Default Battery Charger

I have a 22' Grady with the full transom. Moved the batteries into the cabin 2 years ago (instead of the bilge). Best thing I've ever done, easy access, no water worries and best yet no crawling on hand and knees in tight spaces.
Now i want to install shore power and battery charger for the 2 Group 27's. Have read all posts on chargers and am sold on the Newmar phase three chagers. Will mount in cabin above batteries.
Question is, what one should I get? Below is the link to the specs. THANKS in advance.

Please don't.



Move the converter out of the direct path of corrosive / explosive gasses. And read the instructions. You will likely need fuse protection on each charging lead when making the connections.

What type of Batteries are you using? (Gel, Acid, spiral technology,AGM?) Because you have two batteries does not mean you have to buy a 2 bank charger. You can purchase a three bank charger without any problems. In this case bigger is not always better. You will need to anticipate how many amp hours you will use. In simpler terms, how many items will you power at one time (livewell, stereo, radar, windlass, Multifunction screen, external accessories, etc.) When you add everything up and you also anticipate your future needs then add 10 % and pick the appropriate charger. Do you trailer your boat or wet slip? You stated you want to add sure power, If you trailer and don't mine running a cord to a mounted charger you can save some money. If you wet slip and add shore power don't forget your galvanic Isolator.

Good Luck
