Thanks Katya!
Div, Yeah... no instructions. unfortunately. For the lights... It's the same as the other EGO-C batteries. It should flash 3 times when toggled on or off. When depleted, I believe it flashes 15 times. You know it's depleted, because it wont light back up, until plugged in. There are also warning lights, that may flash if connected to a bad atomizer. If you notice this, remove and test the atty before further use.
Also, regarding the AMP limit - I still can't get a straight answer (and it's not for lack of effort). I've explained it every way I can think to, and they just keep saying that if turned up to 4.8v, it should output 4.8v, and they just won't consider the load.
My experience with the device, has been great. I still use DC cartos on there, as the voltage is still higher than a standard ego battery, even at 3.7v, and am quite pleased. I do like the Boge or Smok Tech 2.0's on there also. but I tend to crank them up a little higher (because I can) and still get about 2-3 days use, per carto. It's like a little lavatube (and it's EGO compatible). and since I got mine, I dont really take my MODs out of the house anymore. I just bring 2 EGO-C Twists, and i'm golden
