Yes, we guarantee that all CALB battery cells are 100% original, brand new, and Grade A directly from the factory, with verifiable testing reports.
Absolutely. We test and match all cells prior to packaging, ensuring they are closely aligned in voltage, capacity, and internal resistance (IR) for optimal pack building.
These cells feature a long cycle life of 2500+ cycles at 1C charge and discharge conditions under 25°C, before the capacity drops below 80% SOH.
Charging must only take place between 0°C and 55°C. Discharging operation can run safely between -30°C and 55°C, making them suitable for extreme environments.
Yes, our professional engineering team specializes in energy storage system structures and software. We support full OEM/ODM customization services to fit your technical design.
