FAQ
What is the lead time for mass production?
Standard battery prototypes typically take 15–20 days, while non-standard or highly customized batteries may require 25–45 days.Generally, mass production takes approximately 25–30 days after receiving the initial payment and final sample approval. The exact lead time may vary depending on project specifics.
Do you provide battery chargers?
Yes. We offer chargers specifically designed for lithium batteries. If you also require a charger, please contact our sales team for details.
What certifications do your battery products have?
We provide customized lithium battery solutions compliant with certifications and test reports such as CCC, UL, CE, RoHS, BIS, KC, IEC 62133, MSDS, and UN38.3, based on your market and application requirements.
Do you have batteries in stock?
All our lithium batteries are custom-designed. Each project differs in structure, voltage, capacity, and BMS requirements, so we do not offer off-the-shelf inventory.
What parameters are required to customize a lithium battery?
Typical requirements include dimensions, voltage range, operating current, peak current, runtime expectations, operating temperature, and connector/interface type.
How long does prototype development take?
Standard battery prototypes typically take 15–20 days, while non-standard or highly customized batteries may require 25–45 days.
