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

Overview:
The 10S 20A JLGW Li-ion BMS is designed to protect and manage 10-series lithium-ion battery packs with a continuous discharge current of 20 amps. It provides comprehensive protection and cell balancing to ensure battery safety, performance, and longevity.

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: Approximately 2.8 V per cell (over-discharge protection)

• Continuous Discharge Current: 20 A

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

• Short Circuit Protection: Immediate shutdown with microseconds response time

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

• Quiescent (Idle) Current: Very low, in 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 protection (on some models)

• Communication: Some models may include UART or Bluetooth monitoring capabilities

Additional Features:

• Configurable Parameters: Many JLGW BMS units allow adjustment of protection thresholds and balancing settings via software or Bluetooth interface.

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

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

Applications:
Ideal for electric vehicles, e-bikes, energy storage systems, power tools, and other 10S Li-ion battery applications requiring reliable management at 20A continuous current.
