10 Frequently Asked Questions You Must Know Before Customizing UAV Battery Packs

1. What is the Minimum Order Quantity (MOQ) for Custom UAV Battery Packs?

Most manufacturers have a MOQ of 50 to 100 units. However, some offer sample customization to facilitate early testing.

2. What Voltages and Capacities Can Be Customized?

Common customizable specifications include:

• Voltage: 7.4V / 11.1V / 14.8V / 22.2V / 29.6V (2S~8S Li-ion batteries)
• Capacity: Ranges from 2000mAh to 30000mAh, designed based on flight duration requirements
• Cell Types: Soft pack / 18650 cylindrical / high-power lithium cells

How to Estimate the Required Battery Capacity?
Use the formula:
Required Capacity (mAh) = Total Power × Flight Time / Voltage × 1000
We recommend providing:

• Expected flight time
• Flight controller system power consumption
• Motor specifications
  We will help calculate precisely and recommend the proper cells.

3. What BMS Protection Features Are Available?

All custom battery packs can be equipped with a Battery Management System (BMS). Common protection functions include:

• Overcharge / Over-discharge / Short-circuit / Overcurrent protection
• Cell balancing
• Temperature monitoring
• Communication protocol support (SMBus, I2C, CAN)

4. Do the Batteries Support Fast Charging or Smart Communication?

Yes. Some battery cells support 3C~5C fast charging. We can also integrate smart BMS modules (e.g., I2C, UART) that connect seamlessly with flight control systems to provide real-time data such as battery level, voltage, and temperature.

5. Do the Batteries Meet International Transport and Export Certifications?

Our battery products support the following certifications:

• UN38.3 for air transport
• MSDS and IEC62133
• ROHS / CE (upon request)
  We also provide DG labels and complete export documentation.

6. What is the Battery Lifespan and Charge Cycle Count?

High-quality lithium cells typically support 300–800 charge-discharge cycles. The actual lifespan depends on usage scenarios, current rate, and temperature control. Under proper conditions, custom batteries can operate for 2–3 years.

7. What Is the Customization Lead Time?

Typical delivery timeline:

• Solution confirmation: 1–3 days
• Sample production: 5–7 days
• Mass production: 10–15 days
  If a special structure or mold is needed, the timeline may be extended.

8. What Structural Options Are Supported? Are They Waterproof or Shockproof?

We offer structural customization based on application environments, including:

• ABS or PC+Glass fiber enclosures
• Waterproof potting
• Shock-absorbing foam support
• IP65–IP67 protection levels
  Suitable for outdoor, cold, or high-humidity environments.

9. How Can I Start the Customization Process?

Simply provide the following:

• Target voltage and capacity
• Size constraints (if any)
• Application type and power consumption
• Any required certifications, waterproofing, communication features

You can submit your requirements via email or online form, and we will respond promptly.
