does the battery's BMC have low temperature protection?

Our BMS can allow the 12v 100ah batteries to be charged at low temp environment from 32°F To 140°F and discharge at low temp environment from -4°F To 140°F.

can i use four of your lithium iron batteries connected in series, so it's 48v, with my 5000w electric bike motor and 48-72v 80ah controller?

The battery protection board is 100A, if your controller current exceeds 100A, it cannot be used, The controller current can be used within 100A.thank you.

Would it be ok to put 2 of these batteries in parrallel to use with a 12v 30amp solar charge controller?

If it is two identical batteries, it can be used in parallel, thank you.
