I have 4 batteries in my boat. 3 in series for the 36V trolling motor and the cranking battery. Can I charge without disconnecting the 36V batteries?

You should disconnect them because it won't read it properly. If you have 1 bad battery it may read that one or read the good one... seperately would give a better charge.

I charge 4 I disconnect one but when you connect the Nicko it will tell you if it's right or wrong been having batterie problems for. 30 years since I bought this charger my truck starts up like a freaking airplane love it

I have three batteries on my boat each is connected through an 80 amp continuous solenoid. The set up works fine it keeps me from having to open the hatch to turn the batteries on and off each time. ALWAYS remember to turn off when not in use or leave the battery charger on otherwise they will run the batteries down. Hope this helps. Charles

you don't connect the motor to a battery charger you connect the motor to a battery..you could damage the charger as well as the motor

Yep, you should be able to hook them up to two 12 volt batteries permanently as the wires are set that way. I didn't have room to mount the charger in the boat so I bought some battery clamps for the end of the wires that hook to the batteries and charge them that way. When the batteries are fully charged, I pull the clamps, unplug the charger, and store the charger away. I like this better as I can see when the batteries are fully charged and not have the charger continuing to trickle charge the battery. Although, they say that is ok. So far, this charge works great!!

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry. I cannot answer that question.

I use this solar panel to charge two 12V batteries connected in series to produce 24V. my boat has two 12V batteries, but they are connected in parallel which is likely the case for your boat. Also, I believe that you should be looking for a 12V Solar panel, not 24V. Hope this helps.

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 installed the charger on my boat,(near the battery) then installed a Marinco Marine On-Board Charger inlet(also close to the battery) to plug the power in to charge the batteries. I had to cut the ends of the charger off and replace it with a male plug in the on-board charger inlet to plug in the cord to charge the batteries. works great.

You can charge it with a standard battery charger. Better to use a one amp trickle charge as with standard batteries. It holds a charge amazingly well and should work fine in your jetski.

Yes just make sure the battery connector is compatible with the boats connector.

No I do not believe so - I use mine on my boat with 4 - 12 volt batteries and it works great -- 6 volt batteries should require less amperage. So it should be more than sufficient. Bill G

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.

yes that is what I do in my boat for 2 rv batteries and it works great. make sure and get the power regulator so you don't over charge your batteries.

I use it to charge the cranking battery in my boat. It does a good job of bringing it up quickly. The guy I get my batteries from is adamant about unplugging the charger once the battery 's up; he's uncomfortable allowing it to float charge. Says he's seen a lot of batteries that get cooked dry when you leave the charger on all the time, even if they are designed to maintain the battery. Not sure about that, but I do it anyway.

I installed it as a battery disconnect in a 20 foot bow-rider motorboat. It disconnects the marine starting battery for a 5.7L V-8 motor which was experiencing a parasitic discharge.

What the previous responses said! Marine battery, motor mount, trolling motor and battery box. I would also recommend picking up a trickle charger if you don't have one yet to charge your battery when not in use.

I have two of the mentioned chargers. I can't answer your question since I keep my chargers plugged in to 110V when boat is not being used. I have owned for a couple of years and am very satisfied with product? These are solid state chargers and should not drain batteries unless there is a problem with chargers or possibly wiring connections.
