Advise needed for on board charger
 

I am wanting to ad an on board charger to system.
Currently have 5 group 27 batteries.
1 battery for boat electronics/starting.
4 baterries for stereo. 2 (Parallel) A... seperated by perko (2 more Parallel) B..... or.... ALL
Setup with 200 amp relay to connect the 1 battery for start/electronics. to either A or B for charging when on water.

Question? If I get a prosport 20 3 bank will it work? And would it be hooked up? One lead goes to start, one lead to 2 batteries A and one lead to 2 batteries B?

Hope I didnt loose you in the explanation of setup

Is prosport 20 the charger that is best for this, or is there something better?

Thanks again

Tjay,
In this case either a 2 or 3-bank charger will function the same. Assuming that you have five batteries because you are going to regularly deeply discharge four of them, I see problems. With 375 amp/hours of collective capacity you need a 40 amp charger. You could run a 20 amp charger into the ground and you aren't supplying the current needed for the batteries to properly desulphate.

Thanks for the info
What would a good 40 amp charger be?

This one would not be a "good one" it would be the "best one"

Give them a call as they do have refurbed units for a significant discount.

We use the Inteli-Power chargers for anything larger than 20 amps. They come in 30, 40, 50, 60, and 80 amp models.
