Capacity Measurement

mAh (Milliamp-hours): Indicates how much current the battery can deliver over one hour.

•Example: 5000mAh battery can deliver 5000mA (5A) for 1 hour

•Or 1000mA (1A) for 5 hours

•Or 10000mA (10A) for 30 minutes

Wh (Watt-hours): Total energy stored in the battery.

•Formula: Wh = mAh × Voltage ÷ 1000

•Example: 5000mAh × 15.4V ÷ 1000 = 77Wh

能量密度

LIHV batteries typically achieve 160-200 Wh/kg energy density, compared to 150-180 Wh/kg for standard LiPo batteries.

Energy Density Calculation:

•Energy Density (Wh/kg) = Total Energy (Wh) ÷ Weight (kg)

•Example: 76Wh ÷ 0.27kg = 281 Wh/kg

放电率规格

C-Rating Explained

The C-rating indicates the maximum safe discharge rate of a battery.

C-Rating Formula:

•Maximum Current (A) = Capacity (mAh) × C-Rating ÷ 1000

•Example: 5000mAh × 100C ÷ 1000 = 500A maximum discharge

Common C-Ratings

C-Rating	应用	Typical Use
50C	Casual flying	Beginner drones, casual operations
75C	Standard performance	Commercial drones, general use
100C	High performance	Racing drones, aggressive flying
120C	极致性能	Competitive racing, maximum power
150C+	Ultra-high performance	Professional racing, specialized applications

Continuous vs. Burst Discharge

Continuous Discharge Rate: Maximum current the battery can safely deliver continuously.

•Typically 60-80% of burst rating

•Example: 100C burst, 60-80C continuous

Burst Discharge Rate: Maximum current for short periods (typically 10-30 seconds).

•Higher than continuous rating

•Used for acceleration and aggressive maneuvers

Discharge Rate Impact
