Frequently Asked Questions

What is the difference between LiFePO4 and VRLA batteries?

LiFePO4 (Lithium Iron Phosphate) batteries offer significantly longer cycle life (up to 6000 cycles), deeper depth of discharge (80-100%), higher efficiency, lighter weight, and lower maintenance compared to VRLA (Valve Regulated Lead Acid) batteries, which typically last only 300-500 cycles and should not be discharged below 50%.

Can CSSUN batteries be used in solar energy systems?

Yes, CSSUN LiFePO4 batteries are ideal for solar energy storage. They are deep-cycle capable, have high round-trip efficiency (>95%), and are compatible with most solar inverters and charge controllers. Models like the LPW Power Wall series are specifically designed for home solar applications.

Do you offer OEM/ODM services?

Yes, CSSUN provides comprehensive OEM and ODM services. We can customize battery voltage, capacity, casing, communication protocols (CAN, RS485, etc.), and branding to meet your specific requirements for integration into your systems or resale under your brand.

What certifications do CSSUN batteries have?

Our batteries comply with international standards including CE, RoHS, UN38.3, MSDS, and IEC. We maintain strict quality control throughout the manufacturing process to ensure safety, reliability, and performance consistency.
