Woah, thats alot of new stuff to know. Thank you for your responses and time You guys probs saved my teeth only just by informing me about the battery amperage and im glad i've choosen way safer ohm range. Also now i see why the mods body got bit warm after every hit on 0.31ohm, even then i took the battery out asap to check, but it was kinda cold, so i taught its the RDA transfered the heat to the body.
