  1. SS4-100 Semi Smart BMS – Built for 12V Inverter-Based Lithium Systems As the shift toward lithium battery technology accelerates in both residential and mobile power applications, the need for effective battery management is more crucial than ever. Whether you’re running a home inverter, RV backup system, or a small solar energy setup, protecting your lithium battery is essential for safety, performance, and long-term reliability. Enter the SS4-100 Semi Smart BMS— a practical and powerful solution designed specifically for 4S lithium battery packs (12V nominal) used in inverter-based systems.

  2. What Is the SS4-100 Semi Smart BMS? The SS4-100 is a semi smart Battery Management System developed by Lithion Power. It is engineered for 4-series lithium battery configurations, supporting both Li-ion (NMC) and LiFePO₄ chemistries. With a high continuous current handling capacity of 100A, it is well-suited for use in power inverter systems, ensuring safe and efficient battery performance under load. Unlike a fully smart BMS, the SS4-100 offers essential protections and basic data connectivity—making it a cost-effective and reliable option for users who need strong performance without unnecessary complexity. Key Features Supports 4S Lithium Battery Packs This BMS is optimized for 4-cell (in series) packs, which form the foundation of 12V lithium battery systems commonly used in: • Solar backup systems • Inverter-connected home batteries • RV and off-grid mobile energy setups • Telecom and surveillance power supplies 100A Continuous Discharge With a 100A current rating, the SS4-100 can handle: • High-load inverters • Motors or appliances powered through DC-to-AC conversion • Simultaneous charging and discharging conditions This makes it ideal for medium to heavy-duty applications that rely on stable, high-current discharge. Essential Safety Features The BMS includes built-in protection for: • Overvoltage and undervoltage • Overcurrent and short circuit • Overtemperature and undertemperature

  3. These safety layers help extend battery lifespan and prevent dangerous operating conditions during power surges, high discharge cycles, or improper use. Semi Smart Communication (Optional) While it’s not a full-featured smart BMS, the SS4-100 offers: • Basic communication through UART or LED display modules • Support for battery status alerts and simple diagnostics • Optional Bluetooth modules for limited monitoring This allows users to stay informed without diving into complex configurations or app-based setups— ideal for users who prefer simplicity with functionality. Typical Applications The SS4-100 is an excellent fit for: • Home inverter batteries (12V lithium packs for backup or solar storage) • Recreational vehicles (RVs) with 12V systems ?Off-grid power stations and remote site installations • ?UPS and telecom batteries requiring stable, protected energy flow • • Custom DIY energy storage projects ? ? Easy Integration & Setup One of the biggest advantages of the SS4-100 is its plug-and-play design: • Clearly labeled terminals and connectors • Minimal wiring required • Compatible with most 12V inverter systems • Passive balancing for maintaining cell voltage harmony It’s a practical choice for both professional integrators and DIY users who want robust protection with minimal fuss. Why Choose the SS4-100? • Designed for 12V inverter-based lithium systems

  4. • High current output: 100A continuous • Semi smart monitoring for simplicity and cost-efficiency • Trusted Lithion Power build quality and reliability • Suitable for both Li-ion and LiFePO₄ chemistries If you need a dependable BMS without the complexity of fully programmable smart systems, the SS4- 100 hits the sweet spot between affordability, functionality, and performance. Conclusion The SS4-100 Semi Smart BMS is a purpose-built solution for managing and protecting 4S lithium battery packs in inverter-connected systems. It brings together the most essential features—high current support, critical safety protections, and easy integration—making it the go-to choice for anyone building or upgrading a 12V lithium energy solution. Whether you're powering your home during outages or keeping your RV adventures uninterrupted, the SS4-100 is a battery guardian you can trust.
