Product Description

When an FPV drone demands high current, peak C-rate is only part of the equation. What matters is how consistently the battery delivers power throughout the flight. YIHANG develops and manufactures its own LiPo cells in-house, optimizing electrode and electrolyte formulations for high-rate discharge, low internal resistance, and stable power delivery. The result is an FPV Drone Battery engineered to maintain strong, responsive power throughout the discharge cycle, supporting demanding freestyle, cinematic, long-range, and high-load flight applications.

Production Line – From Cell to Pack

We manufacture our own cells. Most FPV Drone Battery brands don't — they source cells from suppliers and only handle final assembly. We keep the full process in-house: chemistry, electrode formulation, electrode coating, cell stacking, BMS assembly, and final pack integration.

Trial orders start at 5–10 units. Fly it first, then scale up when you're ready.

Customization & Sampling Timeline

Stage	Estimated Time	What You Need to Do
1. Requirement intake	1–2 days	Provide drone model, preferred voltage/C-rate, capacity target, and battery bay dimensions
2. Specification draft	3–5 days	Review and approve mechanical drawing, electrical interface, and BMS parameter sheet
3. Sample fabrication	10–15 days	We build 2–3 sample units per your spec
4. Sample validation	7–10 days	Perform flight tests; we share internal test report (capacity, IR, cycle data)
5. Bulk production	20–30 days	Place PO; we provide weekly production updates
6. Final QC & shipping	3–5 days	Each unit receives full electrical test + visual inspection; QC reports shared per batch

Key Advantages

• Instant Throttle Response (Zero Voltage Sag)

Engineered with ultra-low internal resistance to maintain a flat discharge voltage curve. Eliminates initial power hesitation during aggressive throttle punch-outs and high-current maneuvers.

• Sustained >10C Discharge & 120C Burst

In-house cell chemistry prevents motor power starvation during peak loads. Delivers continuous current for long-range cruising and instantaneous 120C burst output under heavy load conditions.

• Up to 350 Wh/kg Specific Energy Density

High energy-to-weight ratio reduces deadweight on 7-inch+ and cinematic airframes, improving agility, cornering precision, and total flight endurance without sacrificing discharge performance.

• Full Custom OEM/ODM Capabilities

Configurable from 2S to 12S voltage, 4000mAh to 18000mAh capacity, custom pack dimensions, specialized connectors, and custom logo branding. Prototype trial orders supported starting at 5 units.

Why Choose YIHANG for Your FPV Drone Batteries

In-House Cell Manufacturing & Chemical Customization

Unlike suppliers that re-package third-party cells, YIHANG manufactures LiPo cells in-house at our Dongguan facility. We directly control electrode slurry formulation, cell stacking, and electrolyte density, ensuring reliable 120C burst discharge and low internal resistance under heavy current loads.

Verified Flight Telemetry & Performance Data

Every technical specification—including 350 Wh/kg energy density, 120C burst power, and 1,000-cycle life—is validated through internal laboratory testing and field flight telemetry. Full test reports, discharge curves, and cell IR logs are available for technical evaluation.

Direct Engineering & Prototyping Support

Our 20-member engineering team provides direct technical support for custom pack geometry, connector selection, and BMS firmware customization. To accelerate airframe integration, we support trial prototype orders of 5 to 10 units with lead times of 10 to 15 working days.

FAQ

Q1: What's the actual C-rate in real flight, not on paper?

Our FPV Drone Battery is rated at >10C continuous and up to 120C burst — verified under real flight conditions, not just lab tests. Full-throttle punch-outs, rapid throttle changes, aggressive freestyle — the power holds.

Q2: Can you customize the size to fit my frame?

Yes. Send us your battery bay CAD or inner dimensions. We'll adjust cell stacking and casing to fit tight or irregular compartments — no extra charge for the first prototype.

Q3: How long does a custom order take?

Standard packs from our spec sheet: 15-20 working days. Full custom (new housing, BMS firmware changes): 25-35 working days. Trial orders ship in 10-15 days — we know you want to fly it ASAP.

Q4: Do your batteries support fast charging?

We recommend 1C for maximum cycle life. If you need faster turnaround in the field, 2C charging is supported with a moderate cycle life reduction (around 15-20%). We can optimize cell chemistry based on your priorities.
