4. Setup: Charging Instructions

Follow these steps to safely charge your URGENEX Li-ion batteries:

1. Connect the USB charger to a compatible power source (e.g., a computer USB port, power bank, or wall adapter with DC 5V 2A output).
2. When the charger is powered on without any battery connected, the red indicator light will be solid.
3. Connect the JST-XH balancing connector of the battery to one of the charging ports on the USB charger. Ensure the connection is secure and correctly oriented.
4. During charging, the charger's indicator light for that port will show a solid red light and a flashing green light.
5. Once the battery is fully charged, the indicator light will turn solid green.
6. Disconnect the battery from the charger immediately after it is fully charged. Do not leave batteries unattended while charging.
7. The charger supports charging two batteries simultaneously, with each output port operating independently.

6. Maintenance and Storage

• Charging: Always use the provided URGENEX charger or a compatible Li-ion charger. Do not overcharge or over-discharge the battery.
• Storage: Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, charge the battery to approximately 50% of its capacity.
• Temperature: Avoid exposing batteries to temperatures below 0°C (32°F) or above 60°C (140°F).
• Physical Damage: Do not puncture, drop, or disassemble the battery. If the battery appears damaged, swollen, or leaking, discontinue use immediately and dispose of it properly.
• Cleaning: Keep battery terminals clean and free from dirt or corrosion.

7. Troubleshooting

Battery Not Charging:

• Check Connections: Ensure the USB charger is securely plugged into a power source and the battery's balancing connector is firmly attached to the charger.
• Verify Power Source: Confirm the USB power source (laptop, power bank, wall adapter) is functioning correctly and provides DC 5V 2A output.
• Inspect Battery: Check the battery for any visible damage, swelling, or leaks. Do not attempt to charge a damaged battery.
• Charger Indicator: Refer to the "Charger Indicator Light Status" table in Section 4 to understand the charger's current state. If the indicator lights do not behave as expected, the charger or battery may be faulty.
• Try Another Port/Battery: If charging multiple batteries, try a different charging port or a different battery to isolate the issue.

Short Run Time:

• Full Charge: Ensure the battery is fully charged before use (solid green indicator on charger).
• Battery Age/Cycles: Li-ion batteries degrade over time and with charge cycles. After approximately 300 cycles, performance may decrease.
• Environmental Factors: Extreme cold temperatures can reduce battery performance.
• Vehicle Load: High-demand RC applications or heavy vehicles will naturally consume power faster.

8. Safety Information

Lithium-ion batteries can be hazardous if not handled properly. Please observe the following safety precautions:

• Charging Safety:
  • Always charge batteries on a non-flammable surface and away from flammable materials.
