one of the #1 rules of vaping, right behind "have backups for your backups" is a law on batteries. NEVER buy batteries from an E-bay dealer of whom you do not personally know &/or TRUST, either completely/personally, or through a 3rd party, like a reviewer on ECF such-as myself. i DO NOT recommend EVER buying batteries from E-bay, although there IS a few reputable battery dealers on Ebay... you simply cannot afford to play the dice when it comes 2 batts. you cannot afford to skimp on the batteries. I skimp on almost everything BUT the batteries.... I buy the cheapest mods I can possibly find. I even buy the cheapest JUICE I can possibly find- in fact, I'm usually vaping on plain-old bulk nicotine, with 3-4% RY4 flavoring added to the mix bottle. As-far as batteries go, I have ALL Efest and AW batteries, other than one Panasonic that I got with a mod-kit a while back. I even skimp on battery CHARGERS!! NOT batteries!
I recommend you ONLY use those batts in regulated mods, and, if you've used them in single battery mods AT-ALL, prior to using them in your RX, then I suggest you stop using them in the RX all-together and rather continue using them in 1-battery regulated mods only. You MUST devote a set of batteries to a mod that uses 3 batteries parallel. You CANNOT/SHOULD-NOT USE batteries that were used in other devices, in your 3 battery mod. u MUST devote a set to your RX 3 battery mod, or, buy two sets of 3 and devote all 6 for use in THAT MOD ONLY! This will prevent any 1 battery from stressing more than the others, this prevents 1 battery from draining faster than the others, etc/cte....

be-caaareful when it comes-to batt-safetyyy!!! It's the ONE, SERIOUS thing, that us vapers actually HAVE TO ABIDE-BY and LISTEN-TO! KK? KK. Have fun, and, ENJOY your vaping journey my man!! Enjoy it!!
