The Farasis S47 is a large-format 3.21V 46.5Ah LiFePO4 pouch cell designed for mobility battery systems. Its reference specifications combine approximately 149.3Wh of nominal cell energy, a slim laminated construction, 5C short-duration discharge capability and more than 3,000 standard cycles. Application symbols in the referenced manufacturer catalogue identify passenger cars, buses and commercial vehicles as relevant uses.
01 46.5Ah LFP Energy Platform
A nominal voltage of 3.21V and capacity of 46.5Ah provide approximately 149.3Wh per cell. The lithium iron phosphate cathode and graphite anode create an energy platform suitable for larger mobility modules where cycle durability, predictable voltage behavior and pack-level safety engineering are important design priorities.
02 Slim Large-Format Pouch Construction
The laminated pouch construction measures approximately 231 × 161 × 10.1mm and weighs 761 ±15g. This wide, thin format supports space-efficient module layouts, but the published illustration is simplified. Production tooling, compression structures and busbar geometry should therefore be based on the latest manufacturer drawing for tab and sealing-edge details.
03 5C Short-Duration Discharge
The S47 supports a specified 5C discharge pulse for 10 seconds at 25°C and 50% state of charge. Based on 46.5Ah, this corresponds to approximately 232.5A during the defined test. It must not be interpreted as a continuous-current rating, which is not stated in the available reference specification.
04 41-Minute Reference Charge Time
The catalogue reference lists a 41-minute charge time from 10% to 80% SOC under its stated manufacturer condition. Because detailed charge current, thermal controls and taper criteria are not included in this summary specification, system designers should obtain the latest validated charging protocol before configuring chargers or battery-management limits.
05 199.5Wh/kg Reference Density
Farasis lists a gravimetric energy density of 199.5Wh/kg at C/3 and 25°C. Combined with the cell’s flexible pouch format, this supports weight-conscious module development. Pack-level energy density will be lower after adding compression frames, cooling components, busbars, monitoring electronics, insulation, enclosure hardware and required safety protection.
06 More Than 3,000 Standard Cycles
Standard cycle life is specified at more than 3,000 cycles to 80% remaining capacity. This result uses C/3 charging, C/3 discharging, 90% depth of discharge and a 25°C test temperature. Actual service life depends on charge rate, discharge load, operating temperature, SOC window, cell matching and mechanical compression.
Custom battery pack applications: The Farasis S47 can be considered for passenger-vehicle, bus, commercial-vehicle and other engineered mobility battery systems after full technical validation. MisenBattery supplies cells and supports custom module and pack integration, including compatible BMS selection, fuse protection, welded or manufacturer-approved tab interconnections, voltage and temperature sensing, electrical insulation, cell spacing, pouch compression, thermal management and enclosure design. Availability and applicability of supporting CE, UN38.3, RoHS and UL documentation should be confirmed for the specific product batch, shipment and finished-pack configuration.
