Top 3 Innovators & Manufacturers of Complete Battery Solution

What are our company’s advantages?

· In-house cell factory & R&D team: Total capacity of 6GWh (600 million Wh). Herewin has its own cell factory and battery R&D team. We develop high-performance cells, including 500Wh/kg anode-free lithium metal cell technology, with true-to-label capacity and stable performance.

· In-house battery PACK factory: We provide ODM/OEM turnkey solutions from battery cells to finished packs for manufacturers, integrators and end customers.

Heavy-lift drone batteries need high energy density, stable discharge performance, reliable BMS protection and proper voltage platform design. Herewin provides high-performance drone battery solutions for heavy-lift, VTOL, cargo and long-endurance UAV applications, with cell-level energy density up to 400Wh/kg. Battery voltage, capacity and C-rate can be selected based on payload, motor system, flight time target and operating environment.

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.

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.

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.

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.

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

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.

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.

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.
