Battery quality

It’s not the best but as good as needed to recharge and affordable
I’m a chain vaper so the highest quality can be more useful
Thank you

this battery has been tested with mulitiple other batteries... if you have tried other batteries you will notice a drop in wattage while you are vaping and the battery percentage is going down. its a very good quality compared to others as per practical tests. if in any way you have found another battery with the same rating that did deliver better results i'de be happy to know which one. good day to you
