Conqto Li-ion Battery 3.7V 3400mAh 20A, Rechargeable Flat Top with Storage Case (Pack of 2), Batteries for Vape, Doorbell, Torch, Camera, Flashlight, Headlight

Having always purchased Samsung 25R’s and consistently vaping around 55w 0.19ohm, I’ve always struggled to get a decent battery life and found my device will display “low power” at around 45% battery life. NOT ANYMORE! These are incredible and can be used right to the end.Very impressed and work flawlessly for my requirements.

Just standard 18650 cells, but nearer to their stated capacity than most. Instead of 3400 mAh I saw 3219 and 3107 mAh. Tester was Amazon B07G7Z9P5H.

Cable looked the beans , but put on machine and only works on a few ecusAnd machine kept saying no come.So will be returning it.Shame as it is a good made lead but not wired correctly or something.

I use them in my e-cig, they do the job and hold up about as well as my 3k EFEST.

Yes, that'll do nicely. Meets the specifications stated.

The batteries are well priced and simple to use. They work as i had hoped and seem to hold their charge well.

These battery's drain too quick, ideal to have a charger with you,

Easy 2 use with case delivered quickly
