I bought the new BVC coils yesterday and from the 3 that I tested, it flood very often every time e-liquid goes under the 1.4 ml mark on my Aspire ET close to the top of the coil. There don't seem to have this effect with a full tank yet (it was completely full, now at 2.4ml mark). I get a gurgling sound and vapor production decreases, the battery gets e-liquid too. I need to blow in the drip tip and clean the battery. I had to do this about 15 times in 24 hours. The liquid I use is 70/30 PG/VG. I had no problem with the BDC coils with only occasional flooding.
Is it a common problem with those ?
