ASOL 604040 Lithium Polymer Battery — An ultra-slim 1100mAh soft-pack Lithium Polymer delivering 4.07Wh energy with 1.1A (1C) max discharge in an exceptional 6mm ultra-slim profile and 40×42mm near-square footprint.
Key advantages at a glance:
- 1100mAh capacity — outperforms most 6mm-thin batteries (typically lower capacity)
- 6mm ultra-slim — 25-40% thinner than standard 1100mAh batteries (8-10mm)
- 1.1A discharge — strong enough to drive small DC motors, RC cars, and robots
- 40×42mm near-square — maximizes internal space utilization in compact enclosures
Engineered for RC toys, programmable robots, STEM educational devices, handheld fans, mini printers, smart wearables, and wireless camera motors.
Why 6mm Ultra-Slim + 1100mAh — Comparison
| Battery Type | Capacity | Thickness | Footprint | Discharge | Best For |
|---|---|---|---|---|---|
| Standard 1100mAh | 1100mAh | 8~10mm | 35×45mm | 1C | Standard devices |
| ASOL 604040 | 1100mAh | 6mm | 40×42mm | 1C | Slim motor-driven devices |
| Standard 800mAh | 800mAh | 5~6mm | 30×35mm | 0.5C | Less capacity |
| Standard 1500mAh | 1500mAh | 10~12mm | 40×50mm | 1C | Too thick for slim devices |
Most 1100mAh batteries are 8~10mm thick. The 604040 delivers 1100mAh at 6mm — 25-40% thinner than competitors — while maintaining full 1C (1100mA) discharge to power small DC motors. The near-square 40×42mm footprint is ideal for compact RC toy and robot enclosures.
