Battery Charger system

[Bloodweiser]

Looking to add a charging system that monitors,maintains both my batteries. Currently I have to charge each battery separate with the charger that I currently own. What are you guys using ? brands preferences, what should I look for/avoid.
Goal is to plug in and walk away.

thoughts??

I have a Guest 20 amp, 2 battery charger in 'MyOtherBoat". I don't know if it is the best but it works fine for my boat. It was already in the boat when I bought it.

Mine is 15A with 3 channels, designed to monitor and peak charge each battery separately - so it has 6 output terminals. I will look at it tonight when I get home and post the make and model.

I have a ProNautic 50 amp charger with 3 banks. Does a great job maintaining my batts.

I've always been a fan (and user) of ProNautics. I have lot's of experience with Pro Mariner, going back a couple decades and literally hundreds of these (between my own boats, family/friends and customers). Good track record and excellent customer service. This is not to say they are the "best" as I really don't think there is such a thing - it's more about what's best for your situation.

ProMariner has worked for me for many years. Charges 2 batteries and maintanes them on my 232 Gulfstream

Check with ChargerGuy on THT, he sells refurb units. Mine came from him and was a great price, very reliable (have 5+ years on it now).

ProNautics 12-60 charger for six AGM batteries, works perfect going on two years .

Mr Crab, Whats on the floor? It almost looks like carpet but I'm sure it isn't. That space is way too clean!

 

[dogdoc]

ProNautic is the way to go. Easy to use, good documentation. Just try to mount where it is easy to see led readout

Mine is ProMariner ProSport20 Plus...3 bank charger. I charge 2 separate start batteries and a House Bank of 2 batteries in parallel.

It looks like they have made some model changes..calling them "HD" now

 

[Mr.crab]

Lots of elbow grease, since I made a anchor locker and sealed everything no water gets in bilge

I installed the NOCO Genius based on personal recommendations and a lot reading THT, West, etc.

Easy install, small footprint, and idiot proof indicator lights.

On the cheap end. I just use a simple Battery Tender for my dual battery system. I set the battery switch to both and it keeps both batteries topped off. It's only 2 amps total I believe but it will keep both batteries charged and happy in the offseason. Not mounted permanently.

NOCO Genius GEN2 - 20A 2 Bank. NOCO and Promariner are good products; get whatever has a better sale/deal going.

Consider a “smart” charger/maintainer with individual outputs if you’re running different types of batteries for starting/house loads.

 

[Bloodweiser]

thanks all for the replies. I purchased a promariner 20a 2 bank charger from PartsVu

Check with ChargerGuy on THT, he sells refurb units. Mine came from him and was a great price, very reliable (have 5+ years on it now).

looks like Chargerguy has retired from the battery charger business.

 

[Fishtales]

lot of good ones out there...
I have 4 batteries, 2 banks and the stock unit was a 15a Guest. A lot seem to only be 10A per bank now unless it is a larger unit. ProMariner, Guest, Minn Kota, Genius all pretty good. I'd look for one that fits the space you have.

 

[Lsquared]

I contacted Grady to see what they are currently installing in the case of the battery configuration. 2bank 3 batteries and they suggested promariner 36 amp 2 bank. Picked it up on amazon for under 400 and am installing it this weekend

 

[Fishtales]

sounds like a plan. good luck with install.
