Do you need heated grips and heated gloves? I don't. The gloves work great for me.
What layer will you wear over the heated liner? A very warm, thin layer like a Primaloft coat or a thin down sweater, even thick fleece, greatly reduces the heat controller setting and the electricity used. Keep your head warm with a thin fleece or wool helmet liner or balaclava. The body sends warm blood to maintain the brain and core organs while depriving the extremities of warmth if necessary.
The heat controller doesn't dump electricity. It rapidly switches on and off, must faster than a half-second for the ones I've used. Yes, your assumption about 100% draw then zero draw for time periods is correct--longer on & shorter off at high settings, shorter on & longer off at low settings. Your battery, any type of battery, buffers the power draw. The lithium iron phosphate batteries (Shorai) are smaller and lighter, may live longer, self-discharge more slowly, but not sure that they're worth their cost, $125-$160.
