Molicel P42A 21700 4000mAh 45A Battery

These are the best all around cells I've used. Great for regulated vaping and stellar for mechs. Battery life for days!

Definitely some great batteries definitely recommend them for anyone using a Mech

Running my boxer 100c great

These are the best all around batteries I have ever used. Not only do they last a long time with 4000 mah, but with a 45amp rating they run my series mods like nothing else!! I have used these in both regulated and mech mods, single battery, dual, stacked tubes and they just keep going and going!! Seem to have acquality build to them as well as they have not dimpled or dented in from my tube mods like some cheaper batteries do.  The outer wrap and insulator ring seem to be of very good quality as well!!  As always,  Demitri and the crew at Straight Fire Vaporium were on point with top notch service and quick shipping.  They even came in nice plastic storage containers instead of little cardboard boxes like so many others!!  I will definately be a repeat customer for these batteries in the future and will definately be getting them at Straight Fire Vaporium
