18S 66000mAh 71.1V 5C Semi-Solid UAV Drone Battery

The AervoPower 18S 66000mAh 71.1V 5C Semi-Solid UAV Drone Battery is a high-performance 71.1V semi-solid state lithium battery pack purpose-built for heavy-payload commercial drones, agricultural spraying UAVs, and long-endurance flight platforms. Leveraging advanced semi-solid chemistry, this battery delivers exceptional gravimetric energy density, robust thermal stability, and superior operational safety compared to conventional liquid-electrolyte LiPo batteries.

Constructed in a 18S configuration with high-grade A4G1N7 semi-solid pouch cells, the pack provides a rated capacity of 66000mAh and 4692.6Wh of nominal energy. Engineered as the high-voltage flagship in the A4G1N7 series, it maximizes system voltage and motor electrical efficiency, designed specifically for heavy-lift commercial platforms that require greater power throughput than 6S, 12S, 14S configurations.

High-Rate Discharge Stability & Flight Dynamics

Engineered for high-current flight regimes, the battery supports up to 5C continuous discharge capability, ensuring rock-solid voltage retention under demanding throttle transitions. Whether executing heavy-payload takeoff, rapid climb sequences, obstacle-avoidance maneuvers, or maintaining level flight against turbulent crosswinds, the pack delivers a flat, predictable discharge curve to maintain stable motor RPM and flight controller telemetry.

Semi-Solid Electrolyte Safety & Thermal Resilience

Safety is critical during high-value aerial operations. The semi-solid state electrolyte matrix drastically curtails combustible liquid solvents, significantly mitigating the risk of thermal runaway, internal micro-shorting, or catastrophic ignition upon mechanical impact or accidental over-discharge. The internal cell architecture ensures uniform current distribution and superior heat dissipation, supporting dependable mission execution across extreme ambient conditions.

Ultra-Long Cycle Life & Fleet Operating ROI

While standard liquid LiPo flight packs often experience severe capacity degradation after 300 to 500 charge cycles, the AervoPower A4G1N7-18S achieves an extended service life rated at ≥2500 Cycles (Capacity Retention ≥80%). This multi-fold expansion in usable flight cycles substantially reduces amortization costs per flight hour, delivering compelling return on investment (ROI) for commercial fleet operators, spraying contractors, and aerial surveying organizations.

Mechanical Packaging & Custom OEM/ODM Integration

With physical dimensions of 186.3(T) x 161(W) x 227(H) mm and an engineered total weight of approximately 19584g (±100g), this battery pack is optimized for drop-in compatibility with standard commercial drone battery trays. AervoPower offers comprehensive OEM and ODM customization services for airframe developers and enterprise operators worldwide. Customization options include heavy-duty copper wire gauges, anti-spark industrial connectors (e.g., AS150U, XT90-S, QS8-S, Anderson), intelligent CAN-bus / SMBus BMS telemetry protocols, customized labeling, and reinforced carbon/aluminum protective outer casing.
