OnBoard Battery Charger

[Lucky26]

I want to install a onboard charger on my 12 X-35. Does anyone have any suggestions on a make and model that would be the best fit?

I have a Guest brand charger. http://www.defender.com/product.jsp?...16471&id=88417

Didn't buy it from the above link, but that's the one I have. Works great. Plug it in and forget it until next outing.

Do you have to disconnect the batteries or leave them hooked up and hooked together? Does your charger connect to both batteries? 12 volt 30 amp?

I keep a Tender on each battery. Leave the batteries hooked up, no problem .You can have the batteries wired parallel and use one charger or use two. I use one charger on my diesel engine in the truck (two batteries). It's an easy setup. Plug and play.

Yup that looks like the one I have on my X25. Boat was ordered with the charger/dual battery option. Works very well.

What happens when engine is running? Do have to disconnect each time you finish charging?

The one I use is connected all the time. It is totally automatic, determines what type of battery you have and digitally alters the charging profile to fit the specific type of battery. Once charged it just maintains them indefinitely.

I have an Optima Blue top and large Deka AGM Deep cycle set up with a automatic switching relay per the Diesel's dual battery thread. Bullet proof setup. Batterys are going on 5 years old and performing nicely.

Nothing. Typically you aren't plugged in to an outlet when running. Even if you were it would adjust its charging load to suit what the alternator is putting out. So basically it would shut itself down.

The following link is the "Official Dual Battery Thread". Follow its guidance and you are golden. I did the dual batterys with the switching relay. Perfection! Never had to get up and flip the battery switch again!

I also added a Bluesea Mini battery cutoff switch (quite nice, much better than Perko).

Due to corrosion induced resistance in the entire electrical system, I rewired from the batts to the distributor with all Marine Grade terminals, lugs, and wire, crimped, solidered, shrink wrapped (self sealing, and milspec on the battery cables).

http://genuinedealz.com/ Best place ever to get battery cable and connectors, will even pre make them for cheap, shipped quick!!! Prices are the best for the highest quality marine grade tinned copper wire and cable!

I ran 2/0 AWG main battery cables and stepped up every wire I replaced at least one size bigger.

Cleaned, de-oxidized, and applied Deoxit gold to every electrical connection every where. This greatly improved the voltages coming back from the dash through the ignition circuit.

I'm now getting 13.5 V at the coil while running vs. 7.5 v before.
