Orange 3.7V 1800mAh 25C 1S Lithium Polymer Battery Pack

The Orange 3.7V 1800mAh 25C 1S Lithium Polymer Battery Pack is a high-performance single-cell LiPo battery designed for demanding RC applications, FPV drones, and portable electronics requiring sustained discharge rates. Professional hobbyists, drone pilots, and electronics engineers rely on this battery for its exceptional power delivery and reliability in compact form factors. This battery solves the critical challenge of maintaining consistent voltage output during high-current draw operations while delivering extended flight times and responsive performance in weight-sensitive applications.

Product Overview

This 1S Lithium Polymer battery operates on the principle of electrochemical energy storage using lithium-ion technology in a polymer electrolyte configuration. The 25C discharge rating indicates the battery can safely deliver 25 times its capacity in continuous current, meaning this 1800mAh pack supports sustained discharge rates of 45 amperes without thermal degradation or voltage sag. The single-cell configuration provides a nominal voltage of 3.7V, which is ideal for direct integration into low-voltage systems or as a foundation for multi-cell pack configurations. LiPo batteries offer superior energy density compared to NiMH alternatives, delivering more power in a lighter package, making them the industry standard for performance-critical applications.

The 25C rating ensures this battery excels in high-performance scenarios where consistent power delivery is essential. Unlike lower-rated batteries that experience voltage collapse under peak current demands, this pack maintains stable voltage curves even during aggressive acceleration or rapid throttle applications. The orange casing provides visual identification and protection against physical damage, while internal protection circuitry helps prevent over-discharge and short-circuit conditions. This model represents a balance between capacity, discharge capability, and physical dimensions, making it suitable for medium-sized FPV racing drones, RC quadcopters, and portable power applications requiring 30-45 minute operational windows.

How to Use

Before first use, inspect the battery for physical damage, swelling, or leakage. Connect the battery to a compatible LiPo charger with balance charging capability, using the JST or XT60 connector as appropriate for your equipment. Charge at 1-2C rate (1.8-3.6 amperes) for optimal cell health and longevity. Monitor charging progress and disconnect immediately upon completion to prevent overcharging. Always use a LiPo-specific charger with cell balancing functionality, never attempt to charge using standard NiMH chargers or wall adapters.

During operation, monitor battery voltage using an in-line voltage checker or receiver telemetry system. Land and disconnect the battery immediately when voltage reaches 3.0V per cell to prevent permanent capacity loss from deep discharge. After flights, allow the battery to cool for 15-20 minutes before charging. Store the battery at 3.85V per cell in a fireproof LiPo storage bag in a cool, dry location away from direct sunlight. Perform monthly maintenance charges if storing for extended periods. Always follow your charger manufacturer's instructions and local regulations regarding lithium battery handling and storage.

Frequently Asked Questions

What does the 25C rating mean and how does it affect performance?

The 25C rating indicates the battery can safely discharge at 25 times its capacity continuously. For this 1800mAh battery, this equals 45 amperes maximum sustained current. This high discharge rate minimizes voltage sag during aggressive throttle inputs, maintaining consistent motor performance and control responsiveness. Higher C ratings enable faster acceleration and better handling characteristics in racing applications, but also generate more heat during operation.

How long will this battery last on a single charge?

Flight time typically ranges from 30-45 minutes depending on aircraft weight, throttle profile, and motor efficiency. Heavier platforms with aggressive flying styles consume capacity faster, while lighter aircraft with conservative throttle inputs achieve extended flight times. Testing with your specific equipment is recommended to establish accurate expectations for your application.

Can I use this battery with my existing charger?

This battery requires a dedicated LiPo charger with balance charging capability. Standard NiMH chargers or universal chargers without LiPo mode will damage the battery or create fire hazards. Verify your charger supports 1S LiPo charging before connecting. Most modern hobby-grade chargers include LiPo profiles and balance charging connectors compatible with this battery.

How should I store this battery when not in use?

Store at 3.85V per cell in a fireproof LiPo storage bag in a cool, dry location away from direct sunlight and heat sources. Extreme temperatures accelerate degradation. If storing for more than two weeks, charge to storage voltage monthly to maintain cell health. Never store in fully charged or fully discharged states, as both conditions reduce cycle life.
