FLYFINE · FS48314 / FS48628
The FLYFINE floor-standing LiFePO4 battery series offers 314Ah and 628Ah capacity options for compatible residential solar storage and backup power systems. Both models operate at a nominal voltage of 51.2V.
The FS48314 provides 16.077kWh of rated energy, while the FS48628 provides 32.15kWh. Grade A+ lithium iron phosphate cells, BMS and circuit breaker protection, and CAN/RS485 communication support integration into compatible energy storage installations.
Select 16.077kWh or 32.15kWh of rated energy according to the project's storage needs. Both models use a 51.2V nominal battery architecture.
New Grade A+ LiFePO4 cells are paired with a battery management system and circuit breaker, providing two levels of overcurrent protection.
CAN and RS485 interfaces support compatible inverter communication. Bluetooth and Wi-Fi monitoring are available as optional functions.
Both models are specified for at least 8,000 cycles at 25 ± 2°C and 0.5C charge/discharge rates, with an 80% end-of-life capacity threshold. Actual service life depends on operating conditions.

*Cycle-life test conditions: 25 ± 2°C, 0.5C charge / 0.5C discharge, with an 80% end-of-life capacity threshold. Specifications are subject to change. Confirm the final product configuration and optional functions when ordering.
Provides 16.077kWh of rated energy. Select this model when its usable energy and electrical limits meet your daily storage or backup requirements.
Provides approximately twice the rated energy of the FS48314. It supports projects requiring more stored energy, while retaining the same specified 200A maximum charge/discharge current.
Higher energy capacity does not automatically mean higher output power. Check battery current limits, inverter ratings and load demand when sizing the system.
Store solar energy through compatible inverter and charging equipment for later use. System settings determine charging and discharging behavior.
Pair the battery with a compatible backup-capable inverter to supply selected loads during an outage. Backup duration depends on usable battery energy, load demand and conversion efficiency.
These are 51.2V nominal batteries for compatible 48V-class systems. Their specified battery voltage range is 43.2–57.6V. Confirm that your inverter supports this range and the required communication protocol.
FS48314 provides 314Ah capacity and 16.077kWh rated energy. FS48628 provides 628Ah and 32.15kWh. Both models have a standard charge/discharge current of 100A and a maximum of 200A.
No. It provides approximately twice the rated energy, while both models have the same specified maximum charge/discharge current. Available system power also depends on battery voltage and inverter limits.
The 314Ah battery is offered in standard and covered enclosure versions. Specify the required version and confirm the final configuration with FLYFINE.
Both models have an IP21 rating and should be installed in a suitable protected indoor location. They should not be exposed directly to rain or outdoor weather.
Bluetooth and Wi-Fi are optional functions. Confirm your required monitoring configuration when requesting a quotation.
For distribution or installation projects, send FLYFINE your preferred model (FS48314 or FS48628), required quantity, destination market, inverter model and monitoring requirements. For the 314Ah model, please also specify the preferred enclosure version. Our team can confirm the configuration and provide a quotation.
