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

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

looks like Chargerguy has retired from the battery charger business.
 
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.
 
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
 
sounds like a plan. good luck with install.
