ASOL 122640-2P 3.7V 2400mAh Lithium Polymer Battery Pack

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 a customizable 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.

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.

Yes. The ASOL122640-2P delivers a stable 3.7V nominal output with 2400mAh capacity, ideal for low-drain devices such as smart video doorbells, wireless security cameras, GPS trackers and other smart-home products. The slim 2P pouch design fits compact enclosures, and we can supply JST, Molex 2-pin or custom connectors to match your board.

What is the minimum order quantity (MOQ)?

MOQ is confirmed after specification review. Sample evaluation may be available for selected cylindrical and lithium polymer battery projects, subject to specification review and product availability. Sample freight is paid by the customer.

Can I use this battery in a portable medical device?

This battery configuration can be evaluated for portable medical and consumer IoT projects. Suitability must be verified against target-device electrical, mechanical, protection and project requirements. Existing CE, RoHS and UN38.3 documentation, plus MSDS safety documentation, can be reviewed for the selected configuration. NTC thermistor and protection-threshold requirements can be evaluated during project review.

What connector options are available?

We support common IoT and consumer connectors: JST-PH 2.0, JST-SH 1.0, Molex PicoBlade, Molex, board-to-board solder tabs, tinned wire leads, and fully custom connectors. We can also add an NTC thermistor lead for temperature monitoring.

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.
