Can't really go wrong with these. I've been using one for a year and it's still going strong. There are a couple comparable but the 40T is still the industry standard for higher cap 21700 vape cells.
I love it a lot!! Keeps a long charge and has a lot of power/life
Great batteries, going to order more. Like to stick with well known brands when it comes to batteries. These are one of them.
It is an excellent high current and capacity cell and seems to be one of the best at the current time in this size battery. Bought this to power my Geekvape Aegis max 100W device from GCV. As always best customer service and satisfaction from GCV.
Doesn't last all day but with one back up battery its fine.
