Installation Instructions
The power ranges described apply to the following products:
Massager battery pack, LED light backup power supply, 12V electronics, solar street light battery pack, monitoring backup power supply, and other products. Reminder: When assembling the battery pack, the battery voltage, capacity and internal resistance should be well matched. The battery voltage should be around the rated voltage of 3.7V. There is no output after the battery pack is assembled, and it can be charged with 8.4V voltage.
