I have to replace my battery charger, any recommendations would be appreciated. The boat is a 310 DA. I have four batteries consisting of two banks as two batteries are hooked up in series. No generator. The existing charger is a 30 amp. Intell-power which was designed for three banks hooked up as two banks. Inside the unit Sea Ray used one connection for one bank and tied the other two together for the second bank.
 
I think a lot of us have replaced with a ProNautic. If you have a 30 amp now, it’s easy to go back with the same 30 amp as if you go with a higher amp version, you may need to upgrade the DC wiring and the AC wiring and breaker.
 
I changed mine out to the ProNautic 1240. Seems to do the job fine.

I also have the ProNautic 1250, but I changed that out ~8 yrs ago. It has some draw backs in that the remote display does not display the banks only the total voltage output (highest bank) and amps etc. are displayed. If I were to get one now I would go for one of these: https://www.mastervolt.com/products/chargemaster-plus/chargemaster-plus-12-35-3/ (The 50 for me) many more features and expansion possibilities. But it also has NMEA2000 and supports the battery status that many mfd's now support. And also power supply mode that doesn't need a battery present.
 
Thanks SKybolt, I see your points on Mastervolt, however I already purchased the Pro Nautic. I'll be installing it in a couple days. Maby you or one of the other members can answer one question I have on the programming of it. On the unit itself it has profile one and profile two. In the programming section under "selecting battery type" there is no mention of it. Am I over looking something?
 
That confused me as well. I just use profile 1 and set my battery type as appropriate to what's installed. I was never clear to me which settings were tied to any given profile.
 
Thank you for the quick reply. I will get in touch with pro mariner and post what they say. I had the same charger in my last boat, 2015 Four Winns,, which came with a start battery and dedicated house battery house battery. They set it up as one bank with a voltage sensitive relay so I never thought about the second profile.

It's a great charger, as I mentioned I have the same charger. With regard to profiles they are simply the battery type and a selection of charging voltage range. Setup and operation is on pg 16 of the manual. Simply select your battery type and preset 1 or 2 for voltage range. I don't really see the point of the ranges as they are very similar, but an engineer at ProNautic seemed to think it was necessary. The "Profile" they refer to is the battery type and selected Preset of voltage.

Thanks again SKybolt. Saves a lot of phone time. I did'nt see the two profile selections on the User Selectable Battery Types chart. Like I said in last post I had this charger on my previous boat and never really under stood it. To me the 310 is a lot of boat and I don't want to make any mistakes. All in Club Sea Ray are really helping me out.
 
Installed Pro Nautic 1230 as two banks. Easy swap out and works well. Thanks all.
 
So I am going to resurect this older thread, rather than start a new one. For those of you who replaced the stock Promariner with the Pronautic, how plug and play is the install? I am going from old 30 amp to the new 12-30.

Looks like the mounting hole pattern is different. Did you fill the old holes with epoxy or anything? Did you use any sealant on the new holes?

Wiring looks all set -- 3 AC, 4 DC. Was there enough extra length to get everything hooked up and the charger mounted? Are the ring connectors the right size for the terminal studs? I am a little concerned about the bonding wire -- it looks short.

Thanks in advance.
 
On the 310 da I had to replace the ring connectors and extend the bonding wire. Since the old charger was on what appears to a plywood sheet I just pre-drilled holes and set it with new screws. Job took about an hour. Its a good practice to re-do the connectors. Also disconnect your batteries and shore power.

Completely wrong application for a Noco anything. This is a boat with full time DC voltage needs for lights, pumps etc, so it needs a charger that can also be a DC power supply. Noco can never be used in this application.

what full time DC usage would a Noco not handle

A Noco is a fine light duty charger and maintainer. But it's literally 1/3 the power of the chargers used on these boats... and in some cases 1/5 the power. And that's for the single bank charger. Their multiple bank chargers supply only a small amount of amps. Again, a fine maintainer or light duty charger but the ones being discussed are in a different league.

Also... is the Noco rated to be installed inside a gasoline boat's bilge? The chargers being discussed are setup to be hard-wired and are ignition protected.

Bigger boats require different equipment.
 
Well I am happy with my ProNautic. I little bit more of PIA than I wanted, but I got it. Biggest issue was the bonding wire -- just not long enough, and went thru a few sized connectors until I got the right one and it worked. So far, running well.

ah thank you makes future multibank charger purchase easier
 
one question is the 1240 40 amps per bank or 40 amps spread over 3 banks making it not much more powerful than the NOCO never mind I researched it
