or serious injuries.

WARNING!

Read the ENTIRE user manual to get familiar with the features of this product before operating. Failure

to operate this product properly can result in damages to the product or personal property and cause

serious injuries. This product is designed for use with drones. The use of this product is very

sophisticated. It must be operated with caution and common sense and will take some time to get

familiar with it. Lack of strong safety consciousness or misoperation can result in damages to the

product and other devices connected to the product and personal property, and even serious injuries.

This product is not intended for use by children. Make sure to strictly follow the instructions in the User

Manual. This Safety Guidelines contains instructions on safety, operation and maintenance. Make sure

to read and follow all of the instructions and warnings in the Safety Guidelines and the User Manual

before assembling, setting or using this product.

RC Battery Safety Guidelines

WARNING: Failure to charge or store the battery properly can result in fire, property damage or

serious injuries. Make sure to use the battery in compliance with the following safety

guidelines.

1. Do not disassemble the battery by yourself. Removing the built-in battery is not allowed. Please

replace the battery at after-sales service offices.

2. The ambient temperature for battery should be 10-40°C. If the temperature is too high (higher than

60°C), the battery may catch fire and even explode. If the ambient temperature is too low (lower than

10°C), the battery life may be shortened.

3. Do not disassemble the battery in any way, or it may catch fire and even explode.

4. Battery electrolyte is highly corrosive. Keep away if there is a leak. If any electrolyte contacts your

skin or eyes, immediately wash affected areas with fresh running water for at least 15 minutes and see

a doctor immediately.

5. If there is a fire caused by improper use of the battery, we recommend you use solid fire extinguisher

in the following order: Water or mist water, sand, fire extinguisher blanket, powder and Co2

extinguishers.

6. Do not put the battery in a microwave oven or pressure cooker.

7. Do not put battery cells on any conductive surfaces.

8. Do not use wires or any other metal objects to short-circuit the positive and negative poles of the

battery.

9. Do not strike the battery. Do not place anything heavy on the battery or the charger.

10. Do not throw th e battery into th e fire or place the unused battery near heat sources.

Otherwise, the insulation pro tection layer in the battery will be melte d and the safe ty valve and

other structures will be destroyed. The battery will ov erheat and may catch fire or even explode.

11. Always use batteries recommended by Feima. Feima is not responsible for any battery-related

accidents or flight failures caused by using non-Feima batteries.

Charging

1. The charger is only applicable for specified product in accordance with certain instructions.

2. Always use Feima approved charger. Feima is not responsible for any consequences caused by

using non-Feima chargers.

3. When charging, put the RC and the charger on cement floor or other grounds where there is no

flammable objects. Take care and avoid any accidents.

4. Do not charge the battery when the ambient temperature is too high (≥45°C) or too low (≤0°C) The

ideal ambient temperature for charging (10-40°C) can greatly extend battery life.

5. Do not continue to charge the battery if it is not fully charged within the set time, or it may cause

overheat, fire or explosion.

6. Unplug the charger fo rm the RC once it is fully charged. Chec k and ma intain the charger

regularly. Do not clean the charger and t he battery with alcohol or any ot her flammable

cleaners. Do not use da maged charger.

Battery Safety Guidelines

Storage and Transportation

1. Keep the battery out of the reach of children. If the child swallows the components, seek emergency

medical assistance without any delay.

2. Do not leave the RC near heat sources such as in direct sunlight, in a furnace, heater or inside the

car in hot days. The ideal storage temperature is 22-28°C.

3. Keep the battery dry. Do not place the battery in water or where it may leak.

4. Do not strike, crush or impale the battery. Do not drop the battery or manually short-circuit the battery.

5. Do not storage or transport the battery together with glasses, watches, jewelry, hairpins and other

metal objects.

6. Do not transport damaged batteries. Discharge the battery to lower than 30% for air transportation.

7. Never put the battery in ESD protected areas beyond those defined by the manufacturer, or it may

damage the battery protection mechanism and result in overheat, explosion or fire.

8. All the batteries are up to certain specification during manufacturing and checking before delivery.

Return the battery to where it was purchased if you find anything abnormal regarding its smell,

Disposal

Dispose of end-of life batteries into specific recycling boxes only after they are fully discharged. Do not

simply dispose of batteries into regular garbage bins. The disposal and recycling of batteries is subject

to detailed local rules and regulations.

Maintenance

1. Never use the charger when the ambient temperature is too high or too low.

2. Never storage the battery where the temperature is higher than 60°C.

3. Fully charge the battery and keep it at appropriate temperatures before flying at low temperatures (-

10~5°C), or the battery capacity will be significantly reduced which may lead to much shorter flight time.

4. Never use the battery in environments with a temperature lower than 10°C.

5. When flying at low temperatures (-10~5°C), preheat the RC to higher than 5°C (higher than 20°C will

be better) before using.

Storage and Transportation

1. Discharge the battery to 60-75% if it will not be used for 10 days or more. This can extend the battery

life. Discharge fully charged batteries with the RC.

2. Do not store the battery for a long time after fully discharging it, for example, when the RC battery

runs out. Otherwise, you may risk over-discharging the battery which may lead to irreparable damage to

the battery cells.

3. Recharge the battery to 60-70% every 2 months, and make adjustments based on the actual storage

conditions and power consumption of the system.

4. The battery will enter hibernation mode if it has been depleted and idled a long period. Recharge the

battery to bring it out of hibernation.

5. Remove the battery from the aircraft for long-term storage.

Maintenance

1. Never overcharge the battery or it will do harm to the battery cells.

2. Keeping the battery idle for a long time will affect its performance.

It is recommended that the battery should be recharged and discharged at least once every

3 months to maintain battery health and extend the battery life.
