Product Details
The 44.4V 12S 32000mAh High-Power Agricultural & Heavy-Lift UAV LiPo Battery Pack is an industrial-grade, high-discharge Lithium Polymer (LiPo) battery pack engineered specifically for commercial 12S agricultural multicopters, firefighting UAVs, and extreme payload delivery drones. Delivering 44.4V nominal voltage and a rated capacity of 32000mAh (32Ah) (1420.8Wh) with a continuous discharge capability of 25°C (pulse up to 50C), it provides exceptional power density, ultralow internal resistance (ΔIR ≤ 0.5mΩ), and rigorous cell consistency matching. Built inside a Integrated Impact-Resistant ABS Shell with Ergonomic Carrying Handle with genuine Heavy-Duty Quick-Release High-Amperage Plug / Dual AS150U connectors, this pack meets international UN38.3, MSDS, and CE compliance. For comprehensive sizing principles, consult our Heavy-Lift Drone Battery Systems: Sizing 14S to 24S High-Voltage Packs. Before deployment or fleet integration, verify battery tray dimensions (260 × 185 × 120 mm (±2mm)), charger cutoff voltage (50.4V), and peak ESC motor current requirements.

UAV System Compatibility & Engineering Fit Check
To ensure optimal aerodynamic stability, power transfer efficiency, and onboard electronic speed controller (ESC) longevity, verify the following baseline hardware requirements. For comparative analysis, review our Agricultural Drone Batteries: Voltage, Capacity and C-Rate Guide:
- Payload & Compartment Clearances: Ensure the UAV battery tray accommodates external dimensions of 260 × 185 × 120 mm (±2mm) with at least 8–10mm buffer allowance for lead clearance and cooling airflow.
- ESC & Continuous Amperage Matching: The propulsion system must be calibrated for 44.4V input, capable of drawing 800A continuous and sustaining 1600A peak burst current without voltage sag below 36V.
- Connector Polarity & Anti-Spark Protection: Fitted with genuine Heavy-Duty Quick-Release High-Amperage Plug / Dual AS150U terminals. For high-voltage systems (≥6S/8S/12S), anti-spark spark-suppressing connectors are pre-installed to prevent terminal erosion during hot-plugging.
- Charger Profile Calibration: Use intelligent multi-chemistry balance chargers programmed strictly for Lithium Polymer (LiPo) charging parameters with cutoff precision within ±0.02V per cell.
First-Party Engineering & Cell Grading Evidence
GEB enforces stringent automotive-grade manufacturing protocols to ensure mission-critical flight safety across commercial operations:
Every cell undergoes automated capacity grading and high-precision laser sorting. Cell-to-cell capacity variance is kept within ΔC ≤ 1.0%, and internal resistance within ΔIR ≤ 0.5mΩ.
Thickened pure copper and nickel-plated collector plates are ultrasonically bonded directly to tabs, eliminating hot spots and minimizing total internal pack impedance under heavy load.
Reinforced composite housing and thermal conduction interlayers facilitate uniform core-to-surface heat transfer, mitigating cell degradation during multi-cycle continuous flights.
Operating Environmental Boundaries & Safety Limits
| Parameter | Permissible Safe Operating Range | Critical Threshold / Precaution |
|---|---|---|
| Discharge Temperature | -10°C to +60°C (14°F to 140°F) | Preheat pack to ≥15°C in subzero climates before takeoff |
| Charge Temperature | 0°C to +45°C (32°F to 113°F) | Never charge cold or frozen cells below 0°C (risk of lithium plating) |
| Storage State (Long-term) | +15°C to +25°C, 45%–65% RH | Store at 3.80V–3.85V per cell nominal storage state (~50% SoC) |
| Maximum Safe Discharge Cutoff | 36V (Overall Pack) | Do not discharge past 3.0V/cell under load to prevent irreversible degradation |
