THE 21700 (31 January 2020)

True to description. Equal drain for both batteries on all my dual mods. These are most popular for a reason. 3000mah 100% accurate. Best 21700 by far for me. Worth the upgrade from cheaper 21700's I've bought.

Perfect battery (12 August 2019)

This battery is perfect for all mods! The battery really gives you the power it says it would [3000 mAh and 35 amps]. I use the samsung t30 for my mech mods just the be safe. if you dont trust your battery search for Mooch on google he almost test every battery and tells you the real power of the battery, because some company's dont tell you the true power of the battery!

Very Impressive! (15 May 2019)

Bought 2 of these batteries for my AsMODus Amighty-mod and i could not be happier.
They perform very well at around 55-60watts, i haven’t tried them on higher wattages yet and i probably won’t as i’m more of a flavour chaser and rarely go over 70 watts when i’m vaping.
I can’t come up with anything bad to say about these batteries.
They last a day and then some at the temparatures/wattages i vape at.
At first i tried using the purple/blue batteries from Vapcell in the same mod but both the wrap and insulator ring got shredded when i removed it which sucks cause they are also very good batteries and cost a fortune over here(like 45£ for 2 cells), but these batteries from Samsung were a great fit and i don’t think the price is too shabby for 2 high quality cells(Battery-guru Mooch also gave these batteries high remarks).
Totally worth it and i will probably buy more if these.
Shoutouts to @Vapeclub for supplying two extra battery condoms in my shipment!(Y)
Thank you!
