How to Install

1. Power off your RC transmitter completely before replacing the battery.
2. Open the battery compartment and remove the old battery pack.
3. Insert the new FMA ACE battery into the compartment, aligning it with the housing guides.
4. Connect the SYP connector to the transmitter’s power port — push the connector body firmly until it clicks. Do not pull or tug the wires.
5. Close the battery compartment and power on the transmitter to verify normal operation.
6. 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 for cell-level balancing.
7. For long-term storage, charge to storage voltage (~7.6V / 3.8V per cell) before storing.

Installation Cautions

• ⚠️ SYP Connector — Handle with Care: This battery uses an SYP connector with internal solder joints. Always grip the connector body when plugging or unplugging — never pull on the wires. Pulling the wires can cause the internal solder joint to detach from the battery terminal, resulting in loss of connection or battery damage.
• ⚠️ XH-3P Balance Connector: Used for balance charging only — do not use as the main power connection. Connect only to a compatible 2S balance charger port.
• ⚠️ Align all connectors correctly before inserting. Do not force any connector — incorrect orientation may damage the pins.
• ⚠️ Ensure the battery fits snugly in the compartment 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 SYP connector feels loose or the battery 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.
