4S 10A SLCT Li-ion Battery Management System (BMS)

Overview:
The 4S 10A SLCT Li-ion BMS is designed for lithium-ion battery packs configured in 4 cells in series. It provides a continuous discharge current of 10 amps and includes protection features that ensure battery safety, efficiency, and balanced operation.

Key Specifications:

• Battery Configuration: 4 cells in series (4S)

• Nominal Voltage: ~14.8 V (3.7 V per cell × 4)

• Maximum Charge Voltage: 16.8 V (4.2 V per cell max)

• Discharge Cutoff Voltage: ~2.8 V per cell (≈11.2 V total)

• Continuous Discharge Current: 10 A

• Overcurrent Protection: Typically activates at 15–20 A

• Short Circuit Protection: Yes, with automatic recovery (depending on model)

• Cell Balancing: Passive balancing with 30–60 mA per cell

• Quiescent Current: Ultra-low current drain in standby mode

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

• Dimensions: Compact size, varies slightly by model

• Protection Features:

  • Overcharge protection

  • Over-discharge protection

  • Overcurrent and short circuit protection

  • Passive cell balancing

  • Optional temperature protection

Additional Features:

• SLCT Technology: Some parameters (like overcurrent trip point or balancing voltage) may be adjustable depending on model.

• Battery Chemistry Compatibility: Designed for Lithium-ion (Li-ion) and NMC battery types.

• Port Configuration: Available in both single-port (common charge/discharge) and dual-port models.

Applications:
Ideal for smaller battery-powered systems such as:

• DIY battery packs

• E-scooters and e-bikes (small-scale)

• LED lighting systems

• Power banks and backup systems

• RC applications or portable electronics
