system that is only 1 1/2 years old, with 40 Concorde Sun Extender batteries,
which are for the most part, shot (about half of them under 10V after a generator
EQ charge). Im sure the batteries have been abused at least after
the point that someone lowered the generator start voltage to 40V. Were
still doing fact finding on the charge parameters for the PV and wind, but Im
wondering if there is anyone that has an opinion on the Concorde batteries.<o:p></o:p></span></font></p><p class="MsoNormal"><font size="2" color="navy" face="Arial"><span style="font-size:
