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

DALY’s intelligent algorithms ensure accurate threshold controls to protect your batteries in all conditions.

Industrial-Grade Build

The BMS features a blue anodized aluminum casing that acts as a heat sink, providing passive cooling, structural rigidity, and resistance to dust and corrosion—ideal for harsh environments.

Applications

• Home Solar & Inverter Systems
• Electric Bicycles & Scooters
• Industrial Battery Packs
• DIY Lithium Battery Banks
• Portable Power Units & Camping Systems

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.
