What are our company's advantages?

· In-house cell factory & R&D team: Total capacity of 6GWh (600 million Wh). Many competitors lack their own cell factories and battery R&D teams. Our cells offer ample, true-to-label capacity. · In-house battery pack (PACK) factory: We provide ODM/OEM turnkey solutions – from cells to finished battery packs – for manufacturers, integrators, and end-customers.

What is the company's Minimum Order Quantity (MOQ)?

Our MOQ starts from 1 unit . For first-time collaborations, we accommodate small trial orders to facilitate product performance testing. Larger quantities benefit from better unit pricing.

Do you provide samples? What are the lead times for samples and mass production?

Stock samples ship within 1 business day . Custom samples typically take 5-7 business days . Mass production lead times are generally 15-25 days , depending on order volume and customization requirements.

What are the payment terms and trade terms?

We accept T/T (Telegraphic Transfer) . Standard terms: 30% deposit + 70% balance paid before shipment . Before final payment, we provide actual product photos and packaging confirmation images.

What is the warranty period?

Standard warranty is 12 months . Extended warranties of 18-24 months are available for some custom batteries, subject to the specific product and cooperation agreement.

Do the batteries meet international certification standards?

Our products are certified to international standards including UN38.3, MSDS, CE, and RoHS , supporting global shipping and market access.

Batteries use lithium compounds as cathodes; different compounds have different properties. What are the main ones used in our company?

We primarily utilize: · Lithium Cobalt Oxide (LiCoO₂ / LCO): High energy density and well-rounded performance. · Nickel Manganese Cobalt Oxide (LiNiMnCoO₂ / NCM): More reactive; balancing energy density, safety, and cost by adjusting element ratios. · Lithium Iron Phosphate (LiFePO₄ / LFP): High safety, long cycle life, low cost – ideal for safety-critical and cost-sensitive applications.

What is battery cycle life? What is the standard for drone batteries?

Cycle life is a key measure of battery durability, indicating performance retention after repeated charge/discharge cycles. According to national standards, a battery should retain at least 70% of its initial capacity after 300 cycles .

What are the battery capacity and discharge rate (C-rating) requirements for different drone types?

Drone battery requirements vary significantly by application: · Large, stable-operation drones: Require 5–25C discharge rates, with capacities up to 70Ah. · FPV (First-Person View) drones: Require smaller capacities (5–10Ah) but very high discharge rates (60–100C). We typically use 3.7V or 3.85V high-performance cells for custom assemblies to meet diverse drone needs for high discharge rates and high energy density.
