Frequently Asked Questions About LiPo Batteries
Are you a direct manufacturer or a trading company?
We are a direct lithium battery manufacturer based in Shenzhen. Our facility integrates R&D, automated production lines, and rigorous testing labs. Buying from us means factory-direct pricing, expert engineering support, and full control over your custom project.
How do you ensure battery safety and quality?
Safety is our top priority. We use only Grade A cells and implement 100% OCV (Open Circuit Voltage) testing and grading before assembly. Every battery is equipped with a high-quality PCM/BMS. Our laboratory conducts aging, vibration, and drop tests to ensure your batteries perform reliably without the risk of swelling or failure.
What is your typical lead time for samples and mass production?
We understand that time-to-market is critical. Engineering Samples: 7 - 10 working days. Mass Production: 25 - 30 days (depending on order volume and customization requirements).
Can you handle the shipping for "Dangerous Goods"?
Yes. Lithium batteries are classified as dangerous goods, and we are experts in global logistics. We use UN38.3 certified packaging and have long-standing partnerships with professional carriers for Sea, Air, and Express shipping. We ensure full compliance with international shipping regulations to your doorstep or port.
