Q: How can I quickly find the battery I need?
A: You can search by different product lines or by application scenarios.
Q: Do you only sell batteries?
A: Besides batteries, we also provide BMS, battery enclosures, chargers, solar panels, and other related products.
Q: What is your delivery time?
A: Standard products are produced within 15-20 days and shipped immediately via sea or air. Customized products are produced within 30-35 days. Sea shipping usually takes 28-35 days.
Q: What are your advantages?
A: An extensive product line, fully traceable production processes, an average warranty of over 10 years, stable cell resources from CATL, BYD, Gotion, and EVE, and support for production process visualization.
Q: What payment terms do you support?
A: For orders below $10,000 USD, we accept 100% prepayment via T/T. For larger orders, we require a 50% prepayment. Once production is complete, we provide videos and images or conduct live video inspections, and the balance is paid before shipping.
Q: How does your warranty work?
A: Different product lines have different warranties. Electric motorcycle and high-rate power batteries generally have a 3-year warranty, 12V/24V energy storage battery packs come with a 5-7 year warranty, 48V home energy storage packs offer a 10-15 year warranty, and commercial energy storage packs generally have a 15-20 year warranty.
Q: What cell brands do you use?
A: We use cells from leading domestic brands like CATL, BYD, EVE, and Gotion. If you have a specific cell brand in mind, we can accommodate your request.
Q: What BMS brands do you use?
A: We have partner suppliers that provide custom Justlithium BMS for our standardized products. Our regular partners include Daly, Xiaoxiang, and JKBMS.
Q: Can I become your exclusive local distributor?
A: Of course! Initially, we usually offer a standard distributor agreement rather than an exclusive one. After 1-2 years of trial operations, we adjust our strategy based on market feedback, giving you the opportunity to become an exclusive distributor after just one year.
Q: How can I request a warranty?
A: If you encounter a problem, please contact us via email at admin@justlithiumbattery.com to request a warranty. Describe the issue you’re facing, and we’ll reply within 12 hours and assign a dedicated customer service representative to assist you. Further responses will usually come within minutes for quick communication.
Q: How does your warranty system work?
A: Once the issue is clearly understood, the product QR code is used to verify the purchase date. A dedicated engineer will then guide you through the solution. For irreparable products (not due to human damage), a free replacement of the same type will be provided.
Q: How do custom products receive a warranty?
A: Typically, the warranty period is determined through rigorous testing. However, custom products are designed and assembled to client specifications, making it challenging to conduct comprehensive short-term testing. In most cases, we provide a 5-10 year warranty, depending on the specific application scenario, which will be clarified during communication.
Q: Do your products have certificates?
A: Yes, to meet customs and various national requirements, our standard products are certified with CE, MSDS, and UN38.3. Our cells generally have RoHS, UL1973, and IEC62619 certifications, with digital certificates available.
