In a recent thread, there was some mention of 24v float charging for house and coach systems. Since my house system is 12v and totally separated (12v alt, 12v inverter/ charger), I need to maintain my new coach 8Ds this winter. And for the first winter since getting into bussing, I can keep the bus plugged in... and
keep those 150# beasts in
Anyways, I need to purchase a little automatic charger/ maintainer for the coach side. I went to batterystuff.com and see a bunch of 24v chargers. Some are made for 12v batts in series (like mine), that can charge each batt separately. Or I could use a single-lead 24v charger that floats at 28v or so. Any pros/cons for these two distinct methods? I figure my coach alt. puts out a 24v nominal voltage that the batts use to charge themselves at 12v nominal. So floating batts this way seems OK in my mind... but I'm no expert. Here's a charger I'm looking at
I could also move the cables to parallel them and just charge the set with a 12v charger... but would rather leave the batts "good to go". Imagine forgetting to switch 'em back and trying to start the coach on 12v.
I could also pony up for a Vanner equalizer and use a 12v charger on it's leads... but probably won't do that right now. Eventually, I'd like to buy a mongo 24v inverter and use the coach alt. in parallel to charge house and
coach side... but not anytime soon.
Any thoughts? Thanks,
