Capacity Specifications
Common Capacity Ratings
LIHV batteries are available in a wide range of capacities to suit different applications:
Micro Drones & Racing:
-300mAh – Ultra-lightweight racing
-450mAh – Lightweight FPV racing
-550mAh – Standard FPV racing
-650mAh – Extended racing
Standard Drones & RC:
-1000mAh – Compact drones
-1500mAh – Standard drones
-2000mAh – Extended flight
-2500mAh – Long endurance
Heavy-Lift & Industrial:
-3000mAh – Industrial operations
-4000mAh – Heavy payloads
-5000mAh – Extended operations
-6000mAh+ – Maximum capacity
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
كثافة الطاقة
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
Discharge Rate Specifications
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

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
