Hi everyone.
Can anybody tell me how to make a battery sensor temperature ? i tought about using LM35 and sticking it on the battery so i can figure out the temperature with arduino but it seem not a practical way for me because i think there must be some way to know the temperature by measuring the curent no ? anyway i am just saying ... can anybody help me how to buld one ?

You can't measure the temperature without measuring the temperature.
