    HI Guys, been browsing this forum months already without any posting :)

    i have an issue here with my Reo Grand. it just happened recently..

    when i test fire the Reo (measured by voltmeter) without atty it get 3.75v, however when i screw in the atty the voltage dropped to 2.8v which is almost 1v difference!

    i have change all parts using repair kit from reosmods and the result still same. before this the difference is only about 0.2-0.3v. i have no idea what is the cause of this problem now :(

    FYI, i'm pairing the Reo with ERA, but my test has been done using smoktech carto, ERA and phoenix, the result was similar for all atty.

    Appreciate fellow ECF assistance on this. :)

    are all of these dual coil? Because that could put the strain on your battery...

    Hi elmattias,

    My ERA is single coil rated at 1.4ohm, the phoenix is single coil rated at 1.6ohm and the carto is dual coil, forgotten the resistance value.

    All are working fine when tested at my smoktech telescope. The voltage difference is only about 0.2-0.5v.

    Will search for isopropyl, maybe soaking the whole reo into iso will clean all contact points.

    Sounds like your battery is undercharged and perhaps nearing the end of it's useful life.

    Try a new AW IMR 18650 or a Panasonic CGR18650CH (nipple tops work best in the Grand)

    A freshly charged battery will meter around 4.20 volts fresh off the charger and will drop 2 or 3 tenths under load, depending on the resistance of the atty/carto.

    your battery should come off the charger around 4.2v you will see a drop on a inline volt meter with a Reo non VV but it shouldn't be that much. When I was using non VV Reos I would be changing the battery when it hit 3.8v - 3.7v

    Is it safe to charge the batt at 3.8v? How do you measure the volt before charging? I guess it should be unloaded value right?

    To trouble shoot this you are going to need a multi meter and a screw in 510 connection load meter. You can get both for under 30 bucks and they are the most useful vape gear I have. When I get to the computer I will give you some links.

    Ok, here is the picture on how i tested the Reo.

    Unload reading is 4.05v
    uploadfromtaptalk1352213870055.jpg

    The atty is at 1.2ohm (my multimeter's error is aroung 0.6)

    Loaded reading is at 2.76

    Although your getting help from some of the top reo experts, one more post and you'll be able to post in the Reo subforum.

    Reos Mods

    A 1.2ohm atty is going to need to draw a lot of amps (3.4a) to get even close to your unloaded voltage. My first guess would be that your battery simply isn't up to the task.

    Didn't aware that i need to have at least 5 posts to post in Reosmods forum...;)

    BTW these are the pictures of the same test on my telescope.

    Unload reading is 4.13
    uploadfromtaptalk1352215595768.jpg

    Onload reading is at 3.7
    uploadfromtaptalk1352215595768.jpg

    It seems normal on my telescope..as what i do understand voltage drop range of 0.2-0.5 in mechanical mod is normal.

    Just tested on my telescope with the same battery used in Reo.

    Unload reading : 4.02
    Loaded reading : 3.54

    I guess the battery is not the issue.

    Yes. Yes. Please post links when you can. I am really wanting a Reo, but I need to get prepared to properly use the device. I am convinced that going to a mod requires a little more knowledge & expertise than using my Kgo.
    Thanks in advance, Dan.

    That leaves nothing but the battery connections, the connector, and the switch to sort out in a Reo.

    How to check other parts in Reo whether they are working fine? Using multimeter?

    Emailed him already, and now wait for an advice from him.

    Broken insulator will result shortage IMO. mine is still firing, only at lower loaded voltage. I'll give a try by replacing the insulator later. Thanks for the link!

    Can you show me the battery you are using. Also I didn't see a picture of that same load on the telescope, with the same battery.
