3.6V 37.5Ah ultra-thin high energy density drone battery cell (AS-6497T6) delivering 350Wh/kg at just 6.7mm thickness and 380g. The ultra-thin large-area form factor is ideal for flying wing and blended-wing-body UAVs where cells must fit inside thin wing profiles. Features 3C continuous discharge (112.5A), ≤2.5mΩ internal resistance, and 300-cycle life. Perfect for long-range survey, solar HALE, VTOL fixed-wing, and high-altitude long-endurance drone platforms. OEM/ODM custom pack assembly available.
Description
Model AS-6497T6 – 3.6V 37.5Ah Ultra-Thin High Energy Density Drone Battery Cell
Voltage: 3.6V | Capacity: 37.5Ah (135Wh) | Energy Density: 350Wh/kg | Thickness: 6.7mm | Size: 266 x 97mm | Weight: 380g
The AS-6497T6 is a 3.6V 37.5Ah ultra-thin high energy density drone battery cell engineered for flying wing, blended-wing-body, and solar HALE UAV platforms where cell thickness is the critical design constraint. At just 6.7mm thick with a large 266 x 97mm footprint, this flat pouch cell fits perfectly inside thin wing profiles and blended wing structures where conventional thick cells cannot be used.
Delivering 350Wh/kg gravimetric energy density at only 380g, the AS-6497T6 maximizes range and endurance without adding weight. With ≤2.5mΩ internal resistance, it supports 3C continuous discharge (112.5A) and 5C peak discharge (187.5A) — stable output for efficient cruising and VTOL transition. The wide 25mm tabs ensure efficient current transfer. Rated for 300 cycles and operating across -20°C to +60°C discharge, this cell is ideal for building custom high-voltage drone packs for flying wing, solar HALE, long-range survey, and VTOL fixed-wing platforms.

Why 6.7mm Ultra-Thin Design Matters
Most drone LiPo cells are 10~12mm thick, making them impossible to fit inside thin flying-wing profiles or blended-wing-body structures. The AS-6497T6 is just 6.7mm thick — 40% thinner than conventional cells — with a large flat footprint that lays perfectly inside wing sections. This enables entirely new UAV designs where the battery becomes a structural element of the wing.
| Standard Drone LiPo Cell | ~10.5mm thick |
| High-Density Drone Cell (A488J9) | 10.4mm thick |
| AS-6497T6 Ultra-Thin | 6.7mm thick (-36%~-57%) |
Core Advantages
- ✔
Ultra-Thin 6.7mm Form Factor: At just 6.7mm thick, this cell fits inside thin flying-wing profiles and blended-wing-body structures where conventional 10~12mm cells cannot — enabling aerodynamically efficient UAV designs. - ✔
High Energy Density: Delivers 350Wh/kg — up to 59% more energy per gram than standard drone LiPo cells (~220Wh/kg) — maximizing endurance for long-range and high-altitude missions. - ✔
Large-Area Flat Pouch: The 266 x 97mm footprint lays flat inside wing sections, distributing weight evenly across the wingspan and improving structural balance — ideal for flying wing and solar UAV integration. - ✔
Stable Power Output: ≤2.5mΩ internal resistance with 3C continuous (112.5A) and 5C peak (187.5A) discharge — reliable power for efficient cruising and VTOL transition phases. - ✔
Wide Temperature Operation: Discharges reliably from -20°C to +60°C — suitable for high-altitude, cold-climate, and stratospheric platforms where standard cells suffer voltage sag.
