The ASOL605573 is a premium Li-ion battery pack using four flat 605573 soft-pouch cells in a 4S1P series configuration, delivering a stable 14.8V nominal voltage and 3000mAh capacity (44.4Wh). The 605573 Li-ion cell format (6mm thick x 55mm wide x 73mm long) provides a compact, lightweight form factor for applications where both power and portability matter.
14.8V is a common operating voltage for FPV drones and UAVs, robotics and mobile robot platforms, portable power modules, and light-duty cordless equipment. With 3000mAh capacity, the ASOL605573 can support 4S battery designs for drone builds, STEM robots, small AGVs, DC portable power modules, LED lighting packs, electric screwdrivers, small handheld drills and portable repair tools. Runtime depends on actual load current, BMS settings and connector choice.
Each pack incorporates a built-in PCB protection circuit (or optional full BMS with 4S cell balancing) guarding against overcharge, over-discharge, overcurrent and short circuit. Inspection requirements and acceptance criteria are confirmed for each project before order release. Grade-A Li-ion cells are voltage-matched within +/-10mV to support stable series operation and uniform cycle aging.

Why Choose Soft Pouch Cell Li-ion Over Cylindrical Cells?
For drones, power tools, and portable power applications, the choice of battery format directly impacts product performance and design flexibility. Here is a side-by-side comparison:
| Feature | 605573-4S Soft Pouch Cell Li-ion (This Product) | 18650-4S Li-ion |
|---|---|---|
| Thickness | ~20mm (ultra-thin) | ~36mm (4 cells side by side) |
| Weight | ~180g | ~240g |
| Shape | Flat — fits slim compartments | Cylindrical — needs round cell holders |
| Form Factor Flexibility | Custom dimensions possible | Fixed 18×65mm cell size |
| Internal Resistance | ≤20mΩ (Soft Pouch Cell design) | ~150-200mΩ |
| Capacity | 3000mAh | 2600-3500mAh (comparable) |
| Energy | 44.4Wh | 38.5–51.8Wh (comparable) |
| Cycle Life | ≥500 cycles | ≥500 cycles |
| Weight Advantage | 25-30% lighter | Heavier |
Choose 605573-4S when: Weight, thin profile, and form factor flexibility are critical — ideal for drones, slim power tools, and compact portable power.
Choose 18650-4S when: Maximum runtime and mature supply chain are priorities, and the larger cylindrical form factor is acceptable.

We support all standard RC, drone, and power tool connectors: XT60, XT90, EC5, JST-PH 2.0, JST-XH, Deans T-plug, Tamiya, Molex, and custom connectors. Balance charge connectors (JST-XH 5-pin) can be included for 4S balance charging with any standard Li-ion charger.
What certifications does the ASOL605573 have?
Certification and test-document requirements depend on the selected cell, pack configuration and destination market. Please confirm requirements during project review.
What is a 605573 Soft Pouch Cell Li-ion battery?
605573 refers to the cell's physical dimensions: 6mm thick × 55mm wide × 73mm long. This is a standard Soft Pouch Cell Li-ion format that enables flat, compact battery pack designs — ideal for drones, power tools, and portable power applications where space and weight are critical.
How does 605573-4S Soft Pouch Cell Li-ion compare with 18650-4S Li-ion for drones and power tools?
Soft-pouch and cylindrical cells use different geometries and available specifications. Final weight, size, runtime, discharge performance and thermal behavior depend on the selected cell model and complete pack design. Choose the format after reviewing the target enclosure, load profile and validation requirements.
