My Charles 20 amp, 3 bank battery charger died in my 99 310DA. I'm pretty sure this is the original charger, but I could be wrong. I need a 3 bank, but I have no idea what to replace it with. I was thinking of getting the same one as they still offer it, but I want to have a screen or some type of monitoring system for my batteries either on the battery charger, or a remote panel type. I'm fine with either, but no clue what brand to get. I noticed that ProMariner is affordable, but almost too affordable for a 20 amp, at only 199.99 whereas others are $300+ Can anyone recommend one? I run a robust sound system that all operates off 12v. Thoughts?
