10S 30A Daly Li-ion Battery Management System (BMS)

Overview:
The 10S 30A Daly Li-ion BMS with PWM is designed to manage and protect 10-series lithium-ion battery packs, supporting continuous discharge currents up to 30 amps. Equipped with Pulse Width Modulation (PWM) technology, this BMS ensures efficient charging and discharging, optimal thermal management, and extended battery life.

Key Specifications:

• Battery Configuration: 10 cells in series (10S)

• Nominal Voltage: Approximately 37.0 V (3.7 V per cell × 10)

• Maximum Charge Voltage: 42.0 V (4.2 V per cell max)

• Discharge Cutoff Voltage: Around 2.8 V per cell (over-discharge protection)

• Continuous Discharge Current: 30 A

• Peak/Overcurrent Protection: Typically activates between 40–50 A

• Short Circuit Protection: Instant shutdown within microseconds

• Cell Balancing: Passive balancing with 30–80 mA per cell

• PWM Control: Utilizes Pulse Width Modulation for precise power regulation during charging/discharging, reducing heat and improving efficiency

• Quiescent Current: Very low microampere range

• Operating Temperature Range: -20°C to +60/65°C

• Physical Dimensions: Compact, model-dependent

• Protection Features: Overcharge, over-discharge, overcurrent, short circuit, cell balancing, temperature monitoring (depending on model)

Additional Features:

• PWM Technology: Enhances power management by modulating charge/discharge pulses, improving battery longevity and safety.

• Configurable Settings: Some Daly BMS units allow adjustment of protection parameters and balancing thresholds.

• Chemistry Compatibility: Optimized for Lithium-ion (Li-ion) and NMC battery chemistries.

• Port Design: Available with separate or combined charge/discharge ports depending on the model.

Applications:
Suitable for electric vehicles, e-bikes, portable power stations, solar energy storage, and other high-performance lithium-ion battery-powered systems requiring 10S configuration at 30A continuous current.
