SQ24 100A Smart BMS Advanced 24S Battery Protection System

 


As battery-powered systems grow larger and more sophisticated, the need for intelligent, high-current battery management has never been greater. Whether you’re building an energy storage system, designing an electric vehicle, or managing a high-voltage lithium-ion battery pack, one component stands at the core of safety and performance: the Battery Management System (BMS).

The SQ24 100A Smart BMS is a top-tier solution designed to manage and protect 24S (24 series cells) lithium battery packs with up to 100A continuous current, making it ideal for powerful applications where precision, protection, and reliability are key.

🔍 What Is the SQ24 100A Smart BMS?

The SQ24 BMS supports 24 series-connected cells, typically reaching a fully charged voltage of ~100.8V for Li-ion (NMC) or ~86.4V for LiFePO₄. With a 100A continuous discharge rating, it’s purpose-built for:

  • Electric vehicles (2-wheelers, 3-wheelers, and low-speed 4-wheelers)
  • Off-grid and hybrid solar energy storage systems
  • High-performance portable battery packs
  • Backup power systems (UPS)
  • Industrial lithium battery modules

It is a “smart” BMS, which means it goes far beyond basic protection. It offers real-time data monitoring, intelligent fault handling, and cell-level balancing, helping to ensure that your battery system remains safe, efficient, and long-lasting.

⚙️ Key Features of the SQ24 100A Smart BMS

24S Cell Support

The BMS is designed for 24-series lithium packs, supporting both Li-ion (NMC) and LiFePO₄ chemistries. This makes it versatile for a wide range of EV and ESS applications.

💪 100A Continuous Current

With a 100A discharge rating, the SQ24 BMS can handle heavy current loads, making it perfect for mid-to-high power systems without compromising safety.

📱 Smart Communication Capabilities

Some variants of the SQ24 come with communication options such as:

  • Bluetooth (via mobile app)
  • UART / RS485 / CAN protocols for integration with controllers or displays

This enables users to:

  • Monitor pack and cell voltages
  • Check current flow in real time
  • View charge/discharge cycles
  • Detect temperature variations
  • Get alerts for fault conditions

🌡️ Built-In Safety Protocols

The SQ24 BMS includes protection for:

  • Overcharge and undercharge
  • Overcurrent and short circuits
  • Over-temperature and low-temperature
  • Cell imbalance

These protections work automatically and are constantly monitored to prevent damage to the battery and connected equipment.

🔧 Passive Cell Balancing

To extend pack life and improve performance, the SQ24 performs passive balancing of individual cells during charging—reducing the voltage gap between cells and avoiding overcharging.

🛠 Applications of the SQ24 100A Smart BMS

The SQ24 is well-suited for systems requiring high voltage and moderate-to-high current, including:

  • 🚘 Electric rickshaws and cargo vehicles
  • Home and commercial energy storage
  • 🔋 Solar backup battery banks
  • 🏭 Industrial tools and robotic platforms
  • 🚲 Custom-built electric bikes with extended range

🧠 Why Choose SQ24?

Choosing the right BMS is more than just matching the voltage and current—it’s about ensuring stability, data visibility, and system health. The SQ24 BMS stands out due to:

  • Sturdy build and high-quality components
  • Customizable settings and protections
  • Smart app and controller integration options
  • Support for large-capacity packs with minimal heat generation

It offers a complete solution for integrators, OEMs, and serious DIYers looking for a dependable BMS for 24S lithium packs.

Conclusion

The SQ24 100A Smart BMS is an excellent choice for anyone working with 24-series lithium battery systems where power, safety, and intelligence are essential. With advanced features like Bluetooth monitoring, smart protection logic, and high current support, it is perfectly suited for EVs, energy storage, and industrial lithium solutions.

If you need a robust, smart, and scalable BMS for your next battery project, the SQ24 100A is a system you can trust.
