HYP...I just read the smartguage site and it is for 12V banks only.
CharlieJ...I also think that they greatly overstate the issues with shunt based amp guages as I have experienced none of the issues they claim "shortly" affect the guages. Yes...you have to reset them...yes you have to enter the right Peukerts data etc. but if you follow the owners manual they work damned well. I know nothing about the Smart Guage Algorythms but given the # of software
updates they have had...it seems like keeping up with ALL the latest batteries and specific data is a chore for them. I would be reluctant to trust my battery
bank to a formula that does not rely on actual measurement of amps in and out and only tells me that it is 70% charged...but does not inform me that the 70% charged is compared to a battry that is only 60% capable as a new one of holding a charge....or 42% of ORIGINAL capacity rather than 70% of current
I can be convinced...but I'd sure like some actual unbiased testing on this side of the pond to confirm that the device works as advertised with a variety of different battery
brands and types found here in the States.
