And the 2 or whatever people that ordered will definitely get a free one of the board that will be out soon that will fix the low voltage cutout. Sorry you guys. It was a subtle mistake. The only reason I noticed it was that someone emailed me asking about how the low voltage cutout works, and I walked him through each resistor and transistor. As I was explaining how it worked, I realized I made a mistake.

The good news is, the board as it is right now can be used as an SR board (with 1 safety feature not working), a standard control board for a motor controller with all the safety features working, or as a control board for a charger with all the safety features working. It also has CANbus, and stuff, so it's not complete crap. So you couple guys that preordered it, you get a free charger board (or whatever you want to use it for) AND a SR control board (slightly delayed)! hurray!
To resolve the omission of controlling the 2nd LV cutoff is necessary the addition of extra parts? and if so, can this parts be top mounted in the board for this first PCB release?
