Onboard battery charger

[River918]

Thinking of putting one in. I have four batteries in the boat, 1 set to position one (used to start the boat) on the Perko switch and 3 (for the stereo) on position two. What chargers are you guys using and which ones do you recommend?

[DILLIGAF]

Here is the one I use.

Used to have a generator but took it out. I didn't like the heat and other possible problems that could occur. I am much happier with the charger. When I leave it in the slip at night I just plug it in and by the next day my 4 batteries are fully charged. When the boat is in the garage I plug it in there also. Works great. One thing I had to do was change the plug from the 20 amp plug to the regular plug.

I had Frank at car toyz in Havi install stinger batteries [3]and an on board charger and never had problems starting or playing the sterio.

Tremor, Which one did you use?

Did you check out the one I posted the link to?

Not to hijack your thread, but does anyone not run the stereo off the alternator? I was thinking this weekend while starting the stereo install about leaving the 3 D31M's seperate from the boat except the ground. I have a battery charger that I will plug in and use only for the stereo batteries after each outing - about one day a week, two if I am lucky. That way I can use the existing two batteries the way they came on the boat - Position 1 for one battery and a second battery on position 2 connected to the alt through the perko. I have about 1500w system going in. I don't think we will be playing at max very often - two small kids.

Get the little blue charger/battery maintainer from energy1.com. Its made for boats and engine compartments is waterproof and very small. Works great. Check their Northstar batteries out too....they are wonderful.

Yes I did, I'm just checking all my options. I've seen pictures of boats with the one I linked to and was curious of what people thought of them.. Thanks for the info

We have 2 Odyseey 1700's that are 100% stand alone and don't tie into the alternator. We have each one hooked up to an Iota DLS55 charger and just plug them in after the day on the water.
Our last boat with only 2 batteries left us stranded a couple of times and I vowed to not let that happen on this boat:)

My bad didnt see this question until now. Ill look at it over Memorial Day.

Thanks, that was what I was hoping to hear. My friends were screwing with me last night betting on how long before the stereo cut out on the lake once everything gets hooked up. I figured I would be good for 1-2 days at normal operation.

1-2 days;)
It really depends on the system you built. How much power the amps are drawing off the batteries.
I have 4 amps totaling about 1600-1800 watts and I can kill both batteries in less than a day if we are cranking the volume.:devil: :D

[Cole Sanger]

The system is 3 Optima D31M's and the amps are a total combined peek power at 1320w. We have two small kids, so it I think it will be fine. The original system I designed had the three Optimas on position 1 for the perko and the original two batteries on position 2. Worst case, I go back to that.

Im using the IOTA DLS-55 also on 2 odyssey 2100's with 2 kicker KX850.4 and a Phoenix Gold 600.1 and it will play for a 3day weekend without a problem at moderate volumels. Honestly I dont know how long it will play since it has never cut out on me even after 4 days on the water. I have 2 small kids also so very high volumes dont happen very often. But the DLS-55 charges them easily overnight. I like it because it can be left plugged in for months if you want. It monitors battery level and shuts off completly when not needed then turns on when voltages drop to a certain point.

I've been using that model to maintain my Optima blue tops for three seasons now.

Guest makes a great charger for Marine use. My last boat had a Guest and I have a Guest installed on my Rhino as well.

I bought a couple of these and they seem to work just fine. They come with a bracket, mounted them to the transom. I bought them on sale for $7.00, and they keep the batteries fully charged. I even tested the batteries and there were perfect.

I went the harbor freight rout as well. For the money couldnt pass it up. So far no problems

[mbrown2]

A Xantrex charger is no better than any other good quality three stage AGM charger. I use an IOTA DLS75 to charge two submarines batteries, which have the power output equivalent of 10 Odyssey 1700s. My system is completely isolated from the boat's electrical system, so I can only recharge by plugging in. I can get about 14-16 hours of playtime at moderate to not so moderate listening levels.
Ditto...I blew up two Xantrex 40's...they suck...had to switch to Cascade/Iota 90 in my last boat....Xantrex could not take a charge from a honda generator...eu2000....Cascade/Iota never had an issue.
SWBob...how much do those batts weigh?
