Any advice?.. i'm finding it difficult to find tutorials using 4 batteries.. I'm debating on using 4 in parallel or 2 series ran parallel. I found some diagrams to show how to wire it in series or parallel with a mosfet. I am wondering if i can run it with 2 parallel series and place a resistor to drop it to 5v or 6v. unless using all parallel would yield more power.

Also wondering what would be best. I want to build a high watt mod but the chips are out of budget for the time being, other than the okl-t20 but the wiring diagram i found in the guide is hard to read for me. I need a simple tutorial because i'm new to building.
