Ecig battery issue

I am using a clearette ecig batter (you maybe never heard of it) and logic cartomizers. I fully charge it and it works good with like 5 pulls. After that, the vapor gets week like the battery is low. I keep using it and the 3 blinks (like you reached the max cut off time) happens in 2 seconds. If I let the battery sit it’s normal. How can I fix this issue?
