What is the expected lifespan of these lithium battery units?
Our batteries are designed for high durability, typically offering over 3,000 to 6,000 cycles at 80% Depth of Discharge (DOD), depending on the specific cell chemistry and usage conditions.
Do you provide OEM/ODM customization for battery packs?
Yes, we provide full OEM and ODM services. We can customize voltage, capacity, dimensions, and communication protocols (like CANbus/RS485) to meet your specific application requirements.
What safety certifications do your products carry?
Our products undergo rigorous testing and carry international safety certifications, including UN38.3, MSDS, CE, and RoHS, ensuring safe transport and reliable operation.
How do you manage quality control during production?
We implement a strict multi-stage QC process: raw material inspection, cell matching, in-circuit testing for BMS, and a final full-capacity discharge test before packaging.
What is the typical lead time for bulk orders?
For standard models, the lead time is usually 15-25 days. Custom projects may take 30-45 days depending on the complexity and component availability.
How are the batteries packaged for international shipping?
