FAQ

Please enter the title here

 1. What types of lithium batteries do you offer?
We provide a wide range of lithium batteries, including:  Lithium-ion (Li-ion) – High energy density, ideal for consumer electronics. Lithium Iron Phosphate (LiFePO4) – Long lifespan and enhanced safety, perfect for EVs and solar storage. Custom Battery Packs – Tailored solutions with BMS (Battery Management System) integration.
 
2. What is the typical lifespan of your batteries? 
Li-ion: 500–1,000 cycles (depending on usage and charging habits). LiFePO4: 2,000–5,000 cycles (longer lifespan with stable performance). Tip: Avoid deep discharges to extend battery life.
 
3. How should I store lithium batteries?
Store at 30%–50% charge in a cool, dry place (15°C–25°C / 59°F–77°F). Avoid extreme temperatures or humidity.
 
4. Are your batteries certified for safety? 
Yes! Our products comply with international standards like:  UN38.3 (transport safety) IEC 62133 (consumer electronics) UL/CE (regional certifications)
 
 5. Can I customize battery voltage/capacity? 
Absolutely! We offer custom battery packs with flexible configurations (voltage, capacity, size) to fit your project needs.  6. What's the lead time for orders? Standard products: 7–15 business days. Custom orders: 3–6 weeks (depending on complexity).
