High-Performance UAV Power from a Dedicated Drone Battery Manufacturer

Shenzhen Jianheng Technology Co., Ltd. builds the OID9787187SS-27000-51.8V pack for professional UAV programs that demand reliable energy in the air. This 51.8V 27000mAh battery uses a 14S semi-solid state lithium chemistry, giving integrators a practical balance of usable capacity, steady voltage delivery and reduced pack mass for extended sorties.

It is aimed at demanding airframes including industrial inspection drones, mapping and surveying UAVs, security and surveillance platforms, agricultural aircraft and heavy-lift systems. The semi-solid electrolyte approach supports consistent discharge under high propulsion loads while offering a strong safety margin and long service life.

Key Strengths of This Drone Battery Pack

High Energy Density for Longer Missions

With gravimetric energy density of at least 255Wh/kg, the pack lets 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.
