Ken thanks for sharing. Good to hear that the battery helped.
I have been shopping batteries for awhile and have a friend in the
solar supply system. They sell Deka's and have to check almost daily
before they can give a quote on batteries as the price goes up
frequently because of both increases in lead prices and transportation.
One thing I found was that so far when you go for 13 most suppliers
will drop ship them at no cost.
I found a deal on some "slightly" used grp 27 agm and will see how
that goes over the next month or so. It is sort of a test run for our
local EAA chapter. Haven't put them in yet, still enjoying the gels.
I'm anticipating some balance issues with the agm; time will tell.
My gels have 23500+, a few in there starting to show their age. The
Paktrakr has them well identified.
