Thank you guys for helping. I have re-flashed the current SP and hard rebooted the device for good measure afterwords and still have the same problem. I will send it in for repair and will update with what the issue was if they inform me.

I have attempted a couple of hard reboots but am not familiar with re-flashing the firmware or where to find the firmware. I finally got a hold of Axis and they are going to RMA the device. Hopefully they will let me know what the issue is in case someone with the same issue is lurking.

Yes this cable and wallplug will charge at 2a with another dna250. The one that currently charges at 2a has a usb voltage of 4.73 according to the board. The mod that is messing up is showing 4.26 on the board using the same cable and charger. I have three different 2A wall plugs and have tried at least 5 different cables on all of them with the same effect of not being able to charge past .6ish.

Also, I have noticed that when it is charging at a super low amperage, like .16, the voltage will be around 5v but when it is charging at .59 the voltage will be much lower like around 4.2x.

I am having the exact same issue with my Axis M17, DNA 250. Charged fine at 2a up until recently. I have a Therion 166 and it will charge at 2a using the same cable and wall plug. I have contacted Axis about this and they tell me that it should only charge at 1a and that that was why it wasn't charging at 2a. According to their website the lipo they sell can charge up to 5a and the dna250 can charge at 2a. I'm not really sure why they are telling me I can't charge past 1a. But even if it could only charge at 1A, why is it not charging at 1a? I have also noticed that when left plugged in for an hour or two it will say it's only partially charged then after using it for a bit the battery percentage will shoot up to near 100%. I set the watt hours in escribe to match the description of their battery when I first got it and it worked fine for a month until it started acting up. I have changed the watt hours now to what it was charged at when it was showing 100% but that didn't remedy the battery percentage jumping.
DNA 250 only charging at .59a

Axis has repaired it and sent it back without informing me of how they resolved the issue. I did try to call and ask but didnt get a hold of anyone and have forgotten about it til now. I did notice they set my watt hours to 9. I'm wondering, but not sure at all, if the issue was because I set the watt hours to 12.2, which is what they advertise their lipos at, was the cause of the issue. That was one of the first things I did. According to their site adjusting the wh voids the warranty but they handled it without grief after I explained the issues I was having. I also noticed the chip was set back to factory. Wish I would of thought to write down my serial to find out if it's a new chip. If escribe keeps track of that I could find out for you.
