Made my first battery purchase, so many battery choices! I decided on 2 efest 18350 800mah imr and 2 mnke 18650 1500mah imr. Got 'em in pairs as I have read here on the forum its wise to have married batteries if possible.

I marked them with the date of their first charge (in my possession) and with an a & b in case one holds a charge better, gets hotter etc. (ocd I guess). Should I have used a sharpie for this? I picked middle of the road, not the most expensive or the cheapest. I also picked what the forum says could be used in either mechanical or pcb controlled devices. They say the orange ones are good for the mechanical I am waiting for (a cheap m16 or v2...I think, need to check the store site as its been a while HKP...go figure
). I don't want to spend a lot up front just in case I find I like my variables better. Opinions...? Criticisms...? Between my wife and myself I bet we've dropped almost 3 bills on vaping in Dec.! I LOVE VAPE MAIL! Surprise vape mail is even better...
