Application Guide

18650 1S8P Battery Pack Integration

This product is a 3.7V 20800mAh cylindrical lithium-ion battery pack made with 18650 cells in a confirmed 1S8P configuration. One series group sets the nominal pack voltage, while eight parallel cell paths provide the confirmed combined capacity. Pack layout and integration should be reviewed against the host product's available installation space and electrical requirements.

Typical Applications

  • Storage products with compatible electrical requirements
  • Solar products designed for a 3.7V battery pack
  • OEM projects with space for the confirmed 1S8P layout

Custom Battery Options

  • Pack layout based on available installation space
  • Protection requirements to be confirmed for the project
  • Connector and wiring requirements to be confirmed
  • Integration review for the host product
