Description

 

Introduction to DALY 24V 40A BMS

The DALY 24V 40A BMS is a high-performance Battery Management System designed specifically for 7S Li-ion battery packs, including those using 18650 cells. As energy systems become more portable and versatile, the need for efficient, safe, and intelligent battery management increases significantly. Therefore, this BMS provides a reliable solution that combines core protection functions with IoT-ready communication options. Whether you’re working with e-bikes, solar backup units, or DIY power stations, this compact and smart BMS helps extend battery life while improving overall system stability.

Key features of DALY 24V 40A BMS

To begin with, this BMS offers active cell balancing to maintain voltage consistency across all seven cells, which greatly reduces degradation over time. Additionally, it includes full protection features such as overcharge, over-discharge, short circuit, and overcurrent safeguards. Furthermore, it is equipped with temperature sensors to prevent overheating. As a major advantage, it also supports communication through UART, RS485, or CAN interfaces, depending on the model. Consequently, users can integrate the BMS into smart systems for remote monitoring and control, enabling better management of energy usage and performance.
