good afternoon,
may sure you tell them how many mls you use over that 4 hours. Even though 10 watts and 1.5 ohms isn't going to go through that much liquid, it still may be helpful. for my usage (5-8 watts at 1.8 ohms) i go roughly 1 ml/1000 mAh. so i get 2-2.5 mls between charges (and i don't fully deplete the battery) . i always have several PVs going at once, so hours of charge isn't easy for me to figure.
I'm assuming that if it's not "defective" they're return the one you sent in?
I guess, CES, they didn't say. But I believe it IS defective, as I probably use 3ml per charge. Maybe a little more.
