Daly smart bms
As we covered earlier, there are two completely different types of BMS units, the 3S and 4S style, and then 5S and up models. The 5s and up models do not use the same computer software as the 3S & 4S units.
For the 3S and 4S units, you need the Sinowealth BMS tool. If you have connected your BMS with the USB-UART cable, you may also need to install the drivers that are included in the Sinowealth BMS tool package. Our .ZIP file also includes a readme with full instructions for installation.
