Power Unlimited 2S 1600mAh 6.6V 20C LiFe Receiver Battery

The Power Unlimited 1600mAh 2S LiFe receiver battery provides onboard power for compatible RC receiver and servo systems. Its flat profile offers a convenient fit where battery compartment space is limited.

A JR universal receiver plug and JST-XH balance connector provide connections for onboard use and balance charging.

🚀 Target Applications:

  • Onboard radio system power for compatible RC airplanes and sailplanes
  • Dedicated receiver battery configuration for installations requiring a flat profile pack
  • Models requiring a 6.6V nominal power source with low operational space constraints

⚠ Compatibility & Charging Warning:

  • Voltage Compatibility: Confirm that your receiver, servos, switches, and other connected equipment support a fully charged 2S LiFe battery. Nominal voltage alone does not determine compatibility.
  • Program Selection: Use a balance charger with the correct LiFe charging mode and follow the battery instructions. Do not charge using a LiPo program. Never leave a charging battery unattended.

Key Features

  • 1600mAh Capacity: Reliable dedicated power delivery for compatible airborne radio gear.

💡 Modeler's Installation and Setup Guide

Test-fit the LiFe pack inside your model's radio bay to confirm length and width clearance before final securement. Insert the JR universal plug directly into your receiver's BATT port or an open channel lane, taking care to check wire polarity matching. Ensure all battery leads are bundled cleanly away from moving servo horns or mechanical pushrod paths.
