DALY BMS Li-ion 20S 72V 60A BMS Battery Management System for 18650 Battery Pack Balanced Charging Board

Description

 

Introduction

The 20S 72V battery BMS delivers high performance for managing large lithium-ion battery packs. It works seamlessly with 18650-based 72V systems and protects batteries from overcharge, over-discharge, and thermal issues. As IoT and electric power systems grow in scale, users increasingly prioritize safe energy management. This BMS ensures smooth and secure operation even under heavy loads. Engineers commonly use it in electric bikes, solar setups, industrial IoT systems, and energy storage projects.

Key features OF 20S 72V battery BMS

To begin with, the BMS supports a 20S configuration, delivering a nominal 72V system voltage. It handles a continuous discharge current of 60A, making it ideal for medium to high-power use. Moreover, it includes passive cell balancing, which maintains even voltages across all cells. The board offers essential protections including over-voltage, under-voltage, overcurrent, short circuit, and temperature cutoffs. In addition, it may feature smart communication interfaces such as UART, CAN, or RS485 for real-time monitoring. As a result, it is highly suitable for both connected and standalone systems.
