10S 20A TDT Li-ion Battery Management System (BMS) with Cell Balancing

Overview:
The 10S 20A TDT Li-ion BMS is designed for 10-series lithium-ion battery packs, providing a continuous discharge current of 20 amps. Featuring cell balancing and advanced protection features, this BMS ensures battery safety, longevity, and optimal performance.

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: Typically activates at 30–40 A

• Short Circuit Protection: Instant shutdown with microseconds response time

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

• Quiescent (Idle) Current: Very low, in microampere range

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

• Physical Dimensions: Model dependent, generally compact

• Protection Features: Overcharge, over-discharge, overcurrent, short circuit, cell balancing, optional temperature monitoring

Additional Features:

• TDT Technology: Enhanced thermal dissipation and efficiency for high current operations.

• Selectable Settings: Some models offer configurable parameters for overcurrent and balancing.

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

• Port Design: Available with single or multiple ports depending on model.

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