Cydog15 is getting info about bestconverter's "Boondockers", while I have been talking about PowerMax itself. Not the same, as I have also tried to point out.
On the subject of time in boost, IMO it is hopeless to have a fixed number for the automatic stages mode, since one size cannot fit all. Each designer will pick a time out of his hat, and that's what you will get. It could be a different time and voltage in different models, so you have to read up the specs before you buy a particular model and boost voltage. You must not confuse "Boondocker" with PowerMax either--different companies. Last I heard, PowerMax supplies Randy with his Boondockers to Randy's specs.
PowerMax has added the nifty feature of an adjustable voltage that stays at that until you change it for its LK models. ( Randy has gone with that for his too) So you can charge your batteries just right for your situation.
