Frequently Asked Questions about Battery Technology

What is the cycle life of your LiFePO4 batteries compared to lead-acid batteries?

FNS Power LiFePO4 batteries offer a cycle life of over 6000 cycles at 80% Depth of Discharge (DOD) and 25°C, significantly outperforming standard lead-acid batteries. This longevity, combined with a 98% efficiency rating, provides a lower cost per kWh over the battery’s lifetime, making them an ideal deep cycle battery replacement for solar and RV applications.

 

 

Can the Residential LV EnerStack Battery system be expanded for higher energy capacity?

Yes, the Residential LV EnerStack Battery features a modular design that allows for flexible expansion. It stacks in 5.12 kWh increments, with a single stack reaching up to 25.6 kWh. The system supports up to 10 stacks in parallel, achieving a maximum capacity of 256 kWh, making it scalable for both home backup and off-grid residential energy storage needs.

 

 

What safety certifications do your lithium battery modules comply with?

Our battery modules, including the 48V 100Ah LiFePO4 series, comply with rigorous international safety standards such as CE, CB, UL, and UN38.3. These certifications validate the product’s safety, reliability, and transport compliance for global telecom, UPS, and renewable energy storage applications.

 

 

Are your deep cycle AGM batteries suitable for solar energy systems?

Yes, our deep cycle AGM batteries are designed for off-grid and hybrid solar systems. Featuring Absorbent Glass Mat technology, they are maintenance-free, spill-proof, and offer high resilience to deep discharging. They are an excellent choice for storing solar energy in residential and remote applications where cost-effectiveness and reliability are key.

 

 

What is the function of the intelligent BMS in your battery energy storage systems?

The intelligent Battery Management System (BMS) integrated into our BESS solutions provides comprehensive protection against over-voltage, over-current, short circuits, and overheating. It features automatic cell balancing to extend cycle life and supports remote monitoring and OTA updates via RS485 or CAN communication, ensuring safe and efficient battery operation.

 

 

How does the FNS 48V 100Ah battery module support telecom backup applications?

The FNS 48V 100Ah lithium module is specifically designed for telecom system backup power. Its high energy density (4.8 kWh) and compact 5U design save space in server racks. With a wide operating temperature range (-20°C to 50°C) and high charge/discharge efficiency, it ensures reliable UPS performance and reduces energy costs for data centers.

 

 

What is the warranty period for the Residential LV EnerStack Battery?

The Residential LV EnerStack Battery comes with a 10-year limited warranty and is engineered for a 20-year design life. This long-term guarantee covers performance defects, ensuring homeowners and installers a reliable return on investment for their home energy storage systems.

 

 

Can I use LiFePO4 batteries to replace AGM batteries in my RV or Marine system?

Yes, LiFePO4 batteries are the ideal lead-acid replacement for Recreational Vehicles (RVs) and Marine systems. They offer 50% lighter weight, double the usable capacity, and significantly faster charging compared to AGM batteries. Their non-toxic chemistry and deep discharge capability make them safer and more efficient for mobile power applications.

 

 

What are the charging recommendations for the 48V 100Ah battery module?

For optimal lifespan, the recommended charge current for the 48V 100Ah module is 50A, with a maximum allowable charge current of 100A. The battery operates within a voltage window of 40.5V to 54V. Proper charging ensures the module maintains its rated capacity and extends its cycle life beyond 6000 cycles.

 

 

Do your battery systems support integration with third-party inverters?

Yes, our battery systems, particularly the LV EnerStack and 48V series, are designed for compatibility with most mainstream low-voltage inverters. This plug-and-play compatibility simplifies installation for residential and commercial energy storage projects, allowing for seamless integration with existing solar inverter infrastructure.
