Top 3 Innovators & Manufacturers of Complete Battery Solutions

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.

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.
