Re: Launching the Antminer L3+, World's Most Powerful and Efficient Litecoin Miner
For anyone running stock firmware, or not wanting to pay a 2% free forever on a simple mod, below is my tool to change L3+ voltage for free 
Its simple to use but requires basic use of ssh and command line. More info in the thread here: https://bitcointalk.org/index.php?topic=3546316.0
Since most boards come with ridiculously high voltage for the stock frequency (so bitmain can sell us stuff like L3++), you can reduce the voltage to the lowest setting on most boards, which brings down power consumption from 800 watts to about ~650 per miner.

Would you be able to write a script that does it automatically for some $. I have all my L3+ in a hosting facility and if I can lower the voltage by 10-15% I can save on my electricity bill up there ven more.
