Orange 7.4V 3300mAh 25C 2S Lithium Polymer Battery Pack

The Orange 7.4V 3300mAh 25C 2S Lithium Polymer Battery Pack is a high-performance rechargeable LiPo battery specifically engineered for RC aircraft, quadcopters, drones, and portable robotics applications requiring sustained high-current discharge. Professional hobbyists, drone pilots, and robotics engineers rely on this battery for its reliable power delivery and consistent performance across extended flight or operation sessions. This battery solves the critical challenge of providing lightweight, high energy density power with rapid discharge capabilities while maintaining voltage stability under demanding load conditions.

Product Overview

This Lithium Polymer battery operates on the principle of electrochemical energy storage using lithium-ion chemistry within a polymer electrolyte matrix, delivering superior power-to-weight ratio compared to traditional NiMH or lead-acid alternatives. The 2S configuration indicates two cells connected in series, producing a nominal voltage of 7.4V with a fully charged voltage of 8.4V per cell. The 3300mAh capacity provides approximately 24.42Wh of energy storage, while the 25C discharge rating ensures the battery can safely deliver 82.5A of continuous current, making it ideal for high-performance applications requiring instant power response and sustained acceleration.

The Orange brand LiPo batteries are manufactured with hardened polymer casing and internal protection circuitry to prevent over-discharge, over-charge, and short-circuit conditions. The 2S2P or equivalent cell configuration ensures balanced voltage distribution across cells, extending overall battery lifespan and maintaining consistent performance throughout the discharge cycle. Advanced manufacturing processes result in low internal resistance, typically below 15 milliohms, enabling efficient power transfer with minimal heat generation and voltage sag during peak current draws.

• Fast Charging Capability: Compatible with standard 2S LiPo chargers, supports 1C to 3C charging rates for quick turnaround between flights or operations

Applications and Use Cases

• Racing Quadcopters and FPV Drones: The 25C discharge rate provides the sustained high current required for aggressive maneuvers, rapid altitude changes, and competitive FPV racing where instantaneous power response is critical
• RC Aircraft and Helicopters: Delivers consistent voltage and power output for extended flight sessions, supporting both fixed-wing aircraft requiring sustained cruise power and rotary-wing platforms demanding rapid throttle response
• Robotics and Mobile Platforms: Ideal for autonomous ground robots, robotic arms, and mobile manipulators requiring high-current motor control and sustained operation without voltage sag affecting precision
• Portable Power Tools and Equipment: Suitable for cordless power drills, impact drivers, and portable electronic testing equipment where compact size and high discharge capability are essential
• Emergency Backup Power Systems: Provides rapid energy delivery for uninterruptible power supplies and emergency lighting systems requiring quick response to power interruptions

How to Use

Before initial use, inspect the battery for physical damage, swelling, or leakage. Connect the battery to a compatible 2S LiPo charger using the balance connector and main XT60 or JST connector. Charge at 1C rate (3.3A) for standard charging or up to 3C rate (9.9A) for rapid charging if your charger supports it. Monitor charging progress and ensure the charger terminates automatically at 8.4V per cell (16.8V total). Never exceed recommended charge voltage or charge rate, as this causes cell degradation and potential safety hazards.

During operation, monitor voltage under load using a battery monitor or telemetry system to prevent over-discharge below 3.0V per cell (6.0V total). Most applications automatically cut power at this threshold to protect battery integrity. After use, allow the battery to cool for 15-20 minutes before charging. Store the battery in a cool, dry location at approximately 50 percent state of charge (7.6V nominal) for extended storage periods. Use a fireproof LiPo battery bag during charging and storage to contain potential thermal events. Perform monthly maintenance charging if stored for extended periods to maintain cell health and prevent deep discharge degradation.

Frequently Asked Questions

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

The 25C rating indicates the maximum continuous discharge rate relative to battery capacity. For a 3300mAh battery, 25C equals 82.5A of continuous current (3.3Ah × 25 = 82.5A). This rating ensures the battery can safely deliver this current without excessive heat generation or voltage collapse. Higher C-ratings enable faster acceleration, quicker response to throttle inputs, and sustained high-power operations. The 50C burst rating allows temporary overload conditions for peak performance maneuvers.

How long will this battery last on a single charge?

Flight or operation time depends on average current draw, which varies by application. For a quadcopter drawing 20A average current, expect approximately 10 minutes of flight time (3300mAh ÷ 20A = 0.165 hours). RC aircraft with lower power requirements may achieve 20-30 minutes. Racing drones with sustained high-current draw may achieve only 5-8 minutes. Always monitor voltage during operation and land when reaching 3.0V per cell to preserve battery lifespan.

Can I use this battery with a standard charger?

Yes, this battery is compatible with any LiPo charger supporting 2S battery configuration. Ensure your charger has XT60 or JST connector compatibility matching your battery. Use the balance connector for accurate cell voltage monitoring during charging. Avoid using chargers without balance charging capability, as unequal cell charging reduces battery lifespan and increases safety risks. Always verify charger specifications before connecting.

What is the proper storage method for long-term use?

Store the battery at approximately 50 percent state of charge (7.6V nominal voltage) in a cool, dry location away from direct sunlight. Use a fireproof LiPo battery bag for safety. Avoid storing fully charged or fully discharged batteries for extended periods. Check voltage monthly and perform maintenance charging if voltage drops below 7.4V to prevent deep discharge degradation. Store at temperatures between 15-25 degrees Celsius for optimal longevity.
