Application Guide
18650 4S2P Battery Pack Integration for OEM Equipment
This 14.6V 5000mAh 18650 battery pack uses a 4S2P configuration. Four cells in series determine the pack voltage, while two parallel cell paths provide the combined capacity and contribute to current capability. For OEM integration, the BMS, connector, wiring and pack layout should be evaluated together with the enclosure space and load requirements.
Typical Applications
- OEM equipment requiring a 14.6V cylindrical battery pack
- Custom applications with a compatible electrical load
- Rechargeable equipment designed around a 4S layout
- Projects with confirmed enclosure and wiring requirements
Custom Battery Options
- BMS matched to continuous and peak current requirements
- Connector type, pinout and wiring configuration
- Pack layout based on available enclosure space
- Integration review including thermal considerations
Manufacturer / OEM
Electrical and Mechanical Information for 4S2P Integration
Provide the continuous current, peak current and peak duration, available enclosure space, connector, wiring requirements and application conditions. These inputs allow the BMS, pack layout and thermal considerations to be reviewed against the OEM equipment without changing the confirmed 14.6V 5000mAh configuration.
