# 4S vs 6S Batteries for FPV Drones: A Comprehensive Comparison
Choosing between 4S and 6S LiPo batteries is a key decision for any FPV pilot. This guide breaks down the differences to help you choose.
## The Core Difference: Voltage
– **4S Battery**: Nominal voltage of 14.8V.
– **6S Battery**: Nominal voltage of 22.2V.
A 6S battery delivers more voltage, allowing motors to spin faster. However, this requires motors with a lower KV rating to avoid damage.
## Performance Comparison
| Feature | 4S (Higher KV Motors) | 6S (Lower KV Motors) |
|—|—|—|
| **Voltage Sag** | More noticeable under high throttle | Less sag, more consistent power |
| **Flight Time** | Generally shorter | Often longer due to efficiency |
| **Cost** | Less expensive | More expensive |
| **Best For** | Beginners, freestyle on a budget | Racing, high-performance freestyle |
