I have 3 mods that use three batts, one 26650 mod and my well used dual batt ipv4..
I get almost 2.5 days on the 300w Koopor Primus vaping the same CloudBeast .15 ohm coil at 125w
Like I said earlier I get about 1.5 days on both the RX200s and black RX200..
I've heard other folks having issues with the RX200(s) but fortunately I'm not one of them..
I don't run TC so maybe that's why they have performed so well for the last 4 mos vaping them in rotation everyday...just my 2¢
