Thanks for the insight. Our initial testing was using the 12 volt chassis battery without any of the lithium packs or the controller powered up. We just received the new boards today and will connect the 12 volt "chunks" of the pack tomorrow.
I was hesitant to trim the voltage using the plugin but you have put me at ease. We will dial each block in comparing to our multimeter and see how it behaves over the first few charges. Our first debut show is this Friday.
