Absorbsion Charging Wet Batteries

Gordon, solar trackers are cool but adding a panel or two is cheaper and much less prone to failure. So, no wager!

To gain any sense of perspective between charge regimen times the voltage must remain constant, 14.8 volts from the moment you flip the switch on to the moment you flip the switch off.

Skewing the results with variable voltages and non saturation makes time savings analysis worthless -- flipping a coin is just as inaccurate.

No variable voltages please and no cheating on the 14.8 volts.

Then and -only- then can you realize an accurate answer in perspective.

This is all about generator run time :)

Cost effective for outer space only.
For earthlings lower cost to expand your footprint.

Remember the stories about Rolls Royce, Jaguar, and Aston Martin? I don't know if they were true or not.

But it was a snotty reply

More than a golden hammer or toilet seat, typical DOD pricing.

And the price?

I wager he's working on a automatic solar tracker for rooftop RV install.

If I get 40 amps from solar, I am not starting a generator.

“in hopes that will get the batteries "full" before dark.”

What hopes? I’m full by noon usually...3 p.m. tops...with 300 watts and no pointing.
