hello i have a question if i am using dual battery off a 80hp outboard now will this charge both battery's?? here the tricky part one battery

Yes. I separated my batteries for one to crank the motor and one to run house accessories. When the motor starts, the cranking battery gets charged first, then when 13.2 volts or so are reached the relay turns on and charges the house battery. At this point both batteries are being charged at the same time. My boat has a 70amp alt on it and the system works great. Pain to install but well worth it. Hope this helps. ~ Robert

The Blue Sea is designed like a battery tender, it charges the main (engine starter) first. When the main is charged it will start charging the auxiliary battery. If you run your auxiliary battery a lot (accessories) then you will need to run the engine for quite a while to recharge or use a separate battery charger (110 volts). My suggestion is to install a small solar charger to help keep the auxiliary battery charged while using your boat and it will also charge up and keep charged your battery when not in use. This products does what it's supposed to do.

I just called Deltran (the company that makes these) and they said it is not intended to charge more than one battery because the charging circuit will only detect the charge condition of the first battery it is connected to, and so any other battery connected in parallel may not get fully charged.

I don't have experience using it on paired batteries. It sounds like it becomes a 24 volt system when paired up. I have a boat with paired battery banks it uses a much more powerful charger for them. However it will work well for your main engine battery by itself. You may need a 24 volt charger if it's paired to 24 volts.

I have two batteries myself...I keep the 2nd one always charged and ready to go when the other stops....then I put the charged one in the blower and immediately charge the 2nd one and it's always ready....as far as always leaving one in the charger without harming it...I really don't know but I prefer to charge the 2nd battery and put the battery and charger in a drawer until needed.

I'm not entirely sure, but the total charging output for two batteries is 10 amps. I would say a generator output of 1150 watts (amps times voltage = watts) would be needed. The on-line manual may show a more specific information. I don't have easy access to my manual right now since it's with my boat which is in storage right now. I will say that at full charge to both batteries, the unit does get very warm, thus the large heat sink fins built into the case. This is a well built, solid unit. I have had no problems with it. I hope this helps.

I have 2 sets on my pontoon and am adding 2 more I will definetly run a secon battery, but if you put a switch on them and use them for 2 or 3 hours, you could probably get by with one battery, hope this didn't muddy the issue to much . It's always nice to have a extra battery on board, in case your starter battery decides to belly up. Good luck and enjoy !

If you are running 2 battery's this will charge both at the same time with 5 amps. If you are running 1 you can hook up both leads and charge it at 10 amps so less charge time. Mainly depends on the recovery time you have between fishing trips.

The boat I use has a 12 volt battery, the outboard motor has an alternator that keeps it charged.

Yes, you can hook this up to two or more batteries. Just make sure to hook them up in parallel. + to+, - to-. This is a great starter kit, you can start with just this panel and one battery, then add more as you go. (If you are like me you will want more!) It would take about a day and a half to charge two car batteries when fully drained. My 122 amp hour marine battery will charge in a day. If you want a backup power setup more batteries per panel is better, but if you plan on a high daily usage you will want more panels per battery so it can recharge the batteries during the day.

I got mine hooked right up to the main battery in my boat.. I guess it's up to how long your gonna use it for.

Not exactly sure of the question but it will charge two trolling batteries at the same time. I would put the cranking batteriy on a two battery switch and charge it separately when and if it needs charging. You can separate your trolling batteries to avoid running down the cranking/starting battrty. Hope this helps.

Yes. This charger works 3 batteries. For my setup, I have for my boat a marine cranking battery. Then I have 2 full deep cycle batteries for a 24 volt trolling motor system. I used to charge them one at a time which was a major pain. Plus I never realized that with the primary cranking battery, running the battery off the alternator once running will not fully charge the battery. It will only get to about 70 percent full. However with this battery charger, it has an internal computer which will properly charge and maintain the battery. The other good thing about this charger is that if you only have 2 batteries, you can still use it. Just pair the other free connections to one of the batteries. I contacted ProMariner customer support directly and they confirmed this is possible and safe. Overall happy with the product!

The way I had to do it was look at the battery terminal, one is + one is - and the other is a T. I don't have it in front of me but I aligned the terminals on the battery to the pins on the charger. I think the battery was always flipped over with it's back showing. It did charge a couple times. We just came back from Hawaii. I thought maybe it was the cruise ship's wiring, but at home it did the same thing, would not charge no matter what i did or what battery I used.

I use it on a 12v battery on my sailboat and it works great. Every time I use my boat, the battery is fully charged. Doesn't need a regulator. Everything you need comes with it.

I would have to know all about your electrical system to answer that question, (battery amp hours, equipment draw, hours the equipment will be used, how often your main engine alternator would run, alternator output, etc. etc.) unless your boat has room for many large panels, you will not be able to recharge you battery fast enough to keep up. Your best bet is to add another large deep cycle battery. Solar panels recharge your battery/batteries when your boat is sitting and your equipment is not being used, (over a long period of time).

I've got a 12volt everlast marine battery. Seemed a little big for my pontoon but it works just fine. Don't have a fish finder yet but depending on the size of boat your using I'm sure connecting it to the battery wouldn't hurt. That's what I plan on doing.

there is no way to charge 2 NiMH batteries at once? adapter board such as the one for lipo? is there a dual charger designed to charge 2 NiMH batteries at once?
