Safety Instructions

Users must use the battery within the operating environment specified in this battery specification sheet. If use outside the specified environment is required, users must consult our company for risk assessment.
    Our company assumes no responsibility for accidents that occur when the battery is used outside the environment specified in this specification sheet.
    The charging current of a single cell should be less than the maximum charging current specified in this specification sheet.
    The charging temperature of the cells must strictly comply with the temperature specified in this specification sheet. Charging above or below the specified temperature range is strictly prohibited.
    When the battery voltage drops to 0V, charging the battery is prohibited.
    The discharge current must not exceed the maximum discharge current specified in this specification sheet. Excessive discharge current will cause cell overheating and rapid capacity degradation.
    Due to self-discharge, batteries stored for long periods may be in an over-discharged state. Therefore, batteries in long-term storage should be periodically charged to prevent over-discharge. Over-discharge may cause battery swelling and deformation as well as rapid capacity degradation.
    Batteries should be stored under the temperature and humidity conditions specified in this specification sheet. The voltage of batteries in long-term storage should be maintained between 66.6V--69.3V.
    Do not use sharp objects to contact or scratch the battery.
    Disassembling, opening, crushing, bending, twisting, or cutting the battery is strictly prohibited. Such actions may cause internal short circuits and result in fire.
    Unauthorized modification or alteration of the battery is prohibited. Do not attempt to insert foreign objects into the battery.
    Do not immerse the battery in water or other liquids, or expose it to fire, explosion, or other hazardous environments.
    Always use the battery in the system for which it was designed.
    Always use a certified and qualified charging system. Using uncertified chargers may cause fire, explosion, leakage, or other hazards.
    Do not short-circuit the battery or allow conductive metal objects to contact the positive and negative terminals.
    Dispose of used batteries properly or in accordance with local regulations.
    Improper use of the battery may lead to fire, explosion, or other hazards.
    In case of battery leakage, prevent battery fluid from contacting skin or eyes. If contact occurs, immediately flush with large amounts of clean water and seek medical attention promptly.
    Do not incinerate the battery or place it in fire, as this may cause an explosion.
    Do not use damaged batteries. Batteries may be damaged during transportation. If any abnormalities are observed, such as deformation or damage to battery packaging, electrolyte leakage, or unpleasant odor, the battery should be immediately discarded and must not be used.
    There must be sufficient insulation between battery leads and individual cells to ensure the battery pack does not short-circuit.
    Users are strictly prohibited from replacing battery cells.
    Installing the battery on the drone during transportation is strictly prohibited.

Product Overview

The 18S2565Wh Smart Battery is a high-capacity, high-discharge-rate, long-life smart battery. It utilizes a ternary high-voltage system with 18 built-in cells, a full charge voltage of 78.3V, a unified charging and discharging port, and a dedicated connector for the power plug, with a continuous discharge current of up to 380A.

  • If short circuit/startup current is too high, disconnect the battery and check if there are foreign objects at the connection between the battery and the aircraft. If startup voltage is too low, the battery needs to be charged before use.
  • If battery temperature is abnormal, wait for the temperature to return to normal before resuming normal use..
  • If the battery cannot be properly installed in the aircraft or charger battery compartment, clean the connection ports of the battery, aircraft, and charging equipment, then reinstall the battery.
  • For other abnormalities, after troubleshooting, turn off the battery power and after 60 seconds, turn it back on.

2
Storage Environment
Recommended storage temperature:  32°F-113°F, humidity: 40%-70% RH. Avoid prolonged exposure to extreme temperatures (<-68°F or >113°F).
3
Storage Precautions
Keep dry, away from water sources;
Keep away from heat s ources;
Place on a flat surface to avoid sharp objects damaging the casing;
Scrapped or faulty batteries must be stored in isolation;
Do not store together with flammable or explosive materials.
4
Placement Method
Do not stack or invert. Do not place heavy objects on top of batteries;;
When storing multiple batteries, maintainrecommendedspacing greater than 30cm;
Multi-tier rack storage must consider weight capacity to prevent collapse.
5
Regularly check
Regularly check battery condition. If severe continuous heating occurs, contact after-sales service promptly.
6
Fire Safety
Storage sites must be equipped with fire-fighting equipment such as sand, water buckets, and fire extinguishers;
In case of fire, use water or sand to extinguish. After the open flame is extinguished, fully submerge the battery in concentrated salt water (above 5%) for more than 24 hours.

Emergency Safety Procedures

Electrolyte Leakage Handling

If electrolyte contacts skin, eyes, or other body parts, should immediately flush with large amounts of clean water and as soon as possible and seek medical attention promptly.

Fire Emergency Handling

    Fire equipment preparation: Equip with heat-resistant gloves, fire tongs, fire blankets, fire extinguishers, fire sand, fire buckets, fire shovels, etc.
    Fire Handling:
  • Immediately move away from the burning battery, disconnect it from electrical equipment, or transfer the equipment to an open area as soon as possible.
  • Stand in a safe area. Preferably use dry powder or water-based fire extinguishers to suppress open flames, or place the battery or charging equipment in fire buckets filled with sand to isolate oxygen;
  • Lithium batteries are highly prone to reignition after being extinguished. Keep them in a safe area and monitor continuously for more than 24 hours. If possible, place in explosion-proof containers or submerge in concentrated salt water;
  • After the fire is extinguished, do not disassemble or discard the battery on your own. Contact the fire department, manufacturer after-sales service, or professional battery disposal agencies for proper hazard-free treatment.

Maintenance and Care

Safety Standards

  • Only use the matching dedicated charger for charging and discharging, charging voltage must not exceed 78.3V.
  • Strictly follow safety standards. Charging is prohibited when battery temperature is below 32°F or greater than 149°F.
  • During charging, monitor indicator light status. If a red fault light appears, immediately stop charging and investigate the cause of the fault.
  • Keep fingers clean and dry when handling the battery to avoid sweat or moisture infiltration.
  • Faulty batteries must be labeled with a " Used Part Identification Card" (Appendix 1) with accurate fault information recorded.

Daily Cleaning

  • Use a clean dry towel to wipe the battery exterior. Clean the charging/discharging port with a cotton swab dipped in alcohol and perform cleaning.
  • If the port turns black or shows corrosion, immediately stop using the battery and contact after-sales service.

Long-term Storage and Maintenance

  • For storage exceeding 3months, it is recommended to store in a temperature 32°F-113°F and humidity40%-70% RH environment.
  • At least every 3 months, perform a complete charge-discharge cycle, strictly following storage requirements.
  • Do not leave the smart battery in high-temperature, rain/snow, humid, or prolonged direct sunlight environments for extended periods.
  • Keep away from heat sources, high voltage, water, flammable and explosive gases, strong corrosion, and other hazardous environments.
