I contacted Bienno for their Lithium Iron Phosphate (LiFePO4) Battery Model BLF-1209WS and they said the following;

The operating temperature is from -20 deg C to 60 deg C (14 deg F to 140 F). Then charge between 0 deg C to 40 deg C (32 F to 104 F)

I left a message for Stark, and will forward the response here.
