1. Introduction
The HS-P08 is a dual-series 7.4V lithium battery charging module designed based on the FM4258 boost charging management chip, using a Type-C interface 5V input, specifically used for charging a 2-series 18650 lithium battery pack.This module can be used to charge the lithium battery with a solar panel or data cable. When charging, the green charging indicator light will turn on to directly display the charging status. When the battery is fully charged, the green full charge indicator light will turn off, indicating that charging is complete.Supports multiple charging input methods, can accept DC input of 5-5.5V. Equipped with Type-C 5V charging port and has a USB charging 5V interface.It can provide various voltage outputs, including a 7.4V output interface, which can meet the needs of different electrical equipment.
