2. Setup

2.1 Initial Charging

Before first use, fully charge the battery. It is crucial to use a charger specifically designed for LiFe (Lithium Iron Phosphate) batteries. Do NOT attempt to charge this battery using chargers set for LiPo (Lithium Polymer) or Li-ion (Lithium-ion) battery types, as this can lead to damage or safety hazards due to different voltage requirements.

• Connect the battery's balance and discharge connectors to your compatible LiFe battery charger.
• Select the 'LiFe' charging program on your charger. Ensure the voltage setting matches the battery's nominal voltage (6.6V).
• Initiate the charging process. Charging times may vary depending on the charger's output and the battery's initial charge level, but typically a full charge can be achieved quickly.
• Once charging is complete, disconnect the battery from the charger.

2.2 Installation

Install the fully charged battery into your compatible Futaba transmitter or other device according to the device's specific instructions. Ensure the connectors are securely and correctly seated to prevent intermittent power or damage.

3. Operating Instructions

Once installed and charged, the Futaba 6.6V 2100mAh LiFe battery provides reliable power for your device. The battery is designed to offer a long operational duration, reducing the frequency of recharges during use.

• Always ensure your device is powered off before installing or removing the battery.
• Monitor your device's battery level indicator during operation to avoid complete discharge, which can reduce battery lifespan.
• For optimal performance, avoid operating the battery in extreme temperatures.

4. Maintenance

Proper maintenance extends the life and performance of your Futaba LiFe battery.

• Charging: Always use a dedicated LiFe charger. Avoid overcharging or undercharging.
• Storage: For long-term storage, charge the battery to approximately 50% of its capacity. Store in a cool, dry place away from direct sunlight and extreme temperatures.
• Discharge: Avoid deep discharging the battery, as this can negatively impact its lifespan.
• Cleaning: Keep the battery and its connectors clean and free from dust or debris.
• Cycle Life: The battery is rated for approximately 500 charge/discharge cycles. Adhering to proper charging and usage practices will help achieve this lifespan.

5. Troubleshooting

5.1 Battery Not Charging

• Incorrect Charger Setting: Ensure your charger is set to the 'LiFe' battery type, not LiPo or Li-ion. This is a common cause for charging errors.
• Loose Connection: Check that all battery and charger connections are secure.
• Charger Malfunction: Test the charger with another compatible battery if possible, or try a different charger.
• Battery Damage: Inspect the battery for any visible signs of damage or swelling. If damaged, discontinue use immediately.

5.2 Short Operating Time

• Incomplete Charge: Ensure the battery is fully charged before use.
• Battery Age/Cycles: As batteries age and accumulate cycles, their capacity may decrease.
• Environmental Factors: Extreme cold can temporarily reduce battery performance.
