德国采购需求：电池管理系统，BMS电池，BMS模块，锂BMS，BMS锂电池，适用于Lifepo4的BMS

I recently purchased a BMS and have a question about the NTC connections. Due to limited space, I can't access the NTC-1 port, so I'm considering using NTC-2 as the primary temperature sensor. However, after connecting to NTC-2, the app displays -40°C. I suspect this is because NTC-1 is not connected to any sensors. Can I use NTC-2 exclusively and ignore NTC-1? I would appreciate any guidance on whether this setup is feasible and if it might cause any issues. Thanks for your assistance!
