The Falcore Drone is powered by a LiPo (lithium polymer) battery. Serious injury and damage can result from improper charging and/or use of the lithium polymer battery. All of the instructions and precautions must be read carefully and followed exactly before charging or operating the drone with the LiPo (Lithium Polymer) battery.

Warning:

Incorrect use of the LiPo battery can cause fire, property damage and serious injury. In case of an emergency situation, take all necessary and reasonable measures to prevent expansion of the damage.

General Safety

  • Charging: The cell must be properly connected to the Reverse charging is prohibited. The polarity must be confirmed before connecting. If the battery is not connected properly, it cannot be charged. Reverse charging can cause battery damage which can lead to safety and performance degradation and could cause heat generation or  leakage.
  • Do not strike the battery with any sharp edge objects.
  • Trim your fingernails or wear a glove before taking hold of the battery.
  • Do not disassemble the battery in any way.
  • Do not open or deform the folding edge (covering) of the battery.
  • Do not drop, hit or bend the battery body.
  • The battery must not be used if it is cracked, punctured or leaking electrolyte If electrolyte fluid comes into contact with the skin or eyes, have a physician flush the electrolyte immediately with fresh water and seek further medical advice.
  • Do not incinerate or burn the battery in any way. This is extremely dangerous and prohibited.
  • Do not immerse the battery in liquid.
  • Battery replacement must be done by either the cell supplier or the device supplier and must never be done by the user.
  • The battery might have been damaged during shipping. In case of damage to any part of the battery casing, electrolyte leakage, electrolyte smell or other signs of damage, DO NOT use the In case of electrolyte leakage or electrolyte smell, be especially careful to keep the battery away from fire.
  • If the battery becomes damaged, hot or begins to swell, perform the following procedure:
    1. Stop charging or operation (discharging) immediately.
    2. Quickly and safely disconnect the battery from the charger or Drone.
    3. Place the battery and/or charger in a clear, open area, away from flammable materials and, preferably, inside a fireproof container (such as a LiPo safety bag).
    4. After one hour, if the battery condition has stabilized, remove the battery from Do not continue to handle, attempt to use, or ship the battery. Properly dispose of the battery.

Note:

Failure to follow this procedure can cause property damage or serious injury.

Before Charging

  • Use the provided charger.

Note:

The charger will not charge the battery if the battery voltage has dropped below safe levels.
  • Before charging, always check the battery for damage, paying special attention to: battery packaging, wires and Do not charge a damaged LiPo battery.
  • Use only the connector provided with the drone battery.
  • Check the polarity of the battery cable and charger lead carefully before connecting to avoid any short circuit.
  • Before each charging, verify that the charger is in good A damaged charger can be dangerous.
  • It is the user’s responsibility to ensure that the charger works properly.

Charging

  • It is recommended to use the charger provided with Falcore.
  • You may use another suitable, high quality charger specifically intended for charging lithium polymer batteries.
  • Do not use a NIMH/NICD/LIFEPO4/LEAD ACID charger. If the charger can support different battery types, you must select the LiPo charging Failure to do so may cause fire, which can result in personal injury and property damage.
  • The Falcore battery charger is suitable for rechargeable LiPo batteries DO NOT attempt to recharge dry cells. Charging any battery other than a LiPo battery may cause fire or explosion.
  • Do not use an inferior quality charger.
  • Charge the battery in an open area away from flammable materials, liquids and surfaces.
  • Do not attempt to charge a dead, damaged or wet battery.
  • Do not attempt to charge a battery pack containing different types of batteries.
  • Do not allow children under 13 years of age to charge the battery.
  • Do not charge the battery in extremely hot or cold places or in direct sunlight.
  • Do not charge the battery if the cable has been pinched or shorted.
  • Do not connect the charger if any of the cables on the battery or charger have been pinched or shorted.
  • Do not connect the charger to an automobile 12V battery while the vehicle is running.
  • Do not attempt to dismantle the charger or use a damaged charger.
  • Do not cover the cooling slots during charging.
  • Do not charge the battery when it is connected to the drone.
  • Do not charge the battery when it is hot to the touch (above 100˚F/38˚C). Do not handle the battery until it is cool.
  • The provided charger automatically detects the cell count. When using a charger other than the one provided, the following precautions may apply:

»   Verify that the charger is set to the correct cell count and/or voltage listed on the battery labels.

»   Always set the charger to the amp charge rate as listed on the battery labels.

» Do not set the charger to charge the battery at a rate greater than 1C (One (1) times the capacity of the battery in amp hours, e.g. for a 1400maH battery, set the charger to 1.4A) unless another C rate is specified in the manufacturer’s product documentation or the rate is preset as part of a specific battery and charger combination. Do not alter the charge rate once charging has begun.

»   Do not overcharge the battery beyond the capacity listed on the the battery label.

»   Do not charge the battery past its rated maximum voltage (4.2V/cell for LiPo).

»   Using a LiPo sack is recommended to ensure charging safety.

  • Do not leave the charger unattended during the charging Always monitor the charging process to ensure that the battery is charging properly. Failure to monitor the charging process can result in a fire.
  • Stop charging when the battery has reached maximum Leaving the charger and the battery connected when the battery is fully charged can damage the battery and result in property damage and serious injury.

Operation

  • Do not allow the temperature of battery to exceed 140˚F during drone The battery requires adequate cooling especially when operating at or near maximum capacity.
  • Do not discharge the battery below the voltage for which it is rated by the manufacturer when measured under load (connected to the vehicle or a charger capable of discharge). Discharging the battery to a voltage lower than the lowest approved voltage can cause loss of battery performance and increases the possibility of fire when the battery are charged.
  • Do not discharge battery to a level below 3V per cell under load.
  • The recommended minimum operating voltage is 3.5V per cell.
  • Do not operate the drone at full motor power constantly for more than a few seconds.
  • Monitor the battery temperature and charge level during drone operation and react to potential problems that may occur.
  • In case of emergency , immediately turn off the drone power, disconnect the battery, place it in an open area away from flammable materials, liquids and Observe the battery for approximately one hour. The battery may leak and the reaction with air may cause the chemicals to ignite, resulting in a fire.
  • Check the conditions of the battery before using or discharging Stop using it if you find the cells to be not balanced, puffing or leaking.

Storage

  • The battery balance plug and terminal must not be in contact with any This will short-circuit the battery, resulting in heat and electrical discharge.
  • Do not store loose batteries The battery balance plugs or terminals can come into contact with one another causing a short circuit.
  • Do not store the battery in extreme temperatures or in direct sunlight. The safe short term storage temperature range is: 14° F (-10˚C) to 13°F (45˚C).
  • To store the battery for an extended period of time (over 3 months), do the following:
    1. Operate the drone until the low battery indicator appears.
    2. Charge the battery for 1 hour.
    3. Maintain the following environmental conditions:

»   Temperature: 73° ±9°F (23° ±5°C)

»   Humidity: 65 ±20% RH

»   Voltage: 3.6V ~ 4.2V range per cell

  • Always disconnect battery from the charger or drone when not in use and store it in a non-conductive, fireproof container.
  • Do not alter, puncture or impact batteries or related components.
