103450 3.7V 1800mAh Li-Polymer Battery Features
Popular Soft-Pack Size
The 103450 1800mAh LiPo battery is a commonly used soft-pack cell for replacement batteries, custom battery packs, and compact portable electronics.
Reliable 3.7V Power Output
This battery has a nominal voltage of 3.7V, a full-charge voltage of 4.2V, and a typical capacity of 1800mAh. It is suitable for low- to medium-power electronic devices.
Compact 103450 Design
The model number "103450" refers to the cell size: about 10mm thick, 34mm wide, and 50mm long. With a protection board, wires, or connector, the total length may be around 51–52mm.
Mature and Easy to Source
Since this is a common and mature battery model, it usually does not require new tooling. Some stock may be available, which helps shorten lead time and support faster production.
Applications of 1800mAh 103450 Lithium Polymer Battery
The 1800mAh 103450 lithium polymer battery is suitable for compact electronic devices that require a slim battery size, stable voltage output, and low-to-medium current consumption. It is typically used in single-cell lithium battery systems with a nominal voltage of 3.7V and a full-charge voltage of 4.2V. The actual operating current should match the device power demand and the battery's protection board specification.
- Tracking and Monitoring Devices
- Recording and Communication Devices
- Small Consumer Electronics
- Not Recommended for High-Power Devices
Generally not suitable for mobile phones, tablets, drones, power tools, or other high-current devices.
Buying Tips
Check the voltage.
This is a single-cell lithium battery: 3.7V nominal, 4.2V fully charged. Devices using 7.4V or other voltages may need a custom series/parallel battery pack.
Check the size.
The bare 103450 cell is about 10 × 34 × 50mm. With a protection board, wires, or connector, it may be slightly longer.
Check the connector and polarity.
The same 2-pin connector may still have reversed positive and negative wires. Always confirm polarity before use.
Check protection and discharge current.
We recommend a battery pack with overcharge, over-discharge, over-current, and short-circuit protection. A 103450 1800mAh cell is typically around 1C / 1.8A max, suitable for small to medium-power devices, not high-current motor products.
