Dependable Aerial Power Backed by a Focused Drone Battery Manufacturer

For professional unmanned aerial programs that need trustworthy in-flight energy, Shenzhen Jianheng Technology Co., Ltd. produces the OID9787187SS-27000-51.8V. This pack pairs a 51.8V 27000mAh rating with 14S semi-solid state lithium chemistry, offering integrators a sensible mix of usable capacity, stable voltage delivery and lower pack mass for extended sorties.

It suits challenging airframes such as industrial inspection drones, mapping and surveying UAVs, security and surveillance platforms, agricultural aircraft and heavy-lift systems. The semi-solid electrolyte design allows consistent discharge under heavy propulsion loads while providing a solid safety margin and long service life.

Core Advantages of This Drone Battery Pack

High Energy Density for Longer Missions

With gravimetric energy density of at least 255Wh/kg, the pack helps airframe designers extend flight duration without adding unnecessary weight. More usable energy per kilogram translates into more time on station for inspection, mapping and surveillance work.

Power Delivery for Demanding Propulsion

The 14S configuration provides a nominal 51.8V output suited to high-power propulsion systems. The pack supports continuous discharge as well as higher burst current for take-off, climbing and aggressive maneuvering, so professional platforms can access power when it matters most.

Flexible Charging and Fast Turnaround

Multiple charging modes are supported, including standard charge, fast charge and super-fast charge up to 2C. This flexibility helps operators reduce turnaround time between missions and keep UAV fleets productive.

Reliable Operation Across Temperature Ranges

The pack is designed for professional drone missions in varied environments, with charging permitted from 0°C to 45°C and discharging from -20°C to 60°C. This wide operating window supports deployment across different regions and seasonal conditions.

Cycle Life and Mechanical Reliability

Under standard test conditions, the battery reaches at least 300 cycles while retaining 80% or more of its capacity. This level of endurance supports long operational life for industrial UAV fleets and reduces replacement frequency.

During cycle-life testing, charge follows a 0.5C CC/CV profile to full with a cut-off of 0.05C, while discharge runs at 0.5C to 42.0V. The 27Ah rated capacity, together with these test conditions, defines the pack's expected longevity in fleet service.

The pack also passes strict mechanical reliability tests. Vibration testing from 10Hz to 55Hz at 1.6mm amplitude for 30 minutes per axis, and a 1.2m drop test onto a 30mm wooden board repeated three times, both show no explosion, no fire and no leakage. These results give procurement teams confidence in the pack's durability during transport, handling and flight.
