10S 20A Daly Li-ion Battery Management System (BMS)

Overview:
The 10S 20A Daly Li-ion BMS with PWM is designed for 10-series lithium-ion battery packs, supporting continuous discharge currents of up to 20 amps. Featuring Pulse Width Modulation (PWM) technology, this BMS enhances charging and discharging efficiency, improves thermal management, and extends battery lifespan.

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: 20 A

• Peak/Overcurrent Protection: Usually activates between 30–40 A

• Short Circuit Protection: Instant shutdown within microseconds

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

• PWM Control: Uses Pulse Width Modulation to regulate charging/discharging, improving efficiency and reducing heat

• Quiescent Current: Very low, in microampere range

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

• Physical Dimensions: Compact and model-dependent

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

Additional Features:

• PWM Technology: Optimizes power delivery through pulse modulation, reducing stress on components and enhancing battery life.

• Selectable Settings: Some Daly BMS models allow configuration of protection parameters and balancing settings.

• Chemistry Compatibility: Designed for Lithium-ion (Li-ion) and NMC batteries.

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

Applications:
Ideal for electric vehicles, e-bikes, solar storage systems, power tools, and other battery-powered devices requiring efficient management of 10S Li-ion battery packs at 20A continuous current
