Power Unlimited 2S 4000mAh 7.4V 30C LiPo Battery
The Power Unlimited 2S 4000mAh 7.4V 30C LiPo Battery provides high-capacity power for compatible radio systems and RC aircraft setups. Equipped with a Deans-style T-plug main power connector, a dedicated universal receiver plug (JR/servo style), and a 2S JST-XH balance connector, this pack offers flexible connection options for sport, scale, and F3A pattern airplanes.
🚀 Target Applications
- Dedicated receiver power systems for compatible sport and scale airplanes
- F3A precision pattern aircraft using a separate radio-system battery
- Gasoline or glow-powered models requiring on-board receiver and servo power
Choose your power connections and any required regulator to suit the voltage and current requirements of your equipment.
⚠ Voltage & Current Compatibility
- 8.4V Fully Charged: A fully charged 2S LiPo reaches 8.4V. Before connecting it directly, verify that the receiver, all connected servos, switches, and other powered accessories support this voltage.
- Regulated Power: Equipment that does not support direct 2S LiPo power requires a compatible voltage regulator or external BEC set within the equipment's specified voltage range.
- Receiver Lead Capacity: The battery's 30C rating does not determine the current capacity of the smaller receiver lead. Keep current within the ratings of the wiring, connectors, switch, and receiver. Higher-current systems may require a suitable power distribution unit.
Key Features
- 4000mAh Capacity: A high-capacity pack for compatible on-board power systems.
- 30C Discharge Rating: The battery label specifies a 30C discharge rating.
- Three-Lead Configuration: Includes a Deans-style T-plug main power lead, a universal receiver power lead, and a separate JST-XH balance lead.
- 12 AWG Main Power Wire: Heavy-gauge wiring on the main power lead.
- Slim Profile: Measures 5.31 × 1.65 × 0.59 in (135 × 42 × 15 mm) and weighs 7.76 oz (220 g).
🔧 On-Board Integration Wiring Options
Option 1: Main Power Lead Connection
Use the Deans-style T-plug main lead when connecting to a compatible regulator, heavy-duty switch, or power distribution system.
- Connect the battery's main T-plug to a matching input or correctly wired adapter rated for your system's current requirements.
- If any connected equipment does not support 8.4V, use a suitable voltage regulator or external BEC.
- Connect the system's outputs according to the receiver or power distribution manufacturer's instructions. A heavy-gauge adapter alone does not increase the current rating of a receiver port.
Option 2: Direct Receiver Connection
The universal receiver lead may be used for systems whose voltage and current requirements are compatible with this connection.
- Confirm that the receiver and all connected equipment support direct 2S LiPo power up to 8.4V.
- Use the receiver's approved battery input or another port specifically permitted for power input in its manual. Do not assume that every BIND or DATA port accepts battery power.
- Check Polarity: Match the black negative wire and red positive wire to the receiver's marked terminals. Follow the receiver manual rather than relying on connector orientation alone.
- Secure the battery and wiring. Insulate and secure unused connectors away from moving linkages and conductive parts.
Both power leads connect to the same battery pack; they are not independent or redundant power supplies.

🔌 Charger Connection Guidelines
Use a compatible LiPo balance charger set for a 2S, 7.4V LiPo battery. Follow the charger manual to connect the Deans-style T-plug through a matching charge cable and the JST-XH balance lead to the appropriate balance connection. Use the battery manufacturer's specified charge rate; the 30C discharge rating is not a charging rate.
Never charge unattended. Do not charge or use a damaged or swollen battery. Keep the unused receiver lead insulated and secured during charging.
