Hi guys. I also had the check battery problem. Got it fixed after reading through the replies. Thanks. I went to the mod tab and checked if it's on 2 cell. It was on 2 cell. Then I clicked on watt-hour calculator. A window pops up asking if u know the voltage of your battery pack. Clicked yes. Then you can enter the capacity (ex.2500mah) and number of cells and nominal pack voltage.(The 2 or 3 batteries voltage combined) you click ok and it calculates it then ask you to use those values. Click yes. Then go to the top of the screen to the upload settings to device tab. THAT was it. This worked for me. Hope it helps.
