Orange 7.4V 850mAh 30C 2S Lithium Polymer Battery Pack

The Orange 7.4V 850mAh 30C 2S Lithium Polymer (LiPo) Battery Pack is a high-performance rechargeable battery designed for RC aircraft, quadcopters, drones, and portable electronics requiring sustained high discharge rates. Professional hobbyists, drone pilots, and RC enthusiasts rely on this battery pack to deliver consistent power output and extended flight times in demanding applications. This battery solves the critical challenge of powering lightweight aerial platforms and high-speed RC vehicles while maintaining optimal weight-to-energy ratios and preventing voltage sag under peak current demands.

Product Overview

The Orange 7.4V 850mAh 30C 2S LiPo battery operates on a 2-cell series configuration, delivering a nominal voltage of 7.4 volts with a fully charged voltage of 8.4 volts. The 850mAh capacity provides approximately 6.29 watt-hours of energy storage, while the 30C continuous discharge rating enables peak currents of 25.5 amperes, making it ideal for high-performance RC applications. The battery utilizes advanced lithium polymer chemistry with low internal resistance, ensuring minimal voltage drop during acceleration and sustained throttle operations. The distinctive orange heat-shrink casing provides visual identification and basic protection against short circuits and physical damage during transport and field operations.

This 2S configuration is engineered for applications where weight conservation is critical without compromising power delivery. The battery features balanced cell construction to ensure even charge distribution across both cells, extending overall lifespan and preventing premature cell degradation. Proper charging with a compatible 2S LiPo charger and adherence to storage guidelines at 3.85V per cell significantly extends the battery's operational life beyond 500 charge cycles. The compact form factor and flexible construction allow integration into tight spaces within RC airframes, quadcopter frames, and portable device enclosures.

How to Use

Before first use, inspect the battery for physical damage, swelling, or leaking. Connect the battery to a compatible 2S LiPo charger using the JST or XT60 connector and charge at 1C rate (0.85A) until the charger indicates full charge at 8.4V total or 4.2V per cell. Never exceed 1.5C charging rate as this may cause overheating and reduce battery lifespan. After each flight or use session, allow the battery to cool for 10-15 minutes before charging, and always balance-charge using the balance connector to ensure even cell voltage distribution.

For storage longer than two weeks, discharge the battery to storage voltage (3.85V per cell or 7.7V total) using a compatible charger with storage mode function. Store in a cool, dry location away from direct sunlight and extreme temperatures, ideally between 15-25 degrees Celsius. Never store a fully charged battery for extended periods as this accelerates capacity loss. Before each use, verify both cells read 3.7-3.85V using a battery checker to confirm safe operating condition. Immediately remove the battery from service if it swells, shows reduced capacity, fails to hold charge, or develops a burnt smell, as these indicate internal damage requiring safe disposal.

Frequently Asked Questions

What is the difference between 25C and 30C discharge rating?

The discharge rating indicates maximum continuous current capacity. A 30C rating on 850mAh means 25.5A maximum current (850mAh x 30 = 25,500mA), while 25C would limit to 21.25A. Higher C-ratings enable faster acceleration and more aggressive flight maneuvers without voltage sag, but generate more heat. The 30C rating makes this battery suitable for racing drones and high-performance RC aircraft where sustained high current is essential.

How long does this battery last per charge?

Flight time depends on your RC platform's weight and throttle usage. Typically, this 850mAh 2S battery provides 6-12 minutes of flight time on quadcopters, 8-15 minutes on RC aircraft, and 10-20 minutes on RC cars depending on load and driving style. Aggressive flying with continuous full throttle reduces flight time to the lower end, while smooth, controlled flying extends duration toward the upper range.

Can I use this battery with a 3S charger?

No, never attempt to charge a 2S battery with a 3S charger. Doing so will overcharge the battery to dangerous voltage levels, causing internal damage, fire risk, and potential injury. Always use a charger specifically configured for 2S LiPo batteries. Verify the charger display shows 2S mode and reads approximately 8.4V when fully charged before connecting your battery.

Why does my battery swell after use?

Swelling indicates gas buildup inside the battery cells due to overcharging, over-discharging below 3.0V per cell, physical damage, or internal short circuits. Swollen batteries are unsafe and should be removed from service immediately. Prevent swelling by charging at appropriate rates, never discharging below 3.0V per cell, storing at 3.85V per cell, and avoiding physical damage. If swelling occurs, safely dispose of the battery at an electronics recycling facility.
