How many charging amps do the cteks provide?

Matt, the Ctek 3300 is 3.3 amps. David of Earmark Marine said these chargers are actually underrated, have sophisticated technology, perfectly suitable to maintain a single battery such as a starting battery. In my application I had a Promariner charger from my previous boat that could maintain 3 batteries (2 stereo, 1 starting) but when I added a 3rd stereo battery due to multiple transom LEDs and interior LEDs David suggested that I just put all 3 stereo batteries on the Promariner and just add the Ctek for the starting battery.

The only thing is they don't make multiple bank chargers. I bought two for $120 on Amazon.com. The guy at a local battery shop recommended them, but he wanted $79 for one.

They have some very positive reviews and looks like they'll fit just about anywhere. Throw up some pics when you get them done-

Any thoughts on using one of these chargers. I have one and Im thinking of running a small honda generator in the rear compartment for long sand bar days.

How many batteries you have now? How many banks is that charger? Also, how many watts RMS using what amps?

Right now I just have small setup running probably 600rms, two batteries, I just hook that charger up to one battery and select ALL on the battery switch and it charges both. It's cool becuase when the boat key is on, you can see the guage jump up to 14.4v just like an alternator.

I have ran amps straight off of that charger to test sub boxes that i just built for cars.

Here is a couple of pics of the install.

Clean install!

Turns out the CTek's have a specific mode for Optima and Odysses batteries so I hope in the long run it will help iut last longer. I will probably replace my Interstate with an Odysses next year and leave the Optima in place.

When it comes time for me to replace my batteries (hope that won't be soon), I'll be going with a 6v battery bank for the stereo/accessories.
