NOTE: I say in this video "Charge miles per hour". I meant to say that for each hour of charging, I want to charge at greater than 1 hour of travel. The miles per hour is times 4, assuming 4 knots travel speed.

We're back to angry pixies! In this video, I replace the old Victron Quattro 48/5000/70 for a new Multiplus-II 48/5000/70. I talk about why I switched, and what the differences are between the two models. Then we get it setup and charging the batteries again.
