I have a CALB (China Aviation Lithium Battery) 12V 4S3P 250Ah LiFePO4 battery. The battery is managed by a DALY 4S 12V 250A (R05W-FL07) Battery Management System (BMS).

In this video, I demonstrate how I install the Sinowealth BMS software on my WIN10 laptop. Then connect my laptop to the DALY BMS via a USB-to-UART communications cable.

This enabled the Sinowealth software to read data from the DALY BMS, and manage the configuration of BMS. I include steps on how to update firmware in the BMS.

I know I struggled at the start to ensure I was installing the software correctly, & also configuring properly so as not to damage the battery & BMS. The reason for the struggle is because the software installation instructions are in chinese. So perhaps this video will help a small group of people who DIY their LiFePO4 battery management.

This content is intended for Newbies starting out on their FUN journey to managing their LiFePO4 & BMS systems.
