Description
Model AS-A488J9 – 3.8V 36Ah High Energy Density Drone Battery Cell
Voltage: 3.8V | Capacity: 36Ah (136.8Wh) | Energy Density: 343Wh/kg | Size: 189 x 88 x 10.4mm | Weight: 383g
The AS-A488J9 is a 3.8V 36Ah high energy density drone battery cell engineered for long-endurance UAV platforms that prioritize maximum flight time and payload capacity. Delivering an exceptional 343Wh/kg gravimetric energy density at just 383g, this high-voltage lithium polymer pouch cell enables significantly longer endurance without adding weight to your drone.
With an ultra-low internal resistance of ≤2mΩ, the AS-A488J9 supports 3C continuous discharge (108A) and 5C peak discharge (180A) — providing stable output for cruising, hover, and moderate-load operations. The wide 25mm tabs ensure efficient current transfer with minimal heat buildup. Rated for 500 cycles and operating across -20°C to +60°C discharge, this cell is ideal for building custom 6S, 12S, and 14S drone battery packs for long-range survey, industrial inspection, VTOL, and delivery UAV platforms. It is also widely used in e-bike battery swap systems and electric garden tools.

Why 343Wh/kg Matters for Drones
Standard drone LiPo cells typically deliver 200~250 Wh/kg. The AS-A488J9 achieves 343 Wh/kg — up to 70% more energy per gram. For a 12S 36Ah drone pack, this means approximately 1.8kg less weight compared to conventional cells, translating directly to longer flight time or increased payload capacity.
| Standard Drone LiPo Cell | ~220 Wh/kg |
| High-Performance Drone LiPo | ~250 Wh/kg |
| AS-A488J9 High Energy Density (3.8V HV) | 343 Wh/kg (+37%~70%) |
Core Advantages
- ✔
Ultra-High Energy Density: At 343Wh/kg, the AS-A488J9 delivers up to 70% more energy per gram than standard drone LiPo cells — maximizing flight endurance and payload capacity for long-range missions. - ✔
High-Voltage 3.8V Platform: Nominal 3.8V (vs. standard 3.7V) means higher pack voltage at the same series count — a 12S pack delivers 45.6V nominal, boosting motor efficiency and top speed. - ✔
Low Resistance, Stable Output: Ultra-low ≤2mΩ internal resistance with 3C continuous (108A) and 5C peak (180A) discharge — reliable power for cruising, hover, and payload operations. - ✔
Wide Temperature Operation: Discharges reliably from -20°C to +60°C — suitable for high-altitude, cold-climate, and industrial drone operations where standard cells suffer voltage sag. - ✔
Custom Drone Pack Assembly: Single-cell format with 25mm wide tabs enables flexible series/parallel configurations — build 6S (22.8V), 12S (45.6V), 14S (53.2V) and higher voltage drone packs with BMS, connectors, and enclosure tailored to your platform.
