How to Install

1. Power off your RC receiver system completely before replacing the battery.
2. Measure your receiver’s battery compartment and confirm the selected variant dimensions fit correctly.
3. Open the battery compartment and remove the old battery pack.
4. Insert the new FMA ACE battery into the compartment, aligning it with the housing guides.
5. Connect the Futaba connector to the receiver’s power port — grip the connector body firmly, do not pull or tug the wires.
6. Close the battery compartment and power on the system to verify normal operation.
7. To charge, connect the XH-3P balance connector to a Li-Po balance charger set to 2S / 7.4V (max 8.4V). Always use balance charging mode.
8. For long-term storage, charge to storage voltage (~7.6V / 3.8V per cell) before storing.

Installation Cautions

• ⚠️ Futaba Connector — Critical Warning: The Futaba connector has internal solder joints. Always grip the Futaba connector body firmly when plugging or unplugging — NEVER pull on the wires. Pulling the wires will cause the internal solder joint to detach from the battery terminal, resulting in permanent loss of connection.
• ⚠️ XH-3P Balance Connector: Used for balance charging only — do not use as the main power connection. Connect only to a compatible 2S Li-Po balance charger port.
• ⚠️ Verify dimensions before installation — forcing an oversized battery into a compartment may damage the battery or receiver housing.
• ⚠️ Align all connectors correctly before inserting. Do not force any connector — incorrect orientation may damage the pins.
• ⚠️ Ensure the battery fits snugly without bending or compressing the wires. Pinched wires can cause short circuits.
• ⚠️ Do not route wires across sharp edges inside the battery compartment.
• ⚠️ If the Futaba connector feels loose or the system shows no power after installation, inspect the connector and internal solder joints before use. Contact us if the joint has detached.

Important Cautions

• ⚠️ No PCM protection inside. Always use with a device or charger that provides overcharge and over-discharge protection.
• ⚠️ Use only a Li-Po balance charger set to 2S (8.4V max). Never use Ni-MH or unregulated chargers.
• ⚠️ Never discharge below 6.0V (3.0V per cell). Deep discharge will permanently damage the battery.
• ⚠️ Do not short-circuit, puncture, crush, bend, or expose to fire.
• ⚠️ Do not charge a swollen or damaged battery. Discontinue use immediately if abnormalities are detected.
• ⚠️ Charge in a fireproof LiPo safe bag. Never leave charging unattended.
• ⚠️ Keep out of reach of children.

Safety Information

• Charging: Use a 2S Li-Po balance charger (8.4V max). Charge in a fireproof container. Never overcharge.
• Storage: Store at 3.8V per cell (~7.6V total) in a cool, dry place (15–25°C). Avoid full charge for long-term storage.
• Operation: Do not short-circuit, puncture, crush, or disassemble. Avoid exposure to water or moisture.
• Temperature: Charge and discharge within 0°C–45°C. Do not charge below 0°C.
• Disposal: Discharge to safe voltage, then dispose of according to local lithium battery regulations. Do not incinerate.
• Inspection: Inspect before each use. Do not use if swollen, damaged, or leaking.
