About Me

- I was a PSD Board of Education member from 1999 to 2007, and spent nearly 3 years as its president, from 2003-2005. I represented Fort Collins' District 5 as its Councilmember from 2013-2021, serving as Mayor Pro Tem in 2021. In my private life, I'm an engineering manager with nvidia, a computer chip design company, and I am a board member of MLCommons.
I have converted two cars from gasoline to electric. Past hobby computer projects include Hoverball and Adventure Definition Language.

Ross: Reading about your HIGH VOLTAGE signs reminds me to warn you, and others, about the EXTREME danger from "Arc Flash." Possibly you are already aware of this situation, but maybe other hobbyists are not and would benefit from this note.
Because of the high DC voltage and very low impedance wiring, an accidential short circuit (such as dropping a wrench across a battery terminal) can cause an EXTREMELY VIOLENT explosion with molten metal flying in all directions. Serious injury would likely result.

Best regards for a safe project.

Roger, yes, thanks. I'm familiar with arc flash, having experienced it at 144V (and having the outer layer of skin blown off the entire area between my knuckle and the first joint of the middle finger of my left hand). I have no desire to experience it at 312V.
For safety, I plan on separating the batteries into three sub-packs of 96, 108, and 108 volts, using CamLock connectors to separate them before working on the packs.
Mr Ross Cunniff, can you post some videos off you driving this jeep ?
Please ? My email it's miniUMM(at)gmail.com
best regards
I have one video on youtube - when the weather warms up more, I plan on making a more detailed video tour.
