Let Talk Batteries....

[ajholt7]

Just a year in my boat. I use the walmart batteries in everything I own though. Not bad batteries for the price.

Don't bother CHP, he's installing my new system...J/K. I went with Interstate batteries in my boat with one group 29 deep cycle (SRM-29) for the stereo, but I'm not looking for an all day play time. When we are on the water we rarely set for more than 30 minutes at a time. CHP is a great resource and I'm sure he can help.

Interesting discussion, I am looking to get an onboard charger for our new boat.

Does anyone know how the dual battery system is set up from the factory? I got this as an option on the 22Ve.

ok so my next question when you have a stand alone bank is there a way to run the stereo off the battery and alt when the engine is running?

If you're good with the electrical system you can rig up a cutoff to all but one of the batteries in te stereo bank. That will allow you to cut the additional battery(s) off while the motor is running which will do 3 things for you--
1. charge the one stereo bank battery while the motor runs so that you don't get stuck with NO tunes when your stereo bank dies.
2.allow you to charge all the stereo bank batteries with one charger
3. allow you to combine ALL the batteries to start the motor if your start battery dies

All you need in addition to your Blue-Sea add a battery setup is a battery disconect (or a Perko, but they cost more).

Im just going to keep the questions rolling so my system will draw probably around 75 Amps per hour so one battery at 75 Ah will last only one hour? So this battery would last a little over an hour on the lake(see link below)

Don't forget to get the marine version. Has the same specs and is right now on sale for $80 less and has free shipping. Same battery specs as the one you referenced. And it has the posts that are marine ready.

so was I right tho that the battery with 80Ah will run my setup for just over an hour?

yep CHP is the man!! hopefully he can get me rocking

I have a onboard charger in my 22ve similiar to this one:

I also have the Tige dual battery option and the onboard charger has worked great for the past 2 years. In the Winter I plug the carger in every couple of weeks and let the charger do its thing. During the summer I plug it in after every trip to the lake, let it charge for a while then take it back to storage lot.
As far as the way the dual batteries are set up, Mine has Interstate batteries one deep cycle and one starting battery with a on off switch. My understanding is all accesories run of the deep cycle and the starting battery is only for starting. My only question to the system is if for some reason the starting battery went dead would the boat be able to start off of the deep cycle?

haha evidently this topic has a lot of questions!!

You should have a Perko switch, right? If you put it on both, then both batteries will get power for starting.

I understand that from about 2007 onward, the Tiges have both a perko and isolator.

My Perko only has an on/off.

ok I don't understand the onboard charger... does it charge when I get home and plug it into the 110v outlet or does it actually charge when the engine is on? I am thinking I might have to do a stand alone bank which is fine but we boat sometimes 6-7 hours. Is there a way to have the speakers run off of the starting battery and alternator while the boat is running and then just have the stereo run off the bank when the engine is off? I would think that would be the most efficient.

An "On-Board Charger" is just a battery charger/tender that is installed on the boat that uses shore power to charge the batter(s) when the boat is back in it's slip or plugged up to the hose when home. This is easier then dragging out a charger as well as it's ignition protected.

The only thing to charge the battery(s) when out on the water running is the engine's alternator. But if the stereo's battery bank is too large, then trying to recharge run down batteries will lead too early alt failure. The real deciding factor will be how much play time you want with the engine off. This will determine how many Ah's you need, thus how many batteries. If you spend 6-7 hours running the system, then the last thing you want to do is fire up and let the alt see 2-3 dead deep-cycles. It will never be able to recharge them, and will have a heart attack trying so that's why I mentioned the possibility of a stand-alone

ok so my next question when you have a stand alone bank is there a way to run the stereo off the battery and alt when the engine is running?

The Blue Sea ACR will do just this, but it's not a stand-alone if the bank is getting charged by the alternator.

CHPTHrill what brand of battery do you recommend that won't break the bank?

There are only about half a dozon battery manufacturers out there, so, most of what you see are just re-badged at a lesser price. Some are made to lesser specs, but most are just the same. IMO, you cant beat the $$$ V's Ah of a good 'ol marine deep-cycle. The technology has serviced us well for years.

Does anyone know how the dual battery system is set up from the factory? I got this as an option on the 22Ve.

Your boat is set up with a diode type isolator. It allows the alternator to charge both batteries while the engine is running, but keeps the 2 batteries separated when the engine is off. This is a very simple yet effective system. The only real down side to the diode iso's is that they have a about a .7 volt drop across the diodes, so the battery doesnt receive the full output of the alt. For most peeps with a mid-level system, this is never a problem. Even with the .7 drop through the diode, the batteries will see a higher charge from the alt, then what is considered a full charge. The .7 drop just means it will take longer for the alt to recharge a run down stereo battery. And if you have read enough posts on here, i've commented a number of times that this is not what an alternator is designed to do.

I ran 3 battery setup (1 starting and a 2-battery stereo bank) on our Tige EIDB factory setup with the full Tige Tower O power, and only had low battery problems that summer when gas was $4 a gal. We would spend all day Sat and Sun at the sand bar, and by Sunday afternoon, the 2 deep-cycles would get low. Once back at the house, I hooked up the charger. So, as recommended, with any mid to hi draw system, it's best to at least have a charger to bring the batteries back up, and not rely on the alt, or have a complete stand alone battery bank.

All you need in addition to your Blue-Sea add a battery setup is a battery disconect (or a Perko, but they cost more).

All you need to do is add a simple on/off switch between one of the stereo bank batteries and the others, and have this battery be the one that the Blue Sea ACR is wired to. After a long day in the party cove, open the on/off switch to isolate the rest of the run down stereo batteries, then start the boat. The ACR will combine the 2 banks, as normal, but the alt will only "see" one small real low battery, instead of one huge run down battery. The ACR will allow the one stereo battery to get a charge, so the system will keep playing, but the alt is not working overtime on a job at will never complete.

Thanks Mike, great explanation of our setup!

I got the Tower O Power for our stereo setup, so it has all the regular cabin speakers, 10" WS sub, and 2 WS on the tower. I believe, and correct me if I am wrong, this is all powered by two WS subs.

Sorry to threadjack but this is some great info!... Are both of my batteries in the same location or is one in the rear locker, and one up by the spotter seat?

[petrey10]

mike you always help with your posts... What kind of Ah should I be looking for in a deep cycle? How big? I am thinking I am going to do one starting battery and then two standalone batteries for the system. What onboard charger do you recommend? I would love one that I could just plug in and leave plugged in so that way I don't have to worry about shutting it off after a certain time.
