so just to confirm... yes TC is draining my batteries faster.
two of the top tank mini v4 RBA (both with 28g SS316L round wire 5/2.5 coming out to .5 ohms)
pair of top tank mini's so approx 3.5 ml of juice per tank
same 3 mg 70/30 VG/PG juice
Double Trouble
pair of kbox 75w minis (one set at 23w the other at SS 420f/75w)
a married pair of VTC4's(from my 160w dripbox, i bought them 3rd week in nov they're fairly new, so they would match as best as possible)
i did not change my typical DtL 3-7s puffs alternating with my usual chaining quick 2s puffs.
i went until each hit the last bar on the power, going by juice amount left... with TC i got 3/4 of a tank, with watts i finished the tank and almost 1/3rd more.
so while i can see the value of TC with what it does, and i will use it on occasion, wattage will still be my prefered when out and about for keeping my batteries lasting longer.
