Application Guide
2S4P 18650 Battery Pack Integration for OEM Equipment
This 7.4V 8000mAh 18650 battery pack uses a 2S4P configuration. Two cells in series determine the pack voltage, while four parallel cell paths increase the available capacity and support the current required by the host equipment. For OEM integration, the BMS, connector, cable length and pack layout can be matched to the electrical requirements and available installation space.
Typical Applications
- Custom battery integration for OEM equipment
- Power tools with a compatible voltage and load profile
- E-mobility equipment with a confirmed installation envelope
- Rechargeable devices requiring a 7.4V 2S pack
Custom Battery Options
- BMS matched to the required continuous and peak current
- Connector type and pinout for the host equipment
- Cable length, routing and termination
- Pack layout based on the available installation space
