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.
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.
