These coils don’t require as much power to heat up and don’t get as hot as their Sub Ohm cousins. Because of this, thinner E Liquid is used so the coil doesn’t get clogged up too quickly. We recommend using a thinner High PG E Liquid like our 50/50 E Liquid (50% VG to 50% PG).Aspire BVC Clearomizer Replacement 1.8Ω Coils– Recommended 4.2-5.0WIf you want to know more about E Liquid mixes and ratios, have a look at our E Liquid Guide.
