    Soooo...I wonder if that liquid electrolyte is what causes the darkening mystery on some of those green batteries ???


    Hey @Mooch

    I tend to not think so as it would have a very strong solvent-type odor and the performance of the battery would drop significantly.

    I think the marks are caused by different things; eliquid, lubricant or release agents from the metal can drawing process, or body oils through pinholes (I've tested this).

    [QUOTE="Mooch, I'm trying to write for you in direct but I don know how

    "best battery" is an individuals choice based off amperage drawn on your device. Click on the "B" next to Mooch on his previous post for blogs that contain a lot of battery info and will give you your answers.

    I'm new to mech mods what is the best and safe battery for mech now I'm using Sony VCT4 please I need your opinion I'm so worried using mech mods?
    Mooch can speak for himself, but I'm pretty sure he won't mind if I jump in here until he does.

    Choosing which battery to use is always a choice between amp rating vs mAh capacity. You can't have the highest amp rating (30 amp CDR) and highest mAh capacity (3000mah) in a single battery; it tends to be one or the other. With a mechanical mod using subohm coils, the amp rating must always be your highest priority, and the mah rating will be your secondary priority. Depending upon how you vape, you must decide if you need a 20 or 30 amp battery.

    Your Sony VTC4 is a 23 amp CDR and 21000 mah battery according to Mooch. Sony VTC4 2000mAh 18650 Retest Results...a great 23A 2100mAh battery You could use coil builds down to 0.2 ohm with that battery. You could do better than that with a higher capacity (mah) longer lasting battery if you don't mind sacrificing 0.1 ohm with your coil builds.

    In the interests of keeping things simple:

    The Sony VTC6, Samsung 30Q, and LG HG2 each have 3000mAh and 20 amp CDR. Either would be a good choice as long as you keep your coil resistance at 0.3 ohm or higher.

    Sony 18659VTC6 3000mAh 20A CDR
    Samsung 18650 30Q, 3000 mah 20 amp CDR
    LG 18650HG2 3000mah 18 amp CDR


    With a 30 amp battery you can build down as low as 0.2 ohm, but you lose mAh capacity with only 1500 mah. The LG18650HB6, LG18650HB2, or LG18650HB4 with 1500mAh and 30 amp CDR are your choices. Note that as you gain amps you loose mAh (capacity); does that extra 0.1 ohm really matter that much to you to loose all that capacity?

    LG18650HB6 1500mah 30 amp CDR
    LG18650HB2 1500mAh 30 amp CDR
    LG18650HB4 1500mAh 30 amp CDR


    * Coil amp draw from Ohm's Law calculations for Mechanical Mods:
    1.0 ohm = 4.2 amp draw
    0.9 ohm = 4.6 amp draw
    0.8 ohm = 5.2 amp draw
    0.7 ohms = 6 amp draw
    0.6 ohms = 7 amp draw
    0.5 ohms = 8.4 amp draw
    0.4 ohms = 10.5 amp draw
    0.3 ohms = 14.0 amp draw
    0.2 ohms = 21.0 amp draw
    0.15 ohms = 28 amp draw
    0.1 ohms = 42.0 amp draw
    0.0 ohms = dead short = battery goes into thermal runaway
