"Another thing to consider is what happens to your charger if you use it as a power supply. For example, you run your generator to feed your charger and motor the boat under electric power without drawing down the batteries. Not all chargers can handle this type of usage. Some chargers will believe there is a battery fault if they are running at 20A all the time. They expect the "batteries" to eventually get full and they apparently never do. I think Mike from http://biankablog. blogspot. com can expand more on this from his experience." I believe Jason is right about the battery chargers "going dumb" on occassion. I was doing some extended motoring using my ZIVAN NG-1 and running it flat out with the Honda 2000 providing power. At the time I did not have a functioning current meter so I was cruising along when several hours later I began to notice that the battery bank voltage was dropping but, the Zivan charger still had a green light. So I kept moving along. When the battery bank voltage hit 48 volts I figured there was some kind of problem. I disconnected the Zivan from the Honda generator and reconnected it and the charger started to charge again (red light = bulk charge). If I had a functioning current meter I would have noticed that the battery charger had gone into a fault mode much sooner and reset of the charger earlier which would have prevented the increased draw down of the battery bank. I have since been able to repair the defective current meter http://biankablog. Capt. Mike --- On Wed, 4/21/10, dwolfe@dropsheet.
