The DALY 100 BMS is a smart battery management system with built-in active balancing, supporting 4s-24s configurations and currents up to 500A. It optimizes performance for Li-ion, LiFePO4, and LTO batteries via Bluetooth monitoring, cell voltage balancing, and safety protocols like overcharge/over-discharge protection. Its modular design ensures scalability for industrial, solar, and EV applications.

How Does Built-In Active Balance Enhance Battery Performance?
The DALY 100 BMS uses active balancing to redistribute energy between cells, minimizing voltage gaps during charging/discharging. Unlike passive balancing (which wastes excess energy as heat), this method improves efficiency by 15-20%, extends cycle life by 30%, and ensures uniform cell aging. It’s critical for high-stakes applications like electric vehicles and grid storage, where cell consistency impacts safety and longevity.
Active balancing operates by transferring energy from higher-voltage cells to lower-voltage ones using inductor-based circuits. This process reduces thermal stress and minimizes energy loss compared to traditional resistor-based systems. For example, in a 24s LiFePO4 battery pack, the DALY 100 can balance cells at 1.2A per cycle, achieving voltage parity within 90 minutes during fast charging. This capability is particularly valuable in solar energy storage, where partial shading can create uneven cell degradation. Field tests show that systems using active balancing maintain 95% capacity after 2,000 cycles, versus 78% for passively balanced counterparts.

What Safety Features Does the DALY 100 BMS Offer?
The system includes over-voltage, under-voltage, over-temperature, and short-circuit protection. It automatically disconnects the load if voltages exceed 3.65V (LiFePO4) or 4.25V (Li-ion), or drop below 2.5V. Temperature thresholds are customizable via Bluetooth, with a default cutoff at 65°C. These features prevent thermal runaway, a common cause of battery fires, making it compliant with UN38.3 and IEC 62133 standards.
What Maintenance Is Required for Optimal Performance of Battery Systems? – Youth Battery
The DALY 100 employs a multi-layered safety architecture. Its MOSFET-based disconnect system reacts to faults in under 50 milliseconds, far faster than mechanical relays. The temperature monitoring uses three redundant sensors per module, detecting hotspots even in large battery arrays. For industrial users, the BMS logs all fault events with timestamps, aiding root cause analysis. A unique feature is its adaptive short-circuit response: it distinguishes between temporary surges (e.g., motor startups) and genuine faults, reducing false triggers by 60% compared to static threshold systems.
| Protection Type | Activation Threshold | Response Time |
|---|---|---|
| Over-Voltage | +0.05V above chemistry limit | <100ms |
| Under-Voltage | 2.3V (adjustable) | <200ms |
| Over-Temperature | 65°C (default) | <5 seconds |
Why Choose DALY 100 BMS for 8s-24s Battery Configurations?
Its modular architecture allows daisy-chaining up to 24 cells, ideal for high-voltage systems like solar farms or electric trucks. The BMS supports dynamic current adjustment: 300A models handle continuous loads, while 500A versions manage peak surges. Bluetooth integration enables real-time monitoring of individual cell voltages (±0.005V accuracy) and SOC calculations, critical for maintaining 48V/72V industrial battery banks.
How to Install the DALY 100 BMS with Bluetooth Monitoring?
Installation requires connecting sense wires to each cell’s positive terminal, ensuring polarity matches the labeled ports. Use 35mm² cables for 200A+ models. Pair the BMS via the Daly Smart BMS app (iOS/Android) to configure balancing thresholds, alarm limits, and firmware updates. Always isolate the battery during setup to avoid backfeeding. Calibration takes 2-3 full charge cycles for accurate SOC readings.
Can the DALY 100 BMS Work with LTO Batteries?
Yes. The BMS adjusts voltage limits for lithium titanate (LTO) chemistry, which operates at 1.5-2.8V per cell. Custom profiles in the app accommodate LTO’s unique charge curves, enabling precise balancing despite its flat discharge plateau. This flexibility makes it suitable for ultra-fast charging applications like EV buses, where LTO’s 10,000+ cycle lifespan outperforms conventional chemistries.
What Are the Cost Benefits of Using DALY 100 BMS?
By extending battery life by 30-40%, the BMS reduces replacement costs. For a 100kWh LiFePO4 system, this translates to $8,000+ savings over 10 years. Active balancing cuts energy waste by 18%, lowering operational expenses. Its fail-safe protections also minimize downtime in commercial setups, where a single shutdown can cost $5,000/hour in lost productivity.
The total cost of ownership analysis reveals even greater savings. A typical 200Ah 48V battery bank with DALY BMS achieves 4,000 cycles at 80% depth of discharge, versus 2,800 cycles without. For fleet operators with 50 EVs, this difference translates to delaying a $500,000 battery replacement by 3-4 years. Additionally, the system’s energy recovery during balancing saves 1.2kWh daily in a 100kW solar array—enough to power 40 LED streetlights overnight.
| Cost Factor | Standard BMS | DALY 100 BMS |
|---|---|---|
| Cycle Life | 2,500 cycles | 3,800 cycles |
| Energy Waste | 8% | 2.5% |
| Downtime Events | 3/year | 0.5/year |
