The DALY Smart BMS is an intelligent protective board for LiFePO4 lithium batteries configured in series from 4 to 8 cells. It handles a continuous charging and discharging current of 40 A and a peak discharging current of up to 60 A. With support for 4S-8S LiFePO4 batteries, it is suitable for building and maintaining your own batteries. You can wirelessly monitor the status of the battery and individual cells via Bluetooth in a mobile application. The board measures cell voltages within the range of 1.5 to 4.5 V and operates at a voltage above 10 V.
The built-in active balancing with a current of 1 A equalises the voltage of individual cells and increases the usable capacity and lifespan of the entire battery. In addition to Bluetooth, the board also offers communication via RS485 and CAN for connection to inverters and superior systems. The Smart BMS automatically manages charging and discharging and protects individual cells from overcharging, deep discharging, and short circuits. Wireless management through the mobile application allows for convenient monitoring of voltage, current, and charge status at any time.
