Key Features

100% Smart Active Balancing

This BMS uses DALY's proprietary technology to actively balance each cell during charge and discharge cycles, helping to maximize the energy output and lifespan of the battery pack.

High Current Handling (100A)

Engineered to support continuous discharge and charge currents of 100A, it is ideal for demanding applications such as e-bikes, e-scooters, energy storage, and DIY battery builds.

Safety at its Core

The system is equipped with multiple protections:

• Overcharge/Over-discharge Protection
• Overcurrent Protection
• Short Circuit Protection
• Temperature Monitoring

UART & CAN Communication

Provides support for smart monitoring and control through UART and CAN interfaces, enabling real-time diagnostics and integration into intelligent battery systems.

Rugged and Durable Build

Its anodized aluminum casing not only provides superior heat dissipation but also ensures mechanical robustness and long-term reliability.

Applications

• Electric Scooters & Motorcycles
• E-Bikes & Light EVs
• Solar and Home Energy Storage Systems
• DIY Battery Banks / Powerwalls
• Industrial Automation and Robotics

Due to the battery capacity, internal resistance, voltage and other parameter values are not completely consistent, this difference causes the battery with the minimum capacity to be easily overcharged and discharged during charging, and the smallest battery capacity becomes smaller after damage, entering a vicious cycle. The performance of single cell directly affects the charge and discharge characteristics of the whole battery and the deduction of battery capacity. BMS lack of balance function is only a data collector, which is hardly a management system. The active equalization function can realize the maximum continuous 1A equalization current. Transferthe high-energy single cell to the low-energy cell, or use the whole group of energy to supplement the lowest single cell. During the implementation process, the energy is redistributed through the energy storage link, so as to ensure the battery consistency to the greatest extent, improve the battery mileage and extend the battery life.
