Power Unlimited 2S 550mAh 7.4V 30C LiPo Receiver Battery
The Power Unlimited 2S 550mAh LiPo Receiver Battery offers a compact power option for compatible RC radio installations where space and weight matter. Equipped with a Deans-style T-plug main power connector, a universal JR receiver power lead, and a separate balance connector, this pack provides convenient connections for installation and balance charging.
🚀 Target Applications:
- Compact RC aircraft radio installations
- Compatible receiver systems using a separate battery
- Models requiring a small battery footprint
Select this pack only when its capacity, voltage, and connection ratings meet your system's requirements. Available operating time depends on the equipment and its actual power consumption.
⚠ Voltage & Current Compatibility:
- 8.4V Fully Charged: Before connecting directly, verify that the receiver, servos, switches, and all other powered accessories support a fully charged 2S LiPo battery.
- Regulated Systems: Equipment that does not support direct 2S LiPo power requires a compatible voltage regulator or external BEC set within its specified voltage range.
- Current Limits: The battery's discharge rating does not determine the current capacity of the receiver lead. Observe the ratings of all wiring, connectors, switches, and receiver power inputs.
Key Features
- Compact 550mAh Pack: A small battery option for compatible receiver installations.
- 2S LiPo Configuration: 7.4V nominal voltage with a 30C discharge rating.
- Two Power Leads: Deans-style T-plug main connection and universal JR receiver plug.
- Separate Balance Lead: For use with a compatible LiPo balance charger.
- Small Footprint: Measures approximately 2.28 × 1.18 × 0.47 in (58 × 30 × 12 mm).
- Low Weight: Weighs approximately 1.59 oz (45 g).
🔧 Installation Guidelines
- Check battery compartment dimensions and voltage compatibility before purchase.
- Follow the receiver manufacturer's instructions for selecting a power input and verifying polarity.
- Use a suitable regulator or power distribution system when required by your equipment.
- Secure the battery and wiring away from moving linkages and conductive parts. Insulate unused connectors.
- Monitor battery usage and recharge before the remaining capacity becomes insufficient for safe operation.
Both power leads connect to the same battery pack; they are not independent power supplies.
