7S 10A SLCT Li-ion Battery Management System (BMS)

Overview:
This 7S 10A SLCT Li-ion BMS is designed for 7-series lithium-ion battery packs with a continuous discharge current rating of 10 amps. It offers protection, balancing, and safe operation for your Li-ion battery pack.

Key Specifications:

• Battery Configuration: 7 cells in series (7S)

• Nominal Voltage: ~25.9 V (3.7 V per cell × 7)

• Maximum Charge Voltage: 29.4 V (4.2 V per cell max)

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

• Continuous Discharge Current: 10 A

• Peak/Overcurrent Protection: Typically triggers at around 15–20 A

• Short Circuit Protection: Instant shutoff (microseconds response time)

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

• Quiescent (Idle) Current: Ultra-low microampere range

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

• Physical Dimensions: Typically smaller than 20A versions; varies by model

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

Additional Features:

• Selectable Settings (SLCT): Adjustable parameters for overcurrent and balancing thresholds available in some models.

• Chemistry Compatibility: Optimized for Lithium-ion (Li-ion) and NMC cells; settings may vary for other chemistries.

• Port Design: Available in single or multi-port versions depending on the model.

Applications:
Best suited for smaller capacity devices such as electric bikes, portable power tools, small solar storage, and other low-to-moderate power Li-ion battery packs.
