The SHS150-45-LFP is a semi-solid-state lithium iron phosphate pouch cell with a typical capacity of 45Ah and energy of 144Wh. Its flat construction, specified 1C charging and discharging rates, and discharge temperature range of −30°C to 60°C support evaluation for custom energy storage and backup power assemblies. MisenBattery supplies the cell and supports pack integration tailored to the project’s electrical, thermal and mechanical requirements.
01 Semi-Solid-State LFP Technology
WeLion identifies the SHS150-45-LFP as a semi-solid-state cell using lithium iron phosphate chemistry. Its nominal voltage is 3.2V, with specified upper and lower voltages of 3.65V and 2.5V. These values provide the basis for selecting compatible charging equipment and defining the voltage architecture of a custom battery assembly.
02 45Ah Typical Capacity and 144Wh Energy
A typical capacity of 45Ah and stated energy of 144Wh provide a clear reference for preliminary pack sizing and runtime estimates. The cell can be evaluated for energy storage and backup power projects requiring rechargeable pouch cells. Final usable system energy depends on the selected operating window, load profile and pack design.
03 1C Charging and Discharging
The datasheet specifies standard charging and discharging at 0.5C, alongside fast charging and discharging at 1C. Using the 45Ah typical capacity, these rates correspond to calculated currents of 22.5A and 45A respectively. This provides a useful starting point for charger selection, current monitoring and application-specific electrical design.
04 Discharge Operation from −30°C to 60°C
A specified discharge temperature range of −30°C to 60°C supports evaluation for systems exposed to varying ambient conditions. Charging has a separate operating range of 5°C to 55°C. Pack temperature sensing and control should manage these distinct limits, including preventing charging when cell temperature falls below the specified charging range.
05 Defined Cell-Level Energy Density
WeLion specifies gravimetric energy density of 148Wh/kg and volumetric energy density of 290Wh/L, with a cell weight of 971 ± 10g. These cell-level figures help engineers compare mass and volume requirements during concept development. Completed pack calculations should also include the enclosure, interconnects, protection electronics and thermal management components.
06 Flat Pouch Format with Opposite-End Tabs
The cell body measures 11.7 × 118 × 359mm at nominal dimensions, with tabs positioned at opposite ends in the manufacturer drawing. Each tab is specified at 30 ± 1mm long and 60 ± 0.2mm wide. This defined geometry supports planning of cell placement, interconnect routing and terminal clearances within custom modules.
Custom battery pack applications: MisenBattery supplies WeLion cells and supports custom pack integration for energy storage, backup power and other qualified rechargeable battery projects. Pack designs should include a compatible BMS, fuse protection, voltage and temperature sensing, insulation, suitable spacing, thermal management and pouch-cell mechanical support. Confirm manufacturer-approved tab joining methods, including welded interconnects where applicable. Applicable CE, UN38.3, RoHS and UL documentation requirements and availability should be verified for the exact cell, finished pack and shipment.
