As the autumn farming season approaches, agricultural drones are taking to the skies to assist in crop management tasks. These drones rely on powerful batteries to perform their duties efficiently and safely. However, proper maintenance and handling of these batteries are crucial to ensure their longevity and safety during operation.CTECHi, a leading provider of agricultural drone batteries with 19 years of experience, offers valuable insights into maintaining and caring for these intelligent batteries. Here are some essential tips for agricultural drone battery maintenance and emergency handling:Avoid Over-Discharging: It's important to use intelligent batteries within their recommended voltage range to avoid over-discharging, which can damage the battery or even cause a drone malfunction. To prolong battery life, avoid deep discharges during normal operations.Handle with Care: Handle batteries with care to prevent physical damage that could compromise their safety. Ensure batteries are securely fastened to the drone to prevent them from dislodging during dynamic flight maneuvers or crashes.Optimal Charging Conditions: Avoid charging batteries in extreme temperatures, as this can affect performance and longevity. Store batteries in a cool, dry environment, ideally between 10-25°C, and avoid exposure to direct sunlight or heat sources during charging.Separate from Chemicals: Keep batteries away from agricultural chemicals to prevent corrosion and damage. After completing operations, wipe down batteries to remove any residue and store them separately from chemicals to minimize the risk of corrosion.Regular Inspection: Inspect batteries regularly for signs of damage, deformation, corrosion, or leakage. Clean battery surfaces and connectors after each use to remove any residue. Ensure batteries have cooled to below 40°C before charging to optimize charging efficiency and safety.Emergency Handling: In the event of a battery fire during charging, immediately disconnect the charging system and remove the burning battery using appropriate safety gear. Smother the fire with a fireproof blanket or sand to extinguish it and prevent further damage.Remember to dispose of depleted batteries safely by soaking them in saltwater for at least 72 hours to fully discharge them before drying and disposal.By following these maintenance and handling guidelines, agricultural drone operators can ensure the safe and efficient operation of their batteries, minimizing the risk of accidents and prolonging battery life.

As electric-powered unmanned aerial vehicles (UAVs) become increasingly prevalent, the proper usage of UAV batteries is crucial for ensuring both flight safety and battery longevity. CTECHi's intelligent UAV warehouse, utilizing RFID technology, offers standardized management for UAV operations, enhancing safety and efficiency.CTECHi's smart battery charging cabinets allow users to monitor battery quantity, status (charging, fully charged, stored, communication failure, etc.), current capacity, temperature, SN code, charging cycles, usage history, lifespan, damaged batteries, and active batteries through the intelligent warehouse management system.Here's some essential information regarding UAV batteries:Basic Structure of Lithium-ion UAV Batteries:Positive electrode: Typically composed of lithium cobalt oxide or lithium nickel cobalt manganese oxide.Negative electrode: Composed of graphite or graphite-like carbon.Positive electrode tab: Made of aluminum (Al) composite.Negative electrode tab: Made of nickel (Ni) or nickel-plated copper (Ni-Cu) for good conductivity.Electrolyte: Consists of lithium hexafluorophosphate dissolved in carbonate solvent or gel-like electrolyte.Separator: A specialized polymer film with microporous structure.Voltage System of UAV Lithium-ion Batteries: UAV batteries are classified into high-voltage system batteries (rated voltage 3.8V, charging upper limit voltage 4.375V) and conventional voltage system batteries (rated voltage 3.7V, charging upper limit voltage 4.25V).Avoid Over-discharge: To prevent battery damage or potential hazards like internal short circuits, UAV batteries should not be discharged below 2.5V per cell.Avoid Overcharge: Specialized chargers should be used to prevent overcharging, as it may reduce battery lifespan or lead to thermal runaway and fire hazards.Partial Charging for Storage: Fully charged batteries should not be stored for more than seven days. For long-term storage, batteries should be charged to 3.80-3.96V per cell.Long-term Storage: If batteries are not used for more than three months, they should be cycled once before adjusting the voltage to 3.80-3.96V per cell for storage.Protection from Physical Damage: UAV batteries should be protected from dropping or impact to avoid deformation and internal short circuits, which can accelerate battery degradation or cause fires.Avoid Contact with Sharp Objects: Direct contact with sharp objects should be avoided to prevent packaging damage and electrolyte leakage, which may lead to battery failure or combustion.By adhering to these guidelines, UAV operators can ensure the safe and efficient use of lithium-ion batteries, thereby maximizing the performance and lifespan of their UAVs.

As the drone industry continues to evolve, polymer lithium batteries have emerged as the preferred choice for powering drones. But what advantages do polymer lithium batteries offer as drone batteries, and how are they utilized in practical applications?Flexibility in Size and Shape: Polymer lithium batteries are not restricted to standard sizes and can be flexibly designed in various dimensions, including thickness. Unlike conventional liquid lithium-ion batteries, polymer batteries can be as thin as 1mm, allowing for more versatile design options and maximizing the use of valuable space in drones.Enhanced Discharge Performance: With gel electrolytes, polymer lithium batteries exhibit more stable discharge characteristics compared to liquid electrolytes. This results in approximately 20% higher energy density and superior capacity compared to conventional lithium-ion batteries, making them ideal for powering drones.Lower Internal Resistance: The gel electrolytes used in polymer lithium batteries contribute to lower internal resistance. This translates to reduced self-discharge and extended standby time, enabling drones to deliver higher performance. Leading manufacturers like CTECHI have achieved industry-leading levels of internal resistance in their polymer lithium batteries.Enhanced Safety Features: Polymer lithium batteries, with their aluminum-plastic soft packaging, have a lower risk of explosion compared to batteries with metal casings. In case of a safety hazard, they are more likely to swell rather than explode, ensuring a higher level of safety for drones and their operators.Lightweight Design: By eliminating the need for metal casing, polymer lithium batteries are lighter compared to batteries of similar capacity. This lightweight design is advantageous for drones, allowing for longer flight times and improved overall performance.One notable example of a polymer lithium battery designed for industrial drones is the 14S30Ah intelligent battery produced by CTECHI.
