Product Description

High-Energy 59.29Wh UAV Battery, 4S 15.4V 3850mAh LiPo for Professional Drones, Max Power & Extended Performance

Features

  • High Volumetric Energy Density: Delivers 59.29Wh of energy in a compact package (98x59x45mm), enabling longer runtimes for power-hungry devices.
  • High Specific Energy : The lightweight design (under 300g) provides an excellent power-to-weight ratio, crucial for aerial and mobile applications.

  • High Discharge Rate Capability: Designed to deliver high burst currents (depending on C-rating), suitable for applications with sudden high-power demands.

  • Stable Voltage Plateau: Provides consistent power delivery for the majority of the discharge cycle.

  • Rugged Construction (Typical): Often features a hard case or robust shrink-wrap for improved physical protection against vibration and minor impacts.

Warnings & Precautions


Charging


  • Charger Compatibility: MUST use a smart balanced charger designed for LiPo/LiHV chemistry. Incorrect charger settings will cause catastrophic failure.
  • Correct Settings: Set the charger to: LiPo Balance Charge, Cell Count: 4S, Voltage: 17.4V (4.35V/cell for HV)Never charge as a standard 14.8V (4.20V/cell) pack.

  • Supervised Charging: Never leave batteries charging unattended. Charge in a fire-resistant container (LiPo safety bag) on a non-flammable surface, away from flammable materials.

  • Charge Current: Do not exceed the manufacturer's specified limit. 1C (3.85A) is standard and safe. 2C (7.7A) may be acceptable if specified.


Discharging


  • Voltage Monitoring: Never discharge below 12.0V (3.0V per cell). Use a battery monitor or low-voltage cut-off (LVC) on your device. Over-discharge ruins cells and creates safety risks.
  • Temperature Management: Discontinue use if the battery pack exceeds 60°C (140°F). Allow it to cool completely before handling or recharging.

  • Short Circuit Prevention: Always insulate terminals when not in use. Use connectors carefully to avoid accidental shorting, which can cause instant, severe fires.

  • Damage Inspection: Before and after each use, inspect for physical damage: dents, swelling, punctures, or leaking electrolyte. IMMEDIATELY DISCONTINUE USE of any damaged or swollen/puffy battery.


Storage


  • Storage Voltage: For storage over one week, bring the battery to storage voltage .
  • Storage Environment: Store in a cool, dry place, away from direct sunlight and flammable items.

  • Transportation: When transporting (e.g., to a flying field), place each battery in an individual LiPo safety bag. Protect terminals with caps or tape.

  • End-of-Life Disposal: Do not discard with household waste. To safely dispose, fully discharge (e.g., in a saltwater bath for several days), then take to a designated battery recycling facility.
