    I've been TRYING to do the research, honest.

    I have an Aegis Legend coming soon.
    When I ordered it, I got a LUC v4 charger and the Samsung INR18650-30Q batteries for it, but now I'm wondering if I made a mistake?

    I've looked through threads here, and Mooch's charts and info, and the reddit thread on the Legend battery testing:

    http:// GeekVape Aegis Legend battery life test! But on factory firmware, new update available today. : electronic_cigarette

    ... but I'm still not sure about whether I should go with the 20s or (24s?) instead. :?:

    I'm more interested in battery life and safety than high wattage vaping.

    Thanx for any help.

    I’ve been vaping an ageis legend lately with a berserker mini rta running 1ohm coil at 8w. I generally vape quite a lot. The thing will go for almost two days before the batteries need to be changed. I doubt you’re going to have a problem

    If you search for Mooch’s battery testing 30q’s are fine in a regulated mod for under 45 watts vaping from what I remember. I can’t remember exactly but the watts used can be increased with 2 batteries.

    Your link to the reddit thread isn't working.

    As long as you don't vape over 90 watts (45 watts x 2 batteries), the Samsung 30Q's will be more than sufficient. With 3000 mAh each the 30Q's should last quite a bit longer than the 2500 mAh each of the 24S or the 2000 mAh each of the 20S. You don't need a higher amp battery the way you vape.

    (Total wattage doubles using 2 batteries; Triples using 3 batteries.)

    Up to 45W:

    The above chart is just an expanded version of the chart Mooch has in his below video.

    The original Aegis Legend I believe had a battery efficiency glitch which could be corrected with a firmware update. When you get your Legend, check which firmware is loaded on it and make sure it is the latest version.

    Battery life will be dependent on how efficient the device is and your vaping patterns – wattages, frequency etc. For a regulated device, to determine what battery(s) to choose, take your preferred wattage, divide by the amount of cells, this will equal Watts Per Battery (Wbatt).

    Then divide by the cut off voltage of the device and efficiency of the device. We rarely know the efficiency unless it is stated within the specs so safe to use 0.9 (90%). This will equal your Amps Per Battery (Abatt)

    So if you prefer to vape at 80 watts with the Aegis Legend which has 2 cells and a cut off voltage of 3.2 volts…

    Wbatt = 80/2 = 40

    Abatt = 40/3.2 (cut off voltage)/0.9 = 13.8 amps per cell.

    The Samsung 30Q would be more than sufficient in this case.

    30qs same as you. I originally bought them for DL vaping at 35w. Then they lasted a good full day.
