No sure about the 4 bank...I'm sure someone's gotta make em...and you'll pay for it i bet.
Minn Kota makes a quick disconnect for their PowerDrive and Autopilot TM's. I had one mounted for my PowerDrive, LOVED it. 1 thumbscrew, and the sucker was off. Mounts in a REAL small area too, so it'll fit pretty much anything. The mount was like $35 from what I remember.
I have a 4 bank charger I got this year, have not installed it yet, plan on doing that in the next week. I cant remember the brand but will look when I get home tonight and post it for you. I do know I got it from Cablea's and it was a little pricey but a real nice looking unit. Heavy gauge wires, and each charger bank has its own fuse. I will post the brand and model tonight...Stretch
The one I have has four different sets of wires coming out of it. So you connect one set for each battery. Really nice setup, and the charge rate is fast, just wish I could remember the brand , oh well I will post it here once I get home and have it in my hands. I was also surprised at the size of it, not near as big as I expected. I will post more about it later once I have all the info in front of me......Stretch
I found the charger, just happened to have a BPS catalog here at work
The charger is a ProMariner and the model I have is a ProTournament 300Quad. It lists in BPS for $400.00. Hope this helps......Stretch
It doesn't matter how they are wired. You connect to each battery, if you have 4 batteries you connect 4- different sets of wires to the batteries. 1- positive, 1- negitive to each battery. Very simple, even you won't screw that up if you follow instructions. It's been done that way for years, and years. just because they are wired in series to equal 24 volts, the charger only charge 1- battery per connection.
