The ITL0030100039-01 is a high-quality 3-series (3S) Battery Management System (BMS) designed to provide essential safety and management for 11.1V lithium-ion and lithium-polymer battery packs. With a maximum continuous discharge current of 8A, this compact and efficient protection board is the perfect solution for a wide range of low to medium-power applications, ensuring both battery longevity and operational safety.

This BMS integrates core protection features with reliable passive balancing, offering a cost-effective and dependable power management solution for DIY projects, consumer electronics, and commercial products.

 

Key Features & Benefits:

• Comprehensive Protection Suite: Safeguards your battery pack with multiple layers of critical protection:

  • Over-Charge Protection: Prevents any cell from exceeding its safe voltage limit during charging.

  • Over-Discharge Protection: Disconnects the load to avoid damaging deep discharges, preserving battery health.

  • Over-Current Protection (OCP): Protects the battery and connected device from damage due to excessive current draw.

  • Short-Circuit Protection: Provides instantaneous shutdown in case of a short circuit for ultimate safety.

• Integrated Cell Balancing: Features passive balancing circuitry that equalizes the voltage across all three cells during the charging process. This ensures each cell charges to its full capacity, maximizes the overall pack lifespan, and maintains consistent performance.

• Compact and Lightweight Design: Its small form factor makes it easy to integrate into space-constrained applications without compromising on performance or safety. 

• Optimized for 3S Configuration: Precisely calibrated for 3-series battery chains, managing a nominal voltage of 11.1V and a full charge voltage of 12.6V.

 

Primary Applications:

This versatile 3S BMS is an ideal choice for powering:

 

• Portable Electronics: DIY power banks, LED lighting systems, portable speakers.

• RC Hobby & Toys: Drones (UAVs), remote-controlled cars and boats.

• Portable Tools: Small electric tools, gardening equipment.

• Backup Power: Emergency lighting, small UPS systems.

• Robotics and IoT Devices.
