Question: what to do if you drop a battery and only need a 2 bank charger
Document: Perfect for 24V systems. Super easy to install and the three levels of charging (including maintenance charge mode will be perfect for off season storage. Best part is that I no longer have to switch my old deep cycle charger to each battery, taking hours to get all 3 batteries fully charged. A little more expensive than the 2 bank chargers, but definitely worth it!
First the price very competitive, second the 6 ft long cables which allows to reach the cranking battery which is on the other side of boat from other 2 so allows flexability to where it is installed. I also like the lights that show when charging is in progress and is done for each bank and if a  connection may be loose.
1)The battery cable connectors are so big and are unibody. I had to cut a big hole in my wall between the battery compartment and dry storage for the charger. There is no way to dissconnect and slip small cable through my existing hole that my Bass Pro used to fit through.2)The plug in part of the charger is a regular three prong plug that comes with a cheesy plastic clamp that you are to hang plug in when not charging.
good charger all boats need one
Had worse day fishing ever. One battery was dead (which I thought was charged) only had 12 volts on 24 volt system. Trolling motor would not hold in current we were fishing. Came home, ordered this 3 bank system, couldn't be more pleased. Come in, plug in charger, forget it.
Works like a champ,was going to go with the 2 bank but after a little struggle running wires glad I went with the 3 bank,instruction very easy to fallow, its peace of mind knowing that when I hit the water the last thing I have to worry about is my batteries.No more lugging around heavy batteries.
I have this installed in my 1996 19 foot Ranger flats boat. I have a 24 volt trolling motor, so I use all three banks. Two banks connect to the two 12 volt batteries used for my trolling motor, and one bank connects to the battery that starts my 2011 Mercury 115 Pro SX Outboard Motor and also runs my GPS, Humminbird Sonar, and other electronics.
this is a nice unit. I have one bank keeping trickle charge on my generator, another bank keeping an auxiliary battery charged, and the third bank I made an extension to be able to charge a scooter or car that I pull up in front of the garage door. pretty useful with indicator lights showing charge status.6/1/2013  Update and rating changed. Unit didn't seem to be charging batteries.
I had a MK 10A per bank charger that lasted for years and wanted to replace it with the same, but for whatever reason the new MK 10A, 3 bank charger was larger than my old one and wouldn't fit in the old space , so I had to settle for the 5A. Installation is easy and it works fine, but it's alot slower than my previous. Needs about 12 hrs for a full charge.
Each bank has its own light. If there is a malfunction or the bank is not working, the light is red. I rarely look at the lights because I would have to lift up my seat to see inside where the charger is mounted. However, sometimes I want to see that my batteries are being charged so I have a look.Generally on return from fishing, I just plug in the extension cord and forget about it. It easily recharges my batteries overnight.
