And test with different cables. They vary in resistance. 5 volt at the battery might be 5 volt at the end of the cable with no current draw but only 4.9 or 4.75 when there is current drawn. Use a multimeter to test at the battery then at the end of the cable then at the end of the cable with the Pi plugged in then with the Pi active. You can measure the Pi 5 volt at the 5 volt GPIO pin.
