Out of the blue my IPV4 says **_CHECK **_BATTERY_**_.** I knew the batteries were getting low but I hadn't considered taking the batteries that were charging with me to work. I know that the batteries are still getting low but it hasn't prompted the warning yet. I yanked the batteries before they were fully charged. I felt like a murderer. But in hindsight, I very well could have just started smoking again because I didn't have any power in my mod. Must try and see the positives..
