Will it charge 2, 12v batteries connected in series for 24v. Boat uses 12v for lights, pumps, 24v for motor so 12v is used more.

Since charger works when engine not running,it will charge both 12v Batts regardless on how they are connected
268261
I don't know I don't have a third battery you can not charge just one battery you have to have both batteries hooked up to each battery connector

This system is designed to sense the power of two separate 12V circuits with one battery each. Each is separately monitored. Connecting two in series (or in parallel) defeats the monitoring.

Ok this might help. I hooked 2, 12 v batteries in series (24V) and with a stand alone 12v (I have a dual charger). Turned the charger on and the lights flashed but went out. No charging. Hooked up two 12Vs individually and both batteries charged perfectly. Hope that helps..

That is an excellent question. I'm sorry but I just don't know, but I can try it and see what happens.. Tom

I do not know. I would call or email their customer service and ask for a technician for that answer.

We have been using these to charge one battery at a time. We use it on a island in Belize. Some have two terminal but cannot remember if the one a above does. I don't be going out yo the island until next week if you need me yo check them please let me know.

if you have 12v batteries in series your adding to the voltage therefore your batteries together are 24v not 12 anymore. if they are in parallel then you will still have 12v just double your amp hours. this charger says its for 12v only i wouldn't recommend it.

You can connect as many 12v batteries as you like. You just need to make sure to connect them in parallel, if you connect them in series you will have some serious problems.

yes that is correct. If you connect two 12v batteries in series end result will be one battery bank of 24v. When charging batteries - use of a charge controller is highly recommended.

Yes. My boat has an automatic on-board charger. Any 12volt automatic charger will work.

Assuming you place 2 volt batteries in series, a 24 volt source will simultaneously charge up to 12 batteries. however battery amperage varies with the capacity of the battery, so you could charge multiple rows of 2 volt batteries. However I suggest that you see someone that understands power generation before proceeding further.

Yes, I currently have mine hooked up to 2 12 volt batteries. It brings 4 cables, 2 per bank, the positive and negative for one battery, and the positive and negative for the second battery.Great Charger!

Yes. Mine charges both batteries at same time. It's a 2 bank charger - 10 AMPS per bank. I have a seperate 1 bank charger for my cranking battery. It has seperate wires for each bank to hook up to your two batteries for your 24volt system.

It should trickel charge both. It will not charge if one of the batteries is dead. I use it on my 2 boats and a jet ski, but they all have one battery.

you can only charge 2 12volt batterys. cant charge them wired in series that gives 24 volts. cant charge 3 batteries.
1239097
Yes. You connect the battery with the charge controller. This is only for 12Volt battery. If you have 24volts, you will need to replace the charge controller with a MPPT one.

You have to hook up battery's in a series. It will charge 6 / 12 volts at a time.

Honestly I don't know. I don't do much boating, but if the connectors are similar to that of a car battery then there's nothing stopping it from working. One thing I do know is that if it's a sealed lead acid battery do NOT charge it when the voltage gets near 11vt. It'll ruin the battery. As far as the equipment is concerned, I must admit there was something wrong with the packing and they sent me the wrong stuff. I bought a different charge controller called the 'cyclopse' and it worked fine.

This is really for charging 12v batteries. Not aboe to directly charge laptops, etc, becuse the output in 12V from the controller. We use this on our RV to charge 4 marine batteries with the 30AMP controller, and run inverters to run appliances. It would be overkill to use this with inverters just for basic recharging, but it CAN be done.

I would not recommend it unless you are using as a system to charge for several SUNNY days after each use. This is a 75W charger. You could look at potentially buying two chargers, just keep in mind these are solar, so you are dependent on the sun, but it did work great for my boat battery. If you are driving a lot, you might want to look into buying an alternator or if your boat is not designed for one, you might want to consider a portable generator. It really depends on how you plan to use the power source.

Not sure, The unit is designed for 12v deep cell low amp batteries used on boats to power radios, fish finder and lights but not to start high amp engines batteries to start car and boat engines.

This charger will charge any six (6) or twelve (12) volt battery. It is not the type of charger you would leave inside a boat for charging. If you remove the batteries from the boat or charge them in an open area where there is no possibility of a fire or explosion you will be pleased with the results. I use them for my boat but I stay right with the batteries and charger while the charging takes place. In general, this is not a Marine charger that you would install in a boat. I have several of these chargers and have been extremely pleased with the performance and when I required any information or help, the Factory was very helpful. I hope this answers your question.
