5 Pcs RC Drone Replacement Battery, 3.7V 1800mAh Li Ion Battery for E88 E88PRO LsE525 E525 PRO

Battery Overview

The product set consists of five replacement batteries designed for use in the E88, E88PRO, LsE525, and E525 PRO remote‑controlled drones. Each unit delivers a nominal voltage of 3.7 V and a capacity rating of 1800 mAh, typical for lithium‑ion cells used in small electric aircraft. The batteries are supplied in a single package that contains five identical units.

Technical Characteristics

• Voltage: 3.7 V
• Capacity: 1800 mAh
• Cell type: Lithium‑ion (Li‑ion)
• Quantity per pack: 5 units
• Compatible models: E88, E88PRO, LsE525, E525 PRO

Design and Construction

Each battery is constructed with standard lithium‑ion chemistry, which provides a stable discharge curve and a high energy density relative to the cell volume. The 3.7‑V rating aligns with the nominal voltage required by the listed drone models. The capacity of 1800 mAh indicates the amount of charge the cell can store under ideal conditions. Because all five units share the same specifications, they can be swapped easily between drones or used in a backup configuration to extend operation time.

Application and Installation

These batteries are intended to replace the original power cells in the specified drone models. Replacing the batteries can help maintain flight performance when the original cells reach the end of their useful life or when additional power is needed for longer sessions. The replacement process typically involves disconnecting the old battery from the drone’s power system, inserting the new cell, and ensuring a secure connection. The 3.7‑V rating matches the drone’s power requirements, minimizing the risk of under‑ or over‑voltage conditions.

Handling and Safety Precautions

Lithium‑ion batteries require careful handling. The cells should be stored in a cool, dry environment and kept away from metal objects that could short‑circuit the terminals. When charging, use an appropriate charger that matches the battery’s voltage and capacity. Avoid exposing the batteries to extreme temperatures or physical impact. If a cell appears swollen or damaged, discontinue use immediately and replace it with a new unit from the same package.

Maintenance and Care

To keep the batteries functioning optimally, follow routine maintenance steps. Prior to use, allow the cells to reach room temperature after storage. Charge only to the specified voltage limits recommended for 3.7‑V Li‑ion cells. When not in use, store the batteries in a partially charged state (typically around 50 % of capacity) to preserve their longevity. Periodically inspect the battery terminals for corrosion or debris that could interfere with contact. Replacing any worn or damaged component with a new unit from the pack ensures continued reliable operation.

Storage Guidelines

For long‑term storage, keep the batteries in a sealed container to protect them from humidity. Store the pack in a location where the temperature remains between 15 °C and 25 °C (59 °F and 77 °F). Avoid prolonged exposure to direct sunlight or heat sources. If the batteries will remain unused for several months, charge them to about 50 % of their capacity, then re‑check and recharge to the same level if necessary.

Compatibility Notes

These batteries are specifically listed for use with the E88, E88PRO, LsE525, and E525 PRO drone models. They are not guaranteed to be compatible with other drone systems that require a different voltage or capacity profile. Use the batteries only in the indicated models to avoid potential power supply issues.

Environmental Considerations

Lithium‑ion batteries should be disposed of or recycled according to local regulations. Do not dispose of the cells in standard trash or incinerate them. Recycle through a certified battery recycling program to protect the environment from hazardous materials contained within the battery components.

Warranty and Support

The product package does not include explicit warranty details. For inquiries about product support or technical questions related to the batteries, contact the manufacturer or seller through the official communication channels. Any issues related to the compatibility or performance of the batteries with the listed drone models should be addressed through the appropriate support pathway.

Summary

This set of five 3.7‑V, 1800 mAh lithium‑ion batteries provides a straightforward replacement solution for the E88, E88PRO, LsE525, and E525 PRO drones. The batteries match the voltage and capacity specifications required by these models, enabling a seamless swap when the original cells are depleted or when additional power is desired. By adhering to proper handling, charging, and storage guidelines, users can maintain the reliability and longevity of these replacement units.
