Battery charger replacement

It's a max of 40 amps and can distribute those amps as it sees fit. Meaning, it's possible for one battery to receive all 40 amps. That's a huge difference over the Noco.

But, let's do some math and pretend that it is giving 13.3 amps to each bank. According to Noco's website, their 2-bank charger can give up to 4amps per bank. The PM is 3-1/3 times more powerful. Again, according to their website, their 4-bank charger can give up to 2amps per bank. The PM is over 6-1/2 times more powerful. I don't know about you, but I wouldn't call that "not much more powerful". And, again, that's if the PM is equally dividing the power.

Unless you're trying to compare the single bank Noco which has 10amps? That's closer. But it's still not a built-in charger/power supply.

Besides, who wants to be attaching alligator clips and have an extension cord laying across the deck as a tripping hazzard. It's good for a battery that is removed from the boat - but it's not meant as an onboard charger.

ok gotcha yes that would make a difference but really the biggest is the DC power (I guess it also acts as an inverter which is what I do have on my little 220 DA). thanks for clearing that up big difference even if the other is cheaper it doesn't do what i need it to do

Nelson, just to be clear, I wasn't using "big boat" vs "little boat" in a diminutive way - it was only to clarify the part about, typically, having more systems and also that these are "more likely" (than a smaller boat) to stay in the water hooked up to shore power where one would only want to plug the shore power cord in and then walk away.

That said, if the Noco does what YOU want... then that's all that matters. If was me, though, and I was set on using the Noco, I would figure out a way to connect the charging leads permanently (ring terminals) and extend them so the charger, itself, is NOT in the engine bay. That would at least make it safe and easier. A small charging outlet installed in a convenient location would be good, too.

I wasn't offended and you saved me buying the wrong charger thanks

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 know this is an old thread, but figured someone looking to replace their battery charger may take a look at it. I came across a spectacular deal on the Promariner Pronautic series of battery chargers. I put a 1230P in my 370DA a few years back and am very happy with it, so even though i don't need one i picked one up anyway. At this price you can't go wrong. I have purchased from DelCity previously so they are legit. I have no idea why these are priced so low.

Hope this helps someone.
 
I was also looking at the NOCO 10x3 for my 370 as a replacement to the OEM unit. Not sure I understand the 'power supply' reference mentioned. From what I read the power supply mode is for when a battery is not present so not understanding that bit. The NOCO splits 10 amps across each bank output so why would that not be enough if the boat uses battery pairs in parallel for each engine as well as a single batt for House?

I am an idiot with electrical so dumb it down for me. I am about to install the NOCO this week but if someone can explain why the ProNautic unit is so much better I am happy to buy that instead.

Hello 370. Good/fair question. However, we already discussed that answer up above :) Please read through those other posts - if there's something that doesn't make sense, reference the specific thing that doesn't make sense and we'll be happy clarify.
 
The new 10x3 Noco units are wired direct same as what is there now. The notion of the 'power supply' is what I am unsure about. My 370 has an onboard inverter for AC but the House battery would also supply any standing DC needs.
