FAQ:
1: Where can I get a price?
A: We typically quote within 24 hours. For urgent requests, mark “urgent” or call our sales team.
2: Can I order a sample?
A: Yes. Contact us to confirm product model, shipping address and freight; we’ll arrange sample shipment.
3: What payment terms do you accept?
A: We accept Trade Assurance, T/T, PayPal and other secure payment methods.
4: Do you provide OEM/ODM and custom logo?
A: Yes. OEM/ODM available — color, enclosure, labels and packaging can be customized. MOQ discussed case by case.
5: What certifications do you have?
A: CE, KC, UN38.3, PSE, IEC and MSDS available; additional test reports can be provided on request.
6: What is the lead time for bulk orders?
A: Typical lead time is 15–20 days for standard cell orders; pack assembly and customized orders depend on quantity and specs.
7: How to charge and what is “full charge”?
A: Charge with recommended charger or MPPT input. Full charge is reached when charging current falls to ~0.02C after reaching recommended voltage.
8: What is “full discharge”?
A: Standard discharge at 0.2C until cutoff voltage per pack spec; BMS prevents harmful over-discharge.
9: Can this pack be used for home solar storage?
A: Yes — designed as a solar energy storage battery and pairs with common inverters and charge controllers.
10: How do you guarantee safety and quality?
A: Each cell and pack undergoes QC, electrical testing and aging; we provide test reports and support factory audits.
