Power Unlimited 2S 850mAh 6.6V 20C LiFe Receiver Battery
The Power Unlimited 850mAh 2S LiFe receiver battery is a compact option for compatible RC airplane radio systems. Weighing approximately 1.66 oz (47 g), it fits installations where battery space and weight matter.
A JR universal plug provides the receiver connection, while a separate JST-XH balance connector allows balance charging with a compatible LiFe charger.
🚀 Target Applications:
- Compact RC aircraft radio installations requiring a lightweight power footprint
- Dedicated receiver battery configuration for setups requiring an alternative to LiPo voltage parameters
- Models with tight, restricted fuselage bays that cannot accommodate standard high-capacity packs
⚠ Compatibility and 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 establish compatibility. Check the battery compartment dimensions and select capacity appropriate for your model's power requirements.
- Program Selection: Use a LiFe-compatible balance charger with the correct cell count and manufacturer-specified charge settings. Do not use a LiPo charging program. Never charge unattended, and discontinue use if the battery is damaged or swollen.
Key Features
- 850mAh Capacity: Space-saving capacity option packaged into a compact two-cell configuration layout.
- 2S LiFe Chemistry: 6.6V nominal voltage baseline delivering an alternative discharge curve to standard chemistries.
- 20C Discharge Rating: Formulated to maintain stable power tracking under common servo loads.
- Receiver Connector: Pre-wired with a standard JR universal plug for common receiver power bus slots.
- JST-XH Balance Tab: Built with a separate balance lead to match conventional computerized balance charge arrays.
- Lightweight Design Profile: Minimal mass addition tips the scales at an ultra-low weight of approximately 1.66 oz (47 g).

💡 Modeler's Installation and Setup Guide
Test-fit the LiFe pack inside your model's radio bay to confirm dimensional and weight constraints before final mounting. Insert the pre-wired JR universal plug directly into your receiver's open BATT port or an available auxiliary channel slot, making sure wire polarity aligns correctly. Secure the battery block firmly away from structural edges and ensure leads clear all physical throw lines of moving servo horns.
