Just get my AWT 26650 4500mAh yesterday. Everything went well this morning, until just now, my battery left half bar at the battery indicator. I was vaping with 0.39ohms SS316L dual coil at 40watts 230degC. After a puff, it show up Weak Battery. I know AWT 26650 written 75A is a hype. Can someone teach me how should I do? I run through this catagory but seems like I am the only that have this problem.... Thanks in advance.
