4S batteries for FPV drones

4S batteries are lithium-polymer (LiPo) batteries consisting of 4 cells connected in series, providing a voltage of 14.8V (standard) or 15.2V (HV versions). This configuration makes them an optimal power source for most modern FPV drones and quadcopters.

Advantages of 4S batteries for quadcopters

• Optimal balance of power and weight — 4S batteries provide sufficient power for dynamic flights without unnecessarily weighing down the structure
• Versatility of application — suitable for both racing and freestyle copters of medium size
• Availability of components — most modern motors and ESCs are optimized to work with 4S voltage
• High discharge current ratings — modern 4S batteries have impressive ratings up to 160C/320C

How to choose a 4S battery for an FPV drone

When choosing a 4S battery for a quadcopter, pay attention to the following characteristics:

1. Battery capacity

Our catalog features models with various capacities:

• 650-850 mAh — for light and compact drones up to 3 inches
• 1100-1300 mAh — universal option for 5-inch quadcopters
• 1500-1850 mAh — for longer flights and heavier configurations

2. Discharge current (C-rating)

The higher the C rating, the more power the battery can deliver during peak moments. For active FPV piloting, batteries with ratings from 120C and above are recommended.

3. Connector type

Depending on the drone size, different connectors are used:

• XT30 — for small drones with batteries up to 850 mAh
• XT60 — standard connector for medium and large quadcopters

4. HV or standard voltage

Batteries marked as HV (15.2V) have a higher maximum charging voltage, providing additional power at the start.
