electrical applications.
High-Rate Charge and Discharge Capability
The cell supports a maximum continuous charge current of 240A and a maximum continuous discharge current of 240A under the specified test temperature of 25°C ±5°C. Its specified pulse current reaches 400A for 10 seconds under the same temperature conditions. Actual current limits depend on operating temperature, cooling, system design and the manufacturer’s operating instructions.
Low AC Internal Impedance
The specified AC internal impedance is ≤1.0mΩ under the stated measurement conditions. Low impedance can help reduce resistive losses in suitable battery configurations. Actual system performance depends on connections, busbars, cell matching and pack design.
Wide Specified Operating Temperature Range
The specified operating temperature range is -40°C to +65°C. This range should not be interpreted as a guarantee that maximum current is available at every temperature. Charging and discharging require appropriate current limits and thermal management, particularly at low or high temperatures.
Designed for Battery Pack Integration
The cylindrical format supports evaluation by battery pack manufacturers, industrial equipment developers and system integrators. Before deployment, engineers should verify the required series-parallel configuration, voltage range, protection strategy, thermal design and application-specific safety requirements.
Important: The stated cycle-life figure is based on a specified test criterion. Actual service life depends on operating conditions, charge-discharge profiles, temperature and system design.
