Conanthewarrior Posted November 25, 2015 Author Report Share Posted November 25, 2015 Hi everyone. My New Wismec DNA200 should be turning up Saturday, and I have a question regarding W/h's. I have bought 3 brand new 25R's for the device-now does this make the battery pack 7500MAH, with over 27 W/h's, or should the W/h's be set lower than this? It was around 27.75, but I was thinking not each 25R may be fully 2500MAH, so 27 W/h's was more conservative. This was putting the voltage in at its nominal, 3.7V, and 7500MAH with the three 25R's. Have I got this right-and shall set it to a massive 27 W/h's, or have I miscalculated and it is much less? I wouldn't want to ruin a brand new device, So some advice on what I should set it at would be helpful. Thanks everyone, Conan. Link to comment Share on other sites More sharing options...
UKDTweak Posted November 26, 2015 Report Share Posted November 26, 2015 For 3x 25r, the WH should be 27.75, thats 2500mAh and 11.1 nominal voltage, but you Do Not have 7500mAh as the cells are in series. Link to comment Share on other sites More sharing options...

However Kidneypuncher.com web site tested a set of these and found they perform identical to 25R's in capacity. Whatever the subohmcell is it's definitely a rewrapped battery of some type. Using the settings from the watthour it calculator they are 31.08 wh. This is what I entered, right or wrong. Jumping ahead from a full charge to empty I'm getting 410 puffs with ending cell voltage about 3.25 volts when the battery meter shows empty and remaining watt hours shown on the monitor was showing about 1/3 of 1 watt hour left. So should you set yours to 2500 or 2800? Good question, I'd try 2500 if I were you and see if your battery meter is accurate. If not, make an adjustment or run battery analyzer.
