ASOL 103665 3.7V 3000mAh Lithium Polymer battery infographic — portable Bluetooth speakers, GPS trackers & POS terminals

ASOL 103665 Lithium Polymer Battery — A high-capacity 3000mAh soft-pack Lithium Polymer delivering 11.1Wh energy in a slim 10.5mm profile with an elongated 36×68mm rectangular footprint. The elongated form factor combined with high capacity makes it ideal for portable Bluetooth speakers, GPS trackers, handheld game consoles, POS terminals, and barcode scanners.


Why 103665 Form Factor — Shape Comparison

Battery Model Thickness Width Length Best For
ASOL 103665 10.5mm 36mm 68mm Elongated slim devices
ASOL 803040 8.0mm 30mm 42mm Standard compact devices
ASOL 102050 10.5mm 20mm 50mm Narrow elongated devices

The 103665’s 68mm length is ideal for devices with tall, narrow internal cavities — a common form factor for compact POS terminals, handheld scanners, and beauty devices. The 36mm width balances capacity with a moderate footprint.

Application and RFQ guide

How to specify ASOL 103665 3.7V 3000mAh Lithium Polymer Battery Cell for your project

This configuration is relevant to portable speakers, connected devices and compact consumer electronics. Treat the published table as a starting specification; final pack design should be confirmed against the actual load, charger, mechanical space and destination requirements.

Key engineering checks

Confirm runtime target, amplifier or radio load peaks, enclosure geometry, charge-current limit and connector layout before sampling. This gives the engineering team the information needed to assess the cell arrangement, protection circuit, wires and connector.

Questions for an RFQ

Share expected order quantity, dimensional drawing, target runtime, connector photo or pinout, charging method and any required test or shipping documentation. A project quotation can then be matched to the finished equipment rather than a generic pack.
