How do you tap into a series battery pack to have the full series voltage AND half pack voltage from 2 parallel taps?
I have a 320V lithium battery pack (100 x 3.2V in series) that I need to tap 160V from to run a couple of heating elements with. The main 320V is needed to run a motor. I was hoping to have the 160V taps in parallel (50 x 3.2V in series x 2 in parallel) to keep the pack at a uniform discharge level while still being able to run the motor at full voltage and at the same time.
Is this even possible? Is there an inexpensive way to do it?
