Adjustable Voltage Boondocker Converter Question

This BATTERY DESIGN ENGINEER says you are incorrect power guy. I designed them tested them and trouble shot flooded LA batteries. You folks on the charger industry talk to APPLOCATION ENGINEERS at OEM. Not the guys who do the chemistry and alloy work. I sent a pair of incredibly polite emails to Randy and he never bothered even to acknowledge them. You chose to argue with jouneyman while ignoring my question. You and many others in the RV converter manufacturing business need professional assistance if you are EVER going to produce a charger unit that does not chronically undercharge deep cycle batteries.
