Maine Sail, you mentioned the Smart gauge in another thread and I didn't want to hijack. I recently saw an ad for this and when I checked the spec sheet apparently there is no shunt and it looks like their software calculates Peukert?? Normally I wouldn't have given this much thought, but given it is from Balmer, it peaked my interest. Although I already have a Victron, always curious about new products. You seemed to indicate that you were impressed with the monitor in another thread and would love to hear more of your take on this thing....
