Ok back on topic. My goal is to maintain two 6v 208ah GC2 batteries wired in series. They will have no loads on them over the winter and will be fully charged and desulphated before being put on the charger.
My plan is to use one of these: http://www.amazon.com/Battery-Tender...y+tender+solar
It will be connected to a 15w solar panel that will be mounted due South and almost vertical. Probably 75-80 degrees.
The BT solar float charges at 13.2 volts just like their standard chargers. In good sun I should have about 1.25 amps of charge.
I tested my 15w panel with a good voltmeter. Even with clouds it puts out over 13v. Full sun and its about 14.7v.
This should work just fine or am I missing something?
