I'm looking for something that has the automatic input voltage adjustment, automatic shut down and I can move between lead acid and lithium easily. Also, a cost less than $400 would be nice.
I have a K&W BC-20 right now and it's a great charger, I just wish it shut down when done. And provided more power, I have access to 120 volt and 220 volt plugs but don't have a charger capable of handling 220v. Yet.
