    Lowest resistance for use with parallel 25Rs in a full mech mod?

    Ok so I am hoping someone can help me to not burn my house down. I've got a new mod, pictured below. It's a full mech mod and is solid. I imagine it could handle just about anything I throw at it. It is set up to run 18650's in parallel. I will be using two 25R's and am thinking that by running parallel batteries, that the available amperage doubles? So I can build a resistance of .xx that will draw up to 40 amps continuous. Is this right?

    That logo could have with being tilted a bit more so it was on the flat face fully.

    Yeah true, or just made the logo a fraction smaller so it fit in the flat space. I'll prolly end up buffing it off at some stage anyway and or might patina the whole thing.

    25r 's have a 25A drain limit (the new ones).... On a mech your initial voltage will be 4.2, giving you a min resistance of 0.168. You would be unwise to push this low though, as your ohm meter might be slightly out. 0.3 should leave enough room for safety but personally I don't take mine below 0.4.

    Theoretically the current in the cells can be added together BUT if one cell fails the other will be seriously overtaxed... You could be holding a bomb to your face and pressing the button. (worse case scenario, but possible )

    I appreciate your advice. My Samsungs were purchased 3 months ago, so not sure if they are the old or new variety. Is there a way of telling which is which?

    My biggest fear is that I might die and my missus will sell my vape gear for what I told her it cost

    Should be able to find out from who you purchased them from. Normally advertised on the product page which version they are.

    That's definitely outside of the safety boundaries.

    I've bought so much stuff from so many places, I really cant remember where I got them from now. I'll research this later, maybe I can find out from the numbers on them. Again thanks for the info.
