The DALY 100 BMS is a smart battery management system designed for Li-ion, LiFePO4, and LTO batteries. It features active balancing, Bluetooth monitoring, and supports configurations from 4s-8s to 8s-24s with current ratings up to 500A. Its robust design ensures optimal performance, safety, and longevity for high-demand applications like EVs and solar storage.

How Does Active Balance Technology Improve Battery Efficiency?
The DALY 100 BMS uses active balancing to redistribute energy between cells, minimizing voltage gaps and preventing overcharging/over-discharging. This extends battery lifespan by up to 30% compared to passive balancing, especially in high-current applications like electric vehicles. Real-time adjustments ensure uniform cell performance, critical for maintaining capacity in multi-cell configurations.
Active balancing operates by transferring excess energy from higher-voltage cells to lower-voltage ones through inductors or capacitors, unlike passive systems that dissipate energy as heat. This method achieves 92-95% energy transfer efficiency, particularly beneficial in large battery packs where minor imbalances can compound over cycles. For example, in a 24s LiFePO4 setup, the BMS can balance cells at 2A per channel during both charging and discharging phases. Users report 18% longer runtime in solar storage applications after six months of use compared to conventional BMS units.
| Balancing Type | Energy Efficiency | Heat Generation | Optimal Use Case |
|---|---|---|---|
| Active | 92-95% | Low | High-current EV batteries |
| Passive | 60-70% | High | Low-cost consumer electronics |
What Safety Mechanisms Does the DALY 100 BMS Provide?
Key protections include over-voltage (±0.5% accuracy), under-voltage, over-current (response time <1ms), and short-circuit safeguards. The dual-layer PCB design isolates high-current pathways from control circuits, enhancing reliability. A temperature sensor array monitors cell conditions, triggering shutdowns if thresholds exceed -20°C to +85°C.
How Does the Daly Smart BMS Enhance Battery Management Systems?
The BMS employs three-tiered protection logic: primary software limits, hardware-based circuit breakers, and physical MOSFET disconnects. During thermal runaway scenarios, it activates cell-level fusing within 500μs while maintaining communication with external controllers. Field tests show 99.98% accuracy in over-current detection across 500+ charge cycles. For extreme environments, the optional titanium alloy casing provides EMI shielding up to 60dB, crucial for industrial robotics operating near arc welders or high-frequency machinery.
| Protection Type | Threshold Accuracy | Response Time | Recovery Method |
|---|---|---|---|
| Over-Voltage | ±0.5% | 15ms | Auto-reset after 2min |
| Under-Voltage | ±1% | 20ms | Manual reset required |
| Over-Current | ±3% | 0.8ms | Cool-down period |
Which Battery Chemistries Are Compatible with the DALY 100 BMS?
This BMS supports Li-ion (3.0-4.2V), LiFePO4 (2.5-3.65V), and LTO (1.5-2.8V) batteries. Its adaptive voltage thresholds automatically adjust for each chemistry, enabling seamless integration without manual recalibration. The system also detects faulty cells and triggers failsafes, making it versatile for hybrid energy storage systems.
Why Is Bluetooth Connectivity Critical for Battery Monitoring?
The integrated BT module allows real-time tracking of voltage, temperature, and SOC via the Daly Smart BMS app. Users receive alerts for anomalies like cell imbalances or overheating, enabling proactive maintenance. Remote parameter adjustments reduce downtime in industrial setups, while data logging aids in diagnosing performance trends over time.
How to Configure the BMS for 8s-24s Battery Packs?
For 8s-24s setups, connect balance leads sequentially from cell 1 to cell 24. Use the app’s “Series Configuration” mode to set the total count. The BMS auto-detects voltage ranges but verify polarity with a multimeter. Ensure all cells are pre-balanced (±50mV) before activation to avoid tripping protection circuits during initialization.
Can the DALY 100 BMS Handle 500A Continuous Discharge?
Yes, the 500A model uses graphene-enhanced MOSFETs with a 2mΩ on-resistance, reducing heat generation by 40% versus standard FETs. In stress tests, it sustained 550A for 15 minutes without derating. For peak loads, pair it with active cooling (e.g., heatsinks or fans) to maintain efficiency in climates above 35°C.
What Are the Maintenance Requirements for This BMS?
Inspect balance leads quarterly for corrosion or looseness. Calibrate voltage sensors annually via the app’s “Auto-Learn” function. Update firmware biannually to access new features like predictive failure analytics. For dusty environments, use compressed air to clean PCB vents, ensuring uninterrupted thermal regulation.
Expert Views: Industry Perspectives on the DALY 100 BMS
“The DALY 100’s active balancing is a game-changer for second-life EV batteries,” says Dr. Elena Torres, a renewable energy systems engineer. “Its ability to handle mixed chemistries in cascaded arrays allows recyclers to repurpose cells with up to 15% capacity variance—something most BMS units can’t manage without derating the entire pack.”
