DALY BMS Li-ion 20S 72V 40A BMS Battery Management System for 18650 Battery Pack Balanced Charging Board

Description

Introduction TO DALY BMS 20S 72V 40A

The DALY BMS 20S 72V 40A is a reliable solution built to manage lithium-ion battery packs efficiently and safely. As power systems become more complex, managing each battery cell becomes crucial. This BMS supports 18650 lithium-ion cells arranged in a 20S configuration, making it suitable for 72V applications. Moreover, it’s widely used in electric bikes, energy storage systems, and IoT-based energy platforms. Because it includes multiple safety and balancing features, it helps ensure long-lasting battery performance.

Key features

To start with, this BMS supports a 20S (72V) configuration and delivers a continuous current of up to 40A. Additionally, it features passive cell balancing to maintain equal voltage across all cells, reducing the risk of imbalance. The board protects the battery from overcharging, over-discharging, short circuits, and overheating. Furthermore, some versions offer communication options like UART or CAN for real-time monitoring. Due to its efficient layout and durable construction, it is ideal for medium to high-load applications.
