  1. Does it push 40A? Yes. Does it push those 40A without damaging itself? Not at all.  star rating

    This battery does push 40A/80A, and does so without any sort of temperature increase or venting (even seems more resistant to hard shorts, somehow). However, pulling such a high amperage over the course of numerous cycles can reduce your battery life to mush. Aspire did deliver on their promise of an amp rating that can beat even Sonys, though at a price. Still solid batteries, though, just don't go crazy with them and you'll be happy.

  2. 40 amps?  star rating

    I don't know about the 40 amps but it does seem to do very well with voltage drop. I like this battery

  3. Noticable difference  star rating

    I love using this battery with my mech mod,i use a Marquis rda with a single giant coil,24 gauge kanthal wire coil. It took around 10 wraps to get my desired resistance of .07. With this batt it ramps up better than the green sonys i been using. For a mech mod guy like me who enjoys a good sub ohm vape, this is my new go to batt !
    Thanks EVC for keeping the goods in stock !
