Frequently Asked Questions

Q1 Can I customize my battery pack with specific features like Bluetooth, LED screens, or anti-vibration design?
Yes, absolutely. Let us know your requirements and our engineering team will provide a customized solution matching your applications, including marine, RV, or vehicle setups.
Q2 Can I get a lower price as a wholesaler, and how do you compare with cheaper alternatives?
We provide competitive wholesale pricing based on local market demands. While cheaper battery packs exist, they often use low-quality materials. We emphasize cycle life, warranty safety, anti-vibration structures, and communication interfaces. We also offer cylindrical cell solutions to meet different budget limits.
Q3 Is the 5-year warranty applicable to all situations and battery uses?
Battery cycle life is influenced by quality, temperature, and charge/discharge rates. For energy storage usage under room temperature (25°C), with 1C discharge and 0.5C charge, the battery pack cycle life can exceed 4,000 cycles, and is supported by a 5-year warranty.
Q4 Are these battery packs compatible with standard solar inverters?
Yes, our battery packs are compatible with most major inverter brands on the market, including SMA, Victron Energy, Deye, Goodwe, Growatt, Sermatec, and others.
Q5 What are the standard delivery times and shipping conditions?
For stocked products, delivery takes 3-7 days. For standard international shipping to the USA, Canada, Australia, and most European countries, we provide tax-included door-to-door services with delivery in roughly 40-55 days. Local shipments from our overseas warehouses arrive in 3-7 days with no tax fees.
Q6 How many battery cells do I need to build a system?
For a 48V system configuration, you will need 16pcs of 3.2V cells. For a 24V system, you will need 8pcs, and for a 12V system, you will need 4pcs.
