Daves,

This is all a possible calculation. If you know the battery A/20 (ampere hours for 20 hours to 10.5V terminal), you can look up the equation to find out what the battery can do with a higher discharge rate. Look up Peukert. He figured this out long ago. Lead Acid batteries have to circulate the electrolyte to preform and that is the slow down. I don't have time to link this all for you today, my wife's car has electrical problems.

Thanks Matt. I think i've accounted for all that but i work in aviation. No matter how sure you are, have someone check your facts. Smile
