Low temperature designation

LOW-TEMP means charging is blocked below 0°C, not enabled

“Resume Charging Temperature Under LTCP 5°C/41°F (Battery Temperature) ② The 12V 200Ah LOW-TEMP battery supports Low Temperature Charging Protection (LTCP), where the BMS stops battery charging when the battery temperature falls below 0℃/32℉ and resumes charging when the temperature rises above 5℃/41℉.”

Maximum bank configuration

16 packs, as 4 in series by 4 in parallel

“LIMITATION FOR SERIES/PARALLEL CONNECTION Support connecting up to 16 identical batteries for up to: 4 in series as 48V (51.2V) battery system/ 4 in parallel as 400Ah battery system.”
