Drone Battery 3PCS 3.7V 1800mAh and 4Pcs Propeller Blades, Mini Propellers Accessories Drone Battery with Blades for E88 E88PRO E525 E99 E99PRO P1 K3 S1 RC UAV Battery Plug and Play

Drone Battery and Mini Propeller Set

This accessory package contains three individual lithium‑ion batteries, each rated at 3.7 V and 1800 mAh, along with four mini propeller blades. The batteries are designed to fit a variety of small remote‑control aircraft, providing a straightforward, plug‑and‑play power solution.

Battery Details

• Quantity: 3 batteries
• Voltage: 3.7 V
• Capacity: 1800 mAh

The 3.7 V rating is typical for single‑cell lithium‑ion packs used in lightweight drones and similar RC UAVs. The 1800 mAh capacity offers a balance between size, weight, and runtime for compact flight platforms. Because the batteries are supplied in a set, users can swap or replace individual cells as needed without removing the entire pack.

Propeller Blade Specifications

• Quantity: 4 blades
• Size: Miniature, suitable for small quadcopter frames

The blades are crafted to complement the batteries in the set, offering a cohesive package for new or existing drone builds. Their dimensions are compatible with a range of miniature rotor systems commonly found on small RC UAVs.

Compatibility Overview

The batteries and propeller blades are engineered to operate with the following models:

• E88
• E88PRO
• E525
• E99
• E99PRO
• P1
• K3
• S1

These models span several series of compact quadcopters and multi‑rotor drones. The set’s design ensures that users can connect the batteries directly to the power input of each listed device, simplifying the installation process.

Plug and Play Convenience

Each battery features a standardized connector that aligns with the common power terminals found on the compatible drone models. The propeller blades are pre‑spun to a standard pitch, eliminating the need for additional adjustments during assembly. The combination of batteries and blades in a single kit allows for quick setup and minimal handling.

Use Scenarios

Whether a hobbyist is upgrading an existing quadcopter or assembling a new build, the set offers a practical solution for small aircraft requiring 3.7 V power sources. The included propellers provide an immediate aerodynamic option, reducing the time spent sourcing separate components.

Installation Steps

1. Attach each battery to the designated power port on the drone.
2. Secure the propeller blades to the motor housings.
3. Verify that all connections are firmly seated.
4. Perform a quick pre‑flight check to ensure all systems are operational.

Following these steps ensures that the power and thrust components are correctly aligned, supporting reliable flight performance within the design limits of the listed drones.

Quality Considerations

The batteries are supplied with protective circuitry to mitigate over‑discharge and over‑charge scenarios common in single‑cell lithium‑ion units. The propeller blades are manufactured to match the aerodynamic profiles typical of miniature quadcopter designs, providing consistent lift and stability during flight.

Maintenance Tips

Regular inspection of the battery terminals for corrosion and the propeller blades for cracks or deformation helps maintain optimal performance. Replace any damaged component promptly to avoid potential flight interruptions.

Summary

This 3‑battery, 4‑blade set offers a complete, plug‑and‑play package for a variety of small RC UAVs. The batteries provide a 3.7 V, 1800 mAh power source, while the propellers are sized for miniature rotorcraft. Compatibility with the E88, E88PRO, E525, E99, E99PRO, P1, K3, and S1 models ensures a ready‑to‑fly solution for users of these popular drones.
