OID 9987191 39Ah 3.7V 2C High Rate LiPo Drone Battery

OID1088191-39000mAh-3.7V-2C-0102 39Ah 3.7V High Rate LiPo Drone Battery

Jianheng presents the OID 9987191, a high-performance lithium-ion polymer battery specifically engineered for demanding drone and UAV applications. This cell delivers a robust 39Ah typical capacity and a nominal voltage of 3.7V, providing extended flight times and reliable power for professional and recreational unmanned aerial vehicles. With an ultra-low internal resistance of less than 2mOhm, it ensures minimal voltage drop and high efficiency during high-current discharge.

Key Features and Superior Performance

The OID1088191-39000mAh-3.7V-2C-0102 is optimized for high-rate applications, offering a maximum continuous discharge current of 78A (2C) and a burst discharge current of up to 195A (5C). This makes it an ideal power source for high-performance drones that require sudden bursts of power for takeoff, maneuvers, and payload lifting. Its exceptional low-temperature discharge capability, retaining over 60% capacity at -20C, ensures reliable operation in various environmental conditions, a critical factor for outdoor drone missions.

  • High capacity: 39Ah (typical) for extended drone flight times.
  • Ultra-low internal resistance: <2mOhm for high efficiency and power delivery.
  • High discharge rate: Supports 2C continuous (78A) and 5C burst (195A) currents.
  • Excellent low-temperature performance: Over 60% capacity at -20C.
  • Robust cycle life: Retains over 80% capacity after 300 cycles.
  • Reliable safety and environmental performance: Certified with UN38.3 and MSDS.
