Battery charger system - ProMariner

Hi,

is anybody using the ProMariner dual battery charger system?
For example this one: https://www.amazon.com/ProMariner-43...rds=ProMariner

- Is it possible to even uncharge the baterry while charging, using a refrigerator or the receiver?

Can a load exceed the output of the charger? Sure. These are not power supplies, so they are not intended to used in a continuous supply mode.

I have one on my boat and it works great. What's the power draw from your accessories? Over 20 amps and the charger won't keep up. Under 20 amps and it will still charge the batteries, just not as fast.

I have that same one in my boat and it works great and I'm running Optima Blue top batteries. That charger has three settings depending on the type of battery you're running.

Just a quick word on this. i have had pro mariner chargers on my bass boats. I have had a sketchy history with them. I know i am not answering your question, but it seems others have as well. They used to be big in the bass boat market. As a fisherman with a bassboat, my trolling batteries always need to be charged. After a few years of failures, i went with Guest chargers and Dual Pro.. they are just a step above most chargers and are designed for harsh marine environments.

thanks. I think we re going to insall one at the end of this season

Because right now the situation is that we disconnect both batteries at the end of each season to make sure that they do not discharge to much.
I think that it is even a god idea when we sleep for one or 2 nights at the boat in a harbor for exaple with runing refrigirator and so on.

Does your dual bank setup not have a main battery switch? Turning it off, achieves the same thing.

The manufacturers dont. As stated above, these on-board chargers are not power supplies intended to keep pace with continuous loads. Just note that the frequency of this and the amount of the load, can impact the chargers life.

Yes we have one.

I just measured that even in off position there is some current consumption, do you guys all just leave it switched off without disconecting the batteries during winter time?

- but isnt it the same thing that the alternator does when running the boat?

I leave the batteries connected during the winter.

I have that charger on my boat and it does a great job maintaining them.
