Further to my earlier post in Jan -Feb of 2107 in discussion with a installer he noted the battery's were being changed out because of a impedance problem in the stacks and in discussion with another installer recently in mention the same problem and same result , now I don't pretend to know anything about electrical impedance its causes or remedy's but I am sure there are people out there that can explain this . The point I am making is the problem appears to have been around since early 2017 and is still occurring up until recently. Redfow didn't report a problem until April 2017 .It would appear that this impedance cant be fixed by any of the methods mention by Redflow and they are changing out the battery's as a remedy and sometime on multiple occasions for the same installation as in ND set up. What I do understand is that impedance may not show up until the battery's has been running for some time and I think the test for it is a mega test I sure someone can put me straight on this . But as shareholder I would be very disappointed if Redflow were sending out battery's and weren't sure they were good to go and waiting for a customer to point out a problem .
