Thanks for the detail on how to start the MM with this kind of voltage. I got my DeWalt pac Fri nite and have harvested the cells. I'm doing something very similar, but using a 540c 9xl and was trying to decide on what to make, 5S1P was what I wanted to do initially, but was just about to decide to try 4S1P since my charger can handle that. Think I'll stick with 5S1P!
