Kangertech Starter Kit Battery wont work.

[Audebroo]

When I insert the charged battery into my own, it shows the amount of power available for 1 second, and then starts blinking with the no power icon. I tried inserting the battery on some of my friends (same model) and it worked for them. What can possibly be the issue?

Which kit is this?

 

What tank are you using?
