Hello all! I have been in the vaping world for a couple of months now and I just bought the Ego One starter kit with the 2200 mah battery. It's voltage range is 3.3 to 4.2 volts as it decreases when the battery drains and it is protected. It is non-variable and it can support sub-ohm vaping 0.5 ohms and above. I recently bought the Kanger Mini Subtank with the RBA base. It came with a 0.5 ohm coil already built in the RBA base and it came with an extra 0.5 ohm replacement. I wanted to add the extra one it came with to the one in the base to make it a dual coils using the two 0.5 ohm coils. Would this be dangerous to my battery? I understand the battery will drain quicker but is there a chance of a dual coil setup destroying my battery?
