The ASOL122640-2P is a premium Lithium Polymer battery pack using two flat 122640 soft pouch cells in a 2P parallel configuration, delivering a stable 3.7V nominal voltage and 2400mAh capacity (8.88Wh). The 122640 Lithium Polymer cell format (T12 × W26 × L40 mm per cell) provides an outstanding balance of energy density, slim profile, and compact footprint — the preferred choice for space-constrained smart and IoT devices where a thin, lightweight power source and dependable runtime are essential.
3.7V single-cell-voltage is the most widely adopted standard across smart-home, security, and portable consumer electronics. With 2400mAh capacity in a parallel pair, the ASOL122640-2P delivers steady all-day runtime for low-drain devices: weeks of standby on a smart video doorbell, extended recording on a wireless security camera, and long reporting intervals on a GPS tracker. The compact 2P pouch construction keeps the host device slim and light, with stable ±1C output that protects sensitive electronics from voltage sag.
Each pack can be supplied with an optional PCM/PCB protection circuit guarding against over-charge, over-discharge, over-current, and short circuit — important for consumer and medical IoT safety. Inspection requirements and acceptance criteria are confirmed for each project before order release. Grade-A Lithium Polymer cells are voltage-matched within ±10mV to ensure stable parallel operation and uniform cycle aging.

Why Choose Lithium Polymer Over Cylindrical Li-ion Cells?
For smart-home, security, and portable IoT devices, the choice of battery format directly impacts product thickness, weight, and design freedom. Here is a side-by-side comparison:
| Feature | 122640-2P Lithium Polymer (This Product) | 18650 Li-ion |
|---|---|---|
| Weight | ~38g (ultra-light) | ~46g (single 18650) |
| Thickness | ~12mm per cell (slim) | ~18mm (round cell) |
| Form Factor | Flat — fits slim enclosures | Cylindrical — needs round holder |
| Shape Flexibility | Custom dimensions possible | Fixed 18×65mm cell size |
| Voltage | 3.7V nominal (single-cell) | 3.6-3.7V nominal |
| Capacity | 2400mAh (2P) | 2000-3500mAh |
| Discharge | Smooth 1C, low voltage sag | 1C-2C typical |
| Cycle Life | ≥500 cycles | ≥500 cycles |
| Design Advantage | Thin, light, custom-shaped | Bulkier round profile |
Choose 122640-2P Lithium Polymer when: A slim profile, light weight, custom form factor, and smooth low-drain output matter most — ideal for smart doorbells, security cameras, GPS trackers, POS terminals and medical IoT.
Choose 18650 Li-ion when: A rigid cylindrical cell is acceptable and maximum single-cell capacity in a round form factor is the priority.

What certifications does the ASOL122640-2P 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 122640 Lithium Polymer cell?
122640 refers to the cell's physical dimensions: approximately 12mm thick × 26mm wide × 40mm long. This is a soft pouch Lithium Polymer format that provides a slim, lightweight energy source — ideal for smart doorbells, security cameras, GPS trackers and other compact IoT devices where space and weight matter.
How does 122640-2P Lithium Polymer compare with an 18650 Li-ion cell for IoT devices?
The 122640-2P Lithium Polymer is a thin, flat pouch pack that fits slim enclosures, whereas an 18650 is a rigid cylindrical cell that needs a round holder. The 2P pouch is lighter, easier to integrate into compact products, and can be built to custom dimensions. Choose 122640-2P Lithium Polymer when a slim profile, light weight and custom shape matter; choose an 18650 when a rigid cylindrical cell with maximum single-cell capacity is acceptable.
