Battery and Power Management
The battery is the lifeblood of any drone. Understanding LiPo chemistry, discharge characteristics, and power management is critical for safe and reliable flight.

C-Rating Explained
The C-rating tells you how fast you can safely discharge the battery:

Summary
- LiPo cells are 3.7V nominal, 4.2V full, 3.0V empty (never go below 3.3V!)
- C-rating determines max safe discharge current
- Capacity (mAh) determines energy storage and flight time
- Higher cell count (S) = more voltage = more power but more weight
- Always use low voltage alarms and balance chargers
- Battery weight is a major factor in thrust-to-weight ratio
