The FelicityESS FLB48314TG1-H 51.2V, 314Ah lithium battery is a high-tech energy storage solution designed for use in the most demanding conditions. This FLB series battery is manufactured using safe lithium iron phosphate (LiFePO4) chemistry and advanced CCS welding to reduce internal resistance and improve efficiency. Key features include a built-in heating system for low-temperature operation, a patented external, easy-to-replace fuse, and the highest IP65 protection rating, ensuring complete sealing and resistance to external influences. This battery is designed for powerful backup and standalone power systems in private homes, commercial properties, and locations with harsh climates requiring sub-zero temperature operation. It stores excess energy from solar power plants, ensures uninterruptible power supply to critical equipment, and ensures complete energy independence. With the ability to connect up to 32 modules in parallel, the system can be scaled to enormous capacities, while the high IP65 protection rating allows for outdoor installation. The product is ideal for professional installers, business owners, and anyone who demands maximum reliability, safety, and durability in any operating conditions. - Built-in active heating system (Heating) for safe charging and stable operation at sub-zero ambient temperatures. - The highest degree of protection of the IP65 case, providing complete tightness, protection from dust and jets of water, which allows the battery to be installed both indoors and outdoors. - Built-in active fire protection system with aerosol fire extinguishing for maximum safety. - LiFePO4 technology with a long service life and stable operation throughout its service life. - Advanced CCS welding (Current Collector Sheet) to reduce internal resistance, increase efficiency and ensure high-speed charge / discharge. - Modular design with the possibility of parallel connection of up to 32 units for flexible expansion of the system capacity. - Built-in Wi-Fi / Bluetooth module for remote monitoring of battery status and operating parameters via the Fsolar mobile application. - Convenient patented design with an external easy-to-replace fuse for quick maintenance without disassembling the case. - Comprehensive protection system: built-in intelligent BMS, circuit breaker and fuse. - High compatibility with leading inverter brands thanks to built-in CAN and RS485 interfaces.
