Hi there. I have a few questions about "safe" batteries to use with my new istick pico. I ordered the LG hg2, Samsung 25r and a LG hb6. The last is a 30A and after reading some other posts on this site, I'm concerned that the hb6 may not be compatible/safe with the Pico. I plan to use 0.5 ohm, 1.0 ohm & 1.8 ohm coils. I don't want to hurt myself. Any advice from experienced vapors will be greatly appreciated. Thank you in advance to anyone who replies.
