[RE-wrenches] Hawker versusu MK

[Ray Walters]

Full River has better cycle life specs for a sealed battery.  We've 
gotten good feed back from the field so far.
B&B is another that I've abused and had good luck with.  Their cycle 
life is lower, but comparable to the Hawker or MK.

In it, I  use a combination of Rolls-Surette and batteries made by Crown Battery in Ohio.  The Rolls serve as the primary batteries for the main inverters.  The Crown batteries provide power for three portable solar electric systems ranging in size from 1 to 5 kW (with Exeltech sine wave inverters attached.)
