Hello,
According to the datasheets for the L9963E and L9963, the country may be both “a Li-ion battery tracking and protecting chip.” There isn’t any specific point out that they might not paint with LiFePO4 batteries and it is doubtful if ST includes LiFePO4 batteries under “Li-ion” batteries. Want to verify if LiFePO4 may be used with those chips.
Thank You
