Hi Ben,
I'm using an Elcon PFC 2000+ 48V charger that has been programmed for my Lithium battery pack. The charger has big heat fins and a built in cooling fan. As a charger, it has all of the appropriate programming to prevent overcharging if the batteries get full. The charger will push a consistant 28A at 54V (over 1500W) and has worked very well providing power while underway. The charger does pull a maximum of about 14A of 120VAC (almost 1700W, measured with a Kill-a-Watt meter) which is above the continuous output rating of 13.3A on my Yamaha EF2000iS generator, however, the generator has always been able to support the charger demand. The longest that I've run in this mode is about 90 minutes.
So my experience is that the Elcon chargers work well as power supplies too.
Fair winds,
Eric
