As you can see, I am not much a mechanical whizz.
Is that blue thing what your using to charge, or just take readings after your plugged in to shore power, and your converter is doing the work. The best charger you have is your on board three stage converter to replenish your batteries. Use that and you will get the best results. That will also eliminate the possibility of boiling your bats, in case the blue thing isn't "smart", and can't sense state of charge during the process.
